Hi,
Indeed! Break/fix things and make mistakes during your training and practice. This article had a lot of good tips. Sure, most of us have BTDT for a lot of these conditions, but it was a good review, and a great reminder to practice. You know I love to practice.
I have a couple of pistols that would fail to slidelock after the last round. Yes, it was due to my thumb riding the slide release. I have changed my grip and thumb position a little but got plenty of practice "fixing" in the meantime. If I pulled the trigger and got a "click", just drop the mag, slam in a new one, rack the side, and carry on.
In class the other day I performed an "administrative" reload in the holster. When we started the next drill, the mag dropped after the first shot. Doh! I grabbed my spare mag, slammed it home, released the slide, and continued the drill. I had failed to properly seat the mag during my admin reload. It was noisy and I didn't hear the "click". Next time I'll make sure. Why perform an admin reload in the holster? It's good practice if you have to reload with only one hand.
Fail to prepare, prepare to fail. Let's be careful out there.
Thank you for your indugence,
BassCliff
