Stormlake 34042 - Stormlake Pistol Barrel for 34042 GL-23-9MMC-402 For Glock 23 9mm Conv For 40S&W/357Sig 4" SS

This is the best bang for the buck conversion barrel. The fit and finish are on point and it is easy as 1 2 3 to install. The accuracy with this barrel has greatly improved from the worn down .40 cal used barrel. I highly recommend this product especially for a small amount more than the lone wolf. 2 Thumbs up!
