I’m not one for upgrading my carry weapon, but was thinking of making my new G19C more enjoyable to shoot. I started off by undercutting the trigger guard (that helped a lot). My next upgrade will probably be a set of Trijicon HD XR sights, and a Glock factory raised slide release. The only other things I could see doing would be to add a non ported barrel, flat trigger shoe, and a $.25 trigger job. Do any of my mods have a bad track record with reliability? Where would you draw the line on a carry weapon?
