i agree completely, but like lots of others, i have guns that i shoot for competition type fun and have done trigger work and a host of other things to, but would never consider them as a carry weapon, and you are right, they would not be safe to use in that role, my 24/7 gets roughed up allot just hanging out w/ me all day, and yes i am very confident it will go bang if i ever need it to, and that it won't until such a time.
it is still a little bit of a learning curve everytime you go out and practice again, getting used to it again. after shooting other guns and going back to it, my first shot is almost always high and right, which is bad because that is the one that may matter someday, at least the 2nd is always real close to where it should be.
