Most self-defense pistol classes spend some time making the point that you should train as you carry with regards to type of firearm and ammunition. I know that many competition shooters train with, as an example 200 gr bullets in 45 vs 230 gr. How does a competition shooter practice for self-defense with the heavier ammunition/recoil and then drop to the lighter stuff for competition without compromising the muscle memory for self-defense, or inversely affect his competition with practicing for defense? I am not asking how competition makes you a better shooter or saying one is better than the other, I am asking for how the comp shooters manage the mental/physical difference between the two. I will probably never shoot competition as I simply don't have the time or finances to dedicate to that as much fun as it sounds like it is, but I do compete with myself in the defensive arena as $$ allows in the form of ammunition, training when I can and drills when I cannot. Will it matter much to me? Well it could as the cost of material to reload can be cheaper in the lighter weight stuff. That was the basis of the question.
