The .50 GI™ Conversion Unit will fit any Generation 1-4 Glock® 20/21/40/41 frame. This unit comes ready to install with no fitting required.

These conversions are hand-fitted right here at Guncrafter Industries, and come with the same great warranty and support that all of our 1911's come with. The 50 GI™ conversion has been designed around the caliber. These aren't modified parts, they are hand-built from the ground up with the intention of giving the end user the ability to have 9+1 of .50 caliber rounds in your large frame Glock® pistol. This makes a great CCW pistol, a hunting pistol, or just a range toy to impress your friends. 

Don't be intimidated at the thought of 50 caliber recoil out of a polymer frame pistol! Because the 50 GI™ is not in the magnum family, and because the round operations with such low pressure, you will be pleasantly surprised at how controllable a pistol platform firing 50 caliber rounds can be. 

Simply field strip your pistol, replace the upper end with your .50 GI Conversion Unit, load your supplied 9 round magazine, and you are ready to take advantage of the most controllable 50 caliber round available. These barrels do NOT have polygonal rifling, nor are they affected by firing lead projectiles. 

Will fit standard holsters for your Glock® model.

Extra magazines available in our store.

Our Threaded 50 G.I. Barrels use 5/8 - 24 TPI, RH Threads with a 5.3" OAL

The conversion for Glock® pistols does not need to be shipped to an FFL. 

 

 Make sure to select your finish options, and what generation you need. If choosing a Cerakote Finish, select the Stainless Steel option. Cerakote is NOT applied over Melonite. Please call for custom options. 

*adding Cerakote or RMR will create a 4-6  week extended lead time. Due to COVID-19

*Our Glock® conversion units with RMR cuts do not come with sight conversion kits. They are direct mounts for RMR / SRO sights. For other sights, it will require a sight conversion kit from elsewhere.

 *Frame not included.

    Precision Crafted Performance

    Posted by Pete Greene on Apr 22nd 2024

    Wow. Fit, form, appearance is flawless. Nice tight tolerances, no rattles, not a scratch, rub notta zero.
    Haven't had the privilege of pulling the trigger yet however looking forward to that 1st shot moment. Was on the fence for some time making this purchase. No regrets, should have done sooner. To the folks at Guncrafter (hats off) to all from engineering thru shipping. 100% flawless all the way thru the process. Highly recommended Manufacturer! Great Experience and thanks to all again!

    Amazing!!!

    Posted by Jackie Redway on Jun 15th 2023

    I love the conversion. Simple swap of the slide for oem Glock lowers. I had an issue at first with clearance over an aftermarket locking block, but after reading the very detailed instructions accompanying this sweet conversion kit I realized there was excess material on my locking block. I swapped out the block and now the slide moves freely like buttered cheeks on a thanksgiving turkey. Highly recommend this for anyone who wants something that stands out or more stopping power with a recoil of a 10mm. The machine work on the barrel and slide are immaculate with high attention to detail. Beautiful beveled edges on a pristine stainless finish 10/10

    50 Gi upper

    Posted by Anthony Gary PhD on Mar 15th 2023

    The 50GI caliber has to be one the most unique firearm invention on the market today. The 50GI is easy to install and works just as the inventor Mr.Zimmerman intended to. The 50GI has many advantages over the typical .45 ACP caliber in that it's first a .50 caliber and has more mass and more momentum so it delivers more damage to it's intended target without being uncomfortable to shoot. The 185 grain copper projectiles is just a miraculous bullet, it's all copper and precision engineered to expand to 1 inch in diameter while not breaking apart, incredible! The 50GI is so versatile in many ways , you can load it with the Hornady Xtp Magnum bullet that can be fired at 950 ft. Per second while staying at standard pressure 23000 , incredible. I love the 50I. It's made in America , thats always good. Try one today!!!

    Drop in Conversion Kit

    Posted by Patrick Lutz on Oct 19th 2021

    Excellent components to be sure. I did have a little binding at the top edge above the chamber which I filed evenly and now the barrel does not hang up. I should be getting out to the range fairly soon and should prove to be a good experience. Thank you

    Excellent Quality, exceptional idea

    Posted by Nicholas Kleban on Oct 13th 2021

    I absolutely adore shooting my Glock with this conversion. I do not approve of half measures, and knowing the lead heading down range has the same weight as my .500 s&w keeps me smiling. Alex and his company have produced a truly excellent product. I can’t wait to purchase a custom 1911 in .50 gi in the future.
