The strongest handgun in the world is the .44 magnum revolver.

http://popularmechanics.com/outdoors/firearms/2003/9/top_gun/ MODEL 500 S&W MAGNUM REVOLVER In the 1971 movie "Dirty Harry," actor Clint Eastwood introduced the world to the double-action Smith & Wesson Model 29 .44-cal. Magnum revolver--"the most powerful handgun in the world." It was a crown S&W wore proudly, albeit briefly. The rising popularity of handgun hunting for big game (spurred largely by the .44 Magnum itself) prompted the introduction of newer and significantly more powerful revolver cartridges. Many powerful enough that they had to be chambered in single-action handguns because existing double-action designs could not contain the recoil forces and pressures they produced. Since S&W does not make single-action revolvers, and no double-action frame at its disposal could handle the new loads, S&W was effectively dethroned. At the 2003 Shooting, Hunting and Outdoor Trade (SHOT) Show, the manufacturer regained its crown. And, most significantly, it did it by introducing a new massive double-action revolver that is chambered for an equally new .50-cal. cartridge. The S&W X-frame Model 500 is a brawny handgun designed to master the most rigorous hunting fields in the world. It is not a revolver one would, or likely could, tuck into a waistband. In fact, to call it massive is an understatement. With its 8-3/8-in. barrel, the overall length of the Model 500 is 15 in. and the empty weight is 4.5 pounds. The cylinder alone is almost 2 in. in diameter and approaches 2.25 in. in length. Thumb the cylinder open and five charge holes await. Each is 1/2 in. in diameter, and the .50-cal. cartridges they hold are almost 2 in. long. Load five of them and the total weight of the handgun climbs to 5 pounds. You don't just casually pick up a Model 500. You have to lift it. Fire even one of those big cartridges and you'll appreciate why the weight and mass are there. When the .44 Magnum laid claim to being the most powerful handgun in the world, its standard load produced about 900 ft.-lb. of muzzle energy. Several new loads have since eclipsed that, but the handgun most commonly used by big game hunters is the .454 Casull, which will generate about 1900 ft.-lb. The 500 S&W Magnum will produce almost 2600 ft.-lb. with its heaviest load, and more powerful loads may well be on the way. If Dirty Harry felt that the .44 Magnum would make his day, the new 500 S&W Magnum would certainly make his decade. It is the largest double-action revolver available, and there is no production revolver in the world--single or double action--capable of matching, or even approaching, the level of power it produces. Harnessing that power in a double-action revolver, however, required some departures from traditional designs. Rethinking Double-Action Design No frame in the S&W line was capable of containing the 500 Magnum, so the new X-frame was designed specifically for the 500's .50-cal. cartridge. It is massive. But, just making a bigger double-action revolver was not the solution. A major concern was the barrel-to-frame connection. This is traditionally done by simply screwing the barrel into the front of the frame, but this design places all firing stress at that one point. To increase strength throughout the 500's barrel assembly, S&W opted for a composite barrel/shroud system. A stainless steel barrel tube is torqued into the frame to form a solid rear attachment point. A separate, heavy stainless steel shroud is then slipped over the barrel and braced against the forward portion of the frame. The muzzle end of the barrel bears against the forward end of the shroud, and a separate compensator/muzzle brake is then rotated into place under torque at the muzzle end of the shroud. This arrangement compresses the shroud and places the barrel tube under tension for its entire length. In effect, the barrel and shroud act as linear springs to distribute the stress of firing across the entire barrel/shroud component instead of focusing it all at the single junction of the barrel and frame. Maintaining precise cylinder alignment was another concern. Traditional designs utilize a front- and rear-cylinder lockup, with the forward end of the ejector rod bearing against a ball-detent fixture on the barrel to provide the front lockup. Given the power of the 500 Magnum, the potential for flex in the ejector rod had to be addressed. The solution was to dispense with that design and install a massive ball-detent lock on the frame itself, directly below the barrel forcing cone. This mates with the yoke to provide a solid front lockup directly at the front of the cylinder. Combined with the traditional rear lockup, this is the strongest cylinder alignment design possible. While the 500 S&W Magnum answers the question of "where's the beef?" the company wisely decided to incorporate the same grip dimensions found on its much smaller K-frame handguns. Experienced handgunners regard this as one of the best handgun grips ever made. Thus, the 500 Magnum is a big revolver that's strong where it needs to be, but is comfortable to handle. That was borne out during firing tests. On The Firing Line Despite the power of the cartridge, the 500 S&W Magnum is surprisingly controllable. Due largely to the sheer mass of the revolver (combined with the muzzle-heavy balance and an excellent muzzle brake), the violent wrist-wrenching muzzle whip associated with single-action revolvers firing such powerful loads as the .454 Casull and the .475 Linebaugh has been tamed considerably. In those guns, muzzle rise on recoil can reach 90° and present a hazard to the shooter. With even the heaviest 500 Magnum load tested, muzzle rise was confined to the 50° range and there was never any concern about the shooter wearing an imprint of the front sight in his forehead. That does not mean it's a pussycat. Make no mistake about it, this is not a handgun for the timid or the inexperienced. In comparison tests, the lightest 500 load--the 275-grain jacketed hollowpoint at 1665-ft.-per-second (fps) velocity--produced a modest, but noticeable, increase in recoil levels over a S&W Model 629 .44 Magnum. Anyone who is uncomfortable with the .44 Magnum will be decidedly uncomfortable with the 500 Magnum. The 440 cast-lead load at 1625 fps raised the recoil bar significantly. Muzzle rise still remained under 50° and placed little or no stress on the wrists, but the rearward thrust absorbed by the shooting hand began to become uncomfortable after 10 to 15 rounds. A shooting glove would have mitigated some of that. Still, considering that the projectile weight and velocity of this load is virtually identical to a 1-ounce 12-ga. rifled lead shotgun slug--and that the 500 Magnum operates at over four times the pressure level of the slug--the recoil was less than expected. We'd say that Dirty Harry would certainly approve. **There are 4 more articles from Popular Mechanics related to this handgun. They can be linked to by using the link I provided at the beginning of this answer.**

