I have a G40. I love love love it! I have about 300 rounds of Underwood 200 grain FMJ through it. Worked great! The weapon is accurate and shoots great. The only thing that I have against it...this is purely my opinion...is the grip texture is too aggressive for my liking. Gloves help that problem for me. My husband and I couldn't decide if we wanted it then we saw the serial number. The first for places of the serial number is BALZ....how many out there can honestly say their GLOCK 10mm has "balz"?
