My local shop is a Blue Label dealer. They just got an Sxx prefix G17L in. All my Glocks (19C, 35 and 21 Gen 4) have been RMR'ed, and have suppressor sights for the BUIS. I'm thinking I need a pistol with just iron sights, so I can still be proficient with irons. This G17L seems really nice.....and 9mm is cheap. Should I buy it?
