The .50 GI™ Glock 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 Glock 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. Glock 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 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.

    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.

    Guncrafter Industries .50GI Drop-In Conversion for Glock Pistols

    Posted by David Koenig on Feb 17th 2021

    Absolutely fantastic workmanship and well worth the wait. A perfect fit on my Glock G21 frame and the finish work is fantastic. In addition, I've had the pleasure of dealing with Dru on a couple of occasions to clear up a few things and she was absolutely AMAZING! It's refreshing to to hear someone on the other end of the phone that actually cares about their customers and Dru personifies that attitude. Clearly, Guncrafter Industries feels the same and I'm honored to help support a company like this one. Keep up the good and innovative work, folks.

    Very well made. Only issue I’ve had was the bullet at times not able to move up into the barrel.

    50 GI Drop in Conversion - Glock

    Posted by Stewart Dunaway on Aug 31st 2020

    Easy as pie. Off with my Glock40 upper and on with the 50 and insert a 50GI magazine and you are all done. I had not fit issues. I had no firing issues. I shot all but the led ammo - and had no issues. I was very pleased with the finish (Stainless) the parts were all well made. I even disassembled the upper to see the firing pin, safety plunger etc. and was 100% satisfied. NOW I wish I had 1000 rounds of ammo!!!! Love to shoot it - very very close to 45acp in terms of performance and "feel" with recoil etc.

    This is incredibly fun to shoot. Fit perfectly onto my Glock 20SF frame right out of the box. I'm very satisfied with this purchase.
