Howdy all, from the CO Rockies. I enjoy most brands and builds but recently decided I wanted a durable, reliable, mud and blood gun. Decided on a G20sf for my first Glock. Put a few rounds down range and was in love. Got a Lone Wolf long slide that I'm gonna have milled for my DeltaPoint before I refinish it. Now I gotta learn about co-witness iron sights, whether I want the rear sight in front or behind, and just about everything. Several buddies tell me this is the place to come and get some answers. Don't worry, I'll try the search function before I do much pestering.
