Update: Retired the 17 with Trijicon HD's, now resides with my brother-in-law, after nearly 5000 flawless rounds. Now carrying the USA made 17 with I-Dot's, like'm a lot. The Gen4 19 just installed Heinie Slant-Pro 3 Dots today. Next is a JM Custom Kydex OWB holster for it. Wanna kill these ads? We can help!
