Throw a snap cap in and practice away. I found that after a few minutes it becomes controllable and the force needed to release the slide becomes instinctive.
Nothing becomes 'instinctive' after a few minutes.
It never did that for me. I must have weenie arms? :-)
I think I shot the G26 for the first time the same day.
During USPSA, I don't recall slamming the mag that hard.
If you're reloading at slide-lock during a match, you should plan the stage better.
Didn't fully load a mag, I though I did, it was embarrassing. And that happened 3 times, one on each trip.
