Most any decent gun will do 100, it's mainly mental, been there done that. My thing is magnification you see your heart beat, you learn to time your shots to it. I like a moderately light trigger...11oz. Some do really light but I prefer a touch of safety, no pun intended. I like Arken FFP Scopes, I LOVE their simple reticles with a .3 moa center dot instead of a massive cross hair or even a thin cross hair, put dot on target and let fly. I lube everything that moves, my trigger groups get either Tri-flow or Mobile 1, the light stuff, nothing special and I've got a bucket full of special gun oils. Personally I do Mavericks, I'm familiar with them, I can tune them, I know most of the issues with the 'barrels' , you'll read about how FX POI shift from day to day, as long as everything is properly installed, short of using it as a pry bar they are fine, every gun shifts a little, it has to, I carry mine by the scopes the barrels the frames, whatever I grab. I prefer Donny FL Moderators, I've got another box of Mods, I always go back to my Donny's, I put a small 1/2" or what ever size thread it is, 0-ring, it helps to seal the Mod to the barrel, and possibly help with accuracy but also keeps the lead dust going away from you.
