I didn't vote primarily my personal training and experience is that I will do what the situation calls for and it will also depend on what weapon I am using. My Glocks I often hit the slide release after loading a mag. No stress, under stress, gloves no gloves(note here most of my shooting gloves have the thumb and trigger finger removed for better feel and more control of the pistol) and have yet to miss the slide stop with my Glock. Now on a 1911, due to the fact I have medium sized hands and need to roll the pistol to hit the slide release I just rack the slide and let it fly. On my H&K P7 I use the squeeze cocker to drop the slide. Anyway, what I am getting at is I adapt to the pistol and situation when I am shooting, I will use whatever is quickest and most difficult to mess up, be that the slide release, racking the slide, or when shooting left hand, without the aid of my right hand even racking the slide on my belt. I don't buy into one way is king, I buy into economy of motion, that is what you need to train for, start off slow with each move of the reload broken into one move and train until all those moves become one move, then once you get there adjust and adapt as you need depending on the platform and the situation.
I don't think that is a sign of excessive wear. My personal, and I do stress personal experience, has been that a Glock that has been broken in and that does not have the extended slide release will drop the slide when a loaded mag is inserted with significant force. With the extended slide release this is rare. Just my experience, train for it not to happen and just react appropriately when it does.
ETA: Half the time on my Glock when a insert the fresh mag I hit it in pretty hard to make sure its seated, and when i do a LOT of the time the slide itself will close when I do that.....Is that a bad thing?
Or did I just prove your point about it causing excessive wear on the slide release?