It's ironic that when Dirty Harry advertised the .44 Magnum as "The most powerful handgun in the world" (in 1971), it was in reality, not. Designed nearly 13 years earlier was the 454 Casull cartridge designed by Dick Casull and Jack Fullmer. Though the bullet weight is roughly the same as the .44 Magnum, the velocity it traveled was nearly double.

I measure pressure and velocity of ammo for a living and I can tell you that a 454 Cassull has has a higher velocity and higher pressure coming out of the barrell of a gun than a .50 caliber, a .480 Ruger or a .44 Magnum.

Magnum Research, Inc. makes a .50AE pistol called the Desert Eagle. This is a semi-automatic pistol. Magnum Research also makes a BFR revolver that is chambered for the 500S&W. http://www.magnumresearch.com

The most powerful handgun in the world is infact the 44.magnum desert eagle not the 44.magnum revolver.from luke in Tockwith

LAR's .45 win mag,hence the Grizzly Win Mag

Well, I have a .45-70 Contender and a .30'06 SSP. both are technically handguns though I don't know the ballistic data for them, I know they seem a lot more powerfull that either of my .44 mags.

The 740 Howda,74cal african tiger stopper.you can't buy one thoe.

A loaded one!

Thats a tough call, the 44 Magnum has a kick back and fire like a donkey kicking you in the chest and the .45 Ruger is just as crazy..

.50cal, however my favourite most powerful and accurate hand gun is the .454 Cassul by Freedom Arms. This is a deadly accurate and powerful revolver and a fine display of American Craftmanship, I live in Australia and own one of these.

44 magnum of course, was it six shots or was it five, the question you have to ask yourself is "do you feel lucky........PUNK"

The most powerful handgun is now the Smith & Wesson .500 Magnum, delivering 2600 ft·lb of energy compared to the paltry 900 ft·lbf oozing from the teeny-tiny .44 "Magnum".

The one that is aimed at you.

The dessert eagle is pretty powerfull.

.50 caliber Desert Eagle.

