I have a G20, I put in a Zev trigger and had them do the stippling and remove the finger grooves. I also put in a KKM bbl. with a 20lb recoil spring and had the slide milled out for a Trijicon RMR. When I carry it, it's usually in a Blackhawk Serpa holster or Diamond D's Alaskan Guide rig. Loads I use, Underwoods 200 gr XTP, and also a handload 12.4 gr. AA#9 under a 200gr. JHP. While it doesn't look as good as my single actions...it does have a good round count and it's light. I'd include a picture but I'm new and haven't figured it out yet. I haven't shot anything but paper and steel up till now. The Springfield TRP looks awesome! They also have that now ready to go with optics. And with my aging eyes, I'm definitely leaning more and more towards optics.
