You can't practice the actual scenario of being attacked. You can, but you can't. No practice is going to compare to the scenario when your adrenaline is running. Or at least most people don't put themselves in a realistic scenario when practicing. (Adrenaline and Panic levels.) I know I don't have the right belt to carry .45, but I'm never going to be carrying a .45, I was more or less saying my pants would fall off just to say there is no need in carrying a .45 with the extra weight that comes along with it IMO. 9mm +P ammunition has more than enough power to take out an attacker. With the trigger pull aspect, do you think that's going to be a big deal in a CCW situation? All you need to be able to do is hit paper from 7ft away, which I think most people that shoot regularly could pick up a gun and hit paper from 25ft away no problem. If you're pulling your gun on someone 25ft away you better think twice about pulling that trigger.
