Thanks for all the replies. Had no idea people aren't shooting that much SA at all anymore. With my GP100 I'm spending about 75% of the time in SA and 25% of the time DA. Does that mean I'm practicing wrong?
Yes . . . and No!
No, you CAN'T go wrong practicing, as long as your technique is good.
That being said, it is always interesting to see shooters sign up for their first "Pin Match." Bowling Pin matches are shot at a distance of 10 yards (a good self defense distance) at good ol' heaving wooden bowling pins that are sitting about low-chest high on a heavy table. The object is to clear the table as fast as possible, for that's how ya win.
New shooters start trying to shoot single action and quickly realize other folks are clearing a five or six pin table in mere seconds shooting double action.
Next match, if they come back, they are starting to shoot double action. Yes, they are still as slow as molasses, and they are missing a lot because their double action technique hasn't been perfected where the trigger pull doesn't pull the sights off target, etc. . . . BUT, like I said, you can't go wrong practicing!
In time I've seen some fine, accurate single action plinkers, who would almost surely die quickly in a gun fight . . . turn into some pretty darn decent handgunners too!
As someone said, in an emergency you'll be shooting fast double action only anyway, just trying to keep the other guy ducking and running . . . so you need to learn to precisely hit what you need to hit every time . . . shooting fast and double action.
SUGGESTIONS . . .
Go to some handgun matches where revolvers are shot. You may just be comfortable hanging around and getting to know folks at first, and that's fine. You'll find, virtually without exception that the nicest and most helpful folks in the world are handgun competitors!!!
Soon you discover they are pulling for you in matches, no matter how you do, and encouraging you in every way . . . and you become a master with your firearms. You'll also learn to shoot more EFFICIENTLY and correctly watching what the best shooters do!
It is a lot of fun too!
