Storm lake conversion barrel - Stormlake Pistol Barrel for 34033 GL-22-9MMC-449 For Glock 22 9mm Conv For 40S&W/357Sig 4.5" SS

Have 3, two of them are g22 to g17, one is g23 to g19, zero issues with the 3 I own, all function fine, haven't noticed an accuracy increase but I mainly shoot Glocks 2-3 times a week roughly 500-1000 rounds a week. Only probly is the threading on one of them, why the F would you thread a 9mm barrel 9/16x28? Retards. These were for cheap .40 cal police tradeins, and with the correct ejector, extractor and spring loaded bearing they run good. Still have a larger breech face but still get about 3-4 foot ejectuon with the correct 9mm parts in the 40 cal pistol. If you gotta change to 9mm this is a good barrel
