I compete with a gen 3 Glock 17 and sro, and I carry a gen 3 Glock 17 and sro. Identical set ups, my carry gun is lower round count and not used for practice sessions, but serves as a match back up gun. I have a 19/Rmr combo at home, but that’s really more for my wife than me. The only thing I may change in the future is carrying with an aimpoint acro or Steiner MPS. I snagged a brownells acro slide and had my original Glock slide with internals sitting around to throw into it. I love the SRO but it collects a bunch of dust and dirt in the window
