Malfunction City - Glock 19/23 Build
This video details a Glock 19/23 build that experienced significant malfunctions when chambered in 40 S&W, despite running flawlessly in 9mm. The builder suspects the aftermarket stainless steel guide rod or the compatibility of the Glock 23 slide with a 9mm conversion barrel is the cause of the failure to feed issues. The build highlights the importance of ensuring component compatibility for reliable firearm operation.
