A question came up in another thread relating to emergency reload techniques used to send the slide into battery after inserting a new magazine. I did not want to derail that discussion too much and I wanted to share my experiences with employing the "Auto-forward" technique during an emergency reload and why I DO NOT use it on any of my pistols. My duty pistol is an M&P9 (fullsize) that I have owned for about a year and a half. Prior to that I had an earlier production M&P9 fullsize that I had owned for about 2 years prior.
For the first 2 1/2 years I carried the M&P9 as my duty weapon I almost exclusively relied on the "Auto-forward" technique when conducting emergency reloads during training. Nearly ALL of my training was done using FMJ/ball ammunition. During a training session where I was using some different types of hollowpoint ammo which included my duty ammo (Winchester Ranger 124gr +p Bonded), I experienced a malfunction nearly 5 to 7 times out of 10 which resulted in the top round in the newly inserted magazine getting hung-up at the bottom of the feed-ramp on my M&P9. I continued to experiment with different hollowpoint loads which ended-up with similar results.
I sold my earlier production M&P9 recently and I just picked up a brand-new M&P9 fullsize from my FFL today. I decided to test out the "Auto-forward" function of the new pistol to see what my results would be. Here ya go....
*Of course my Flip video camera software is not cooperating, and for some reason it will not upload the video I took onto YouTube. I will try again tomorrow.
Basically, The brand-new M&P9 that I just picked up today would not chamber a round when inserting the magazine in a manner that causes the slide to "Auto-forwad". It would chamber a round fine using the slide-stop and the over the top method of releasing the slide, but the "Auto-forward" causes all kinds of issues with this new pistol.
