Last night at class a few students and I started talking about which is better the old standard button vs HK levers for mag releases and also which digit to use thumb or trigger finger. I mentioned that I'd only just learned that Todd had been using his trigger finger with his Beretta and M&P back in the day, and was surprised by that. Of course speed is the issue that seemed to be the forefront of the discussion and my opinion was that neither technique or device is the limiting factor when changing mags. It is the speed with which you can get to your mag pouch, draw the fresh mag and get it in the gun that determines your reload time. The important thing is to be proficient with your method of release. I find the button activated by my thumb works best for me, but I have big hands and don't have an issue reaching the button on most guns. In my limited time using HKs or Walthers I found my thumb preferable but didn't have a hard time getting used to using my trigger finger either.
Thoughts?
