The .50 GI round should not be compared to the Desert Eagle’s .50 Action Express or the .500 S&W. It is slightly more powerful than the .45 ACP.

    hey…thats kinda sexy. i wonder how recoil is.

  • gun guy

    The .50 GI operates at pressures comparable to the .45 ACP, around 15,000 psi (100 MPa). Interestingly, felt recoil is also similar to the .45 ACP. Also, the .50 GI is moderately accurate bullet. The 300 grain (19 g) JFP (jacketed flatpoint) produces a 25-yard group of 2.24 inches, and the 300-grain JHP (jacketed hollowpoint) and 275-grain JHP produce a 25-yard group of only 1.14 inches. source… http://en.wikipedia.org/wiki/.50_GI

    .50 CAl. Glock Great Idea. Go 4 It. The Bigger the Better ! U.S.A.

  • Glockenspiel

    Why didn’t the US Armed Forces pick this over the M9?

  • macf

    Because, genius, the trials that led to the selection of the Beretta 92F(S) as the M9 pistol were many years prior to this conversion being created.

  • me

    What was glock thinking? $600 for a .45 conversion kit? I wonder how much it cost to develop and get the manufacturing equipment for a glorified 45.

  • kelley

    I’ts put out by guncrafter industries, not glock. Have another look at the ad.

  • Wingman

    They should develop a conversion kit for the Desert Eagle. At least then, the pistol would be of viable personal protection use (obviously a holstered pistol). Then turn it back into a magnum when you hunt, silhoutte shoot or just feel like pounding the hell out of yourself when you fire it.

    Large cross section, a little more velocity than the .45, moderate muzzle blast and recoil-I kind of like it.

  • the raj

    I am hoping Glock will strike up a deal with Guncrafter when the next ban comes around. If I can only have ten, why not make it a .50?

  • Chris

    Does anyone know if i can use this conversion on my Glock 30?

  • Dan

    I fired one today, very impressed. recoil like a .45. Hollow point opens up to like one inch. Now that is a home defense pistol.

  • robert

    they most likely could not develop a conversion kit for the DE. The 50gi, unless self loaded at hotter than normal loads, probably could not cycle the DE. In a DE, the barrel doesn’t move, unlike most handguns where the barrel cycles with the slide. The DE relies on pressure going around and under the barrel from the fired round to push the slide back, which is a whole lot less efficient than most other handguns.

    why would somebody take a 10mm and make it less powerful,less capacity,less accurate,more exspensive,heavier,and cycle slower? just the facts

    I wonder if a 700# Bear charging you would notice any difference between the .45 and the .50 GI?

    I know they would with a REAL .50 Cal pistol like S&W!

    AR15 uppers in .50GI are now available, $750:

      Giesler, thanks for the info. I will post it on the blog.

    @ Viperguy and Sprocket:

    I was a dyed in the wool .45ACP guy until the .50GI came out. You guys are missing the point of the round. It’s not the 10mm, it’s all the TKO but one of the blast or recoil. It’s not the .500 S&W or “bear medicine,” it’s a practical CCW round. Take a look at the ballistics and you’ll see it is a round with a TKO that dwarfs the .45ACP, yet it has the same recoil impulse and is available in a standard 5″ 1911 or Glock 21 conversion. A very clever bit of engineering.

    Hi Everyone..Here is some info and pics that i did earlier.. I have posted this on a few other forums..

    Had some extra time on my hands yesterday so i took a few hrs at the range to do some of my own Balistic comparison testing using 3 sets of wet soapy phone books submerged for 1hr measuring a total of 17inches per stack..And below i have posted some pics of the depth results and expansions…My velocities might not be accurate since my guns are not full length in size so you might wanna average a few hundred fps less than what is listed below..All tests were shot from a distance of 17ft…I will list from best to worst..From my tests the best expansion was the 50GI SCHP which measured 1.05″ Shot from Glock21SF .50GI conversion 4.6″ Barrel…2nd place 454 Casull Barnes X HP,expanded .65″ ,Shot from Ruger Alaskan 2″ Snub…3rd place 10mm Federal HydraShock expanded .63″ Shot from Glock29 3.7″ barrel…. 4th place The Gold Dot and Magtech .45 both expanded at .50″ Shot from Glock21sf 4.6″ Barrel… 5th place The Winchester SXT expanded at .48″ Shot from Glock21SF 4.6″ Barrel…and the Aguila had no Expansion when shot from Glock21SF 4.6″ Barrel..The Aguila bullet is a fragmenting bullet that is suppose to fragment into 3 pieces when impacting soft tissue…In this case nothing happened so i gave it last place…As for penetration I have it listed below with the pics..The penetration results i tried to take exact measurements since it was hard to do this with a measuring tape using phone books..The Best penetration so far that i have seen from my guns is the .454casull penetrating at a whopping 15″……Hope you guys enjoy the pics and feel free to comment.

    Would love to see this on the Glock 30 models!

  • Diesel

    I’ll stick with my 10mm thank you!!!

  • Dan In KS

    Just another way to get your money, if you cant kill it with a 45, you should stay in your condo.
