I just have some advice Glock owner to Glock owner. I got two from the Glock Store, and both failed almost right away. Also I would keep mine personally OEM, if your 27 carry weapon. What gr. rounds are you shooting? If you are shooting 165 gr. maybe try 180gr. Rounds. They seem to be less snappy IMHO.
