Filing and fitting required if not take to a experienced gunsmith - TRYBE Defense Glock 22/31 .40 S&W to 9mm Cartridge Threaded Conversion Pistol Barrel

Ok so upon reviews I see people with issues running this barrel even I had “Fitting” issues but after inspection some may need to hold down the slide stop release “little piece to remove the whole slide “ you will be able to get this on now the problem I came to was slide being out of battery meaning slide did not close all the way so I had to file a tiny bit on the breach face by chamber and bam it fitted shot some 9mm and no issues
