*Stainless Steel Finish Units are IN STOCK and ready to ship*
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.
