This sounds interesting. I'll have a Gen3 G21 and if it works on that I just might get it.

It is a .50 GI round which isn't that impressive. It would be better to stick with the .45 for self defense maybe the .50 at the range just to say you have it? lol

.50 GI cartridge

From Wikipedia...

The .50GI operates at pressures comparable to the .45 ACP, around 15,000 psi. Felt recoil is not unlike that of the .45 ACP. The .50GI has developed a reputation for accuracy, though this may be due to the high precision of the semi-custom and very expensive Guncrafter pistols themselves. In one test, the 300 grain (19 g) JFP (jacketed flatpoint) gave a 25-yard group of 2.24 inches, and the 300-grain JHP (jacketed hollowpoint) and 275-grain JHP gave a 25-yard group of 2.14 inches.

The penetration in gelatin (but not necessarily the kinetic energy) of the .50GI is significantly different than the .45ACP, as it was purpose built to have a recoil impulse and kinetic energy substantially less than the magnum .50 caliber rounds such as the .50 AE (semiautomatic) or .500 S&W Magnum (revolver). Factory loaded ammunition has a kinetic energy of around 500 ft·lbs.

The cartridge is rarely used in law enforcement or for personal defense due to limited availability of ammunition and guns chambered for the cartridge. Currently, the only commercial handguns available in this caliber are Guncrafter Industries' own Colt 1911 handgun variants and its Glock 20 / Glock 21 conversion upper, and Magnum Research chambers their BFR revolver in this caliber on a custom basis.

I'd get it to say I got it and show off. "Look what I can do!!!" That would be about it.

I say if you want a .50 cal get a desert eagle Mark XIX or the S&W 500. Cause the .50 GI round wont come close to the power those produce. You wont be disappointed, trust me lol.

I would leave the 21 they way it is.

The .50 cal ammo will be more then the .45 acp ammo. I know for the .50ae its about $1.60 to $1.70 a round. You forget about that when you pull the trigger an see a ring of fire and hear the thunder

. I cant get enough of my desert eagle lol.

+1, aside from the 'first kid on the block to have one', it's not got anything going for it IMO

I'd take a pass on the .50GI. It seems to have inherited the costs of the .50 caliber family, but only offers the ballistics of a high-end .45ACP.

When I move up to .50 caliber in a handgun, I'll be looking at the .500 S&W. 300gr bullet, 2100fps; 700gr bullet, 1200fps; reports of reasonable accuracy out past 500 yards.
