I'm sure most people have talked about this but I was just thinking about it. I think that this works really well b/c as far as I can tell. As long as you limit the usage you should be fine and even if you don't it shouldn't really cost much to do basic maintenance a little sooner. Most people say you should practice with what you plan to use for self defense, mostly for familiarity of the recoil. Well to be honest I can not tell any recoil difference between standard 9mm and +p+ but then again I am still used to the 45. Are any of my statements here wrong or just any other thoughts?