Without any question, the Maadi-Griffin .50BMG Thunder http://airbornecombatengineer.typepad.com/airborne_combat_engineer/2005/01/the_thunder_50_.html It does push the boundary of 'handgun', but I have seen it fired and it handles well.

yea i like the 50 calliber desert eagle

The Smith and Wesson .500 magnum is the current most powerful. It makes other .50 cals seem like rimfires. S&W makes a revolver in this chamber as does Taurus. http://en.wikipedia.org/wiki/.500_S%26W_Magnum Now there are handloaders out there that can make a .44 magnum more powerful than the .500 mag but that's pretty hard on your weapon.

http://www.answerbag.com/images/answers/temp/6516/tmb_bullets.jpg http://www.answerbag.com/images/answers/temp/6516/tmb_bullets.jpg This GunWeek photo shows a .499 LWR (far right) next to a .500 S&W For equivalent bullet weights, the .499 LWR can achieve higher velocities (as high as 2200 vs. 1900fps) and higher muzzle energy (as high as 3000 ft-lbs. vs. 2600 ft-lbs.) than the new .500 S&W pistol round. (The longer 18" barrel, vs. 12" for the S&W .500 pistol, helps, by allowing full powder burning in the barrel.)

My money is on the Maadi-Griffin .50 BMG handgun. Is you think that a .50AE is even a pale impersonation of a full BMG round, you are mistaken. The Maadi-Griffin packs more powder in one round than the S&W Model 500 does in the entire fully-loaded cylinder. Even if most of that energy is wasted due to the shorter-than-optimal barrel, it still can put a hurt on that a little pea-shooter S&W can't match.

if you said 44. mangnum your wrong theres a gun called 50.cal Desert Eagle it has higher velocity and a bigger cartridge and way more stoping power.

The .500 magnum. "Make my day, punk."- It'll blast your head clean off.

Apparently the .500 but before I would have gone for the Isreal Military Industires Desert Eagle .50 Action Express. I hear they have made them in full auto? Hopefully with an extended mag because the capacity is 7 so the soldier would be reloading alot on full auto! The .50 DE looks so COOL it's my favorite handgun I have 2 airmodels, someday a real one.

a lot of people are saying that its the Dessert Eagle and stuff...im positive there are handguns that actually fire rifle rounds, but i dont know the brand

Megatron

500 magnum by far

the .60 cal

the most powerful production handgun in the world ( that is NOT a singleshot ) is the magnum research BFI revolver chambered for the 450 Marlin cartridge.Yes,the 450 is more powerful than the 500S&W magnum.Jimmy the gunnut

Of course the most powerful is not really the best. I would rather be carrying a glock 20 10mm loaded with 15 200 grain bullets from double tap or corbon than a 500 S&W.The most powerful handgun is the one that you hit the target with.Misses or slower repeat shots mean nothing when you face a dangerous animal or a human killer.The 450 marlin is tops in power,the ammo is cheaper than 500 mag,the 450 is a belted magnum with like 3500 pounds of kinetic energy.POW!

i heard that some idiot broke his' wrists firing a custom pistol in 600 nitro express.There is supposed to be a video of this on the internet but i haven't tried to look it up.600 nitro makes elephants sit down involuntarily.I'm sure that that handgun is now sitting in a safe somewhere daring some moron to fire it.The 454 and 44 mag are the most popular big handguns.The 44 mag can also fire 44 special and the 454 can fire 45 colt,the reverse is not true.Remington makes a 180gr 44 mag at 1000+ FP energy,other companies have more robust loads at 1200 and over.My favorite big bore load is the 454 240 gr Hornady,it is twice as powerful as the 44 mag 180 grain.A 44 mag shooting 45 colts is a PLINKER,no kick.A 44 mag shooting 44 special,same thing.450 marlin is top dawg for repeating handguns.

Now, here is the worlds largest revolver. Also manufactured by Pfeifer Waffen.

ok all i can do is laugh. People keep calling it a .50cal eagle sorry its not a .50cal eagle it is a .50ae..Its like comparing a .45acp to a .45 long colt it shots the same bullet but it is not the same round..The most powerful handgun produced is the .500ae smith and wesson..Before that round was made the title to the most powerful revolver was to the freedom arms .454...I own this handgun not a cheap taurus or a ruger but the real freedom arms. It is a monster and if I recall correctly it is still the only revolver to take the big 5 out of aficia..so for all the people who think it is the ".50cal" eagle sorry your wrong....

I would say it is the Thunder .BMG.

The most powerful handgun is the one that is loaded and pointing at your head! Caliber doesn't matter. Never point a gun at someone unless you are willing to shoot.
