to the original question... I built a G17.3 with a Trijicon RMR2, and the sight completed its one year continuous on anniversary in October, I changed the 2032 battery... the slide was milled by BattleWerx for the RMR, and they did an excellent job... I added the thin bottom plate by DPP Titanium, and just cold blued the machined surface and a spritz of Birchwood Casey barricade for protection... the slide was in good shape... as my vision deteriorates with age, I find that it is becoming more difficult to find the front tritium lit sight, and the red dot makes a much better low light platform for me
the second G17.3 had a slide update to a Swenson machined for a Venom, and carries one of the Venoms... it is in a Recover Tactical brace in a car bag, Streamlight ProTac1 in a Viking Tactics mount
I've started competing in Steel Challenge, and have switched to Holosun 510 dot scopes (with photo voltaic cells) for both the 10/22 and MkIV 22/45 lite....the Venoms are having to find other jobs...the large format lens makes it easier for me to track the dot... regards
