So I bought the Glock 20 SF after doing some proper research into ballistics and decided that I wanted a 10mm round. Came with the standard gear, so I bought 2 more 15 round mags, and all the 10mm ammo at three separate stores. Attached is the Surefire A62440, 150 lumens but with great throw for such a small light... It's like a mini spot light. I put some tru glo fiber optic sights on it, but I think I'll replace them for tritium, as they show up black at night even with the surefire light on. Shoots great, recoil isn't bad at all. The spring had that 'springy, metallic sound' to it but after some Frog Lube, she runs like hot butter. I put some frog lube in the rails as well since the light was a PITA to take on and off, now I can take the light on and off with ease. Highly recommended, the trigger reset is a lot better than most semi automatic pistols I've shot, short of Sigs new SRT trigger. I still love my Glock 30 trigger the most. That said, I love this gun.
