Hi FA,
Congrats on your new weapon! Let me tell you,your going to love that pistol if you can get happy with the trigger! My 45 was VERY hard and I didn't hesitate to do the mods on it. I showed a buddy of mine the pistol and he drooled on it for a half hour,guess I bought the last one in the county and he wants a 45 model BAD! To be honest the only thing I have shot in mine so far is my reloads using a MiHec clone H&G# 68 200 Gr. boolit. I have not tried any HP ammo yet. From what I've read there should be no problems though!
I just put a 4.25 PRO model in 9mm on layaway and noticed that the stock trigger on that is really pretty nice and will only need a fluff and buff! Go figure!
