I hear about this, but have never actually seen it. Never had a problem with my Glocks or other pistols.
Thanks for the video ! It helps explain the phenonomen to my wife, who fires the G22 and the M&P 3.8 in 9.
The glocks always seem to give her issues. She gets frustrated by it, but tends to blame the gun. I can see both sides to this.
I have a G22 (Full size slide) with a grip-chopped frame (Down to G27 dimensions). It’s broken in quite abit, and it operates very well - But yeah, you gotta hang on to that sucker for effective results.
Apparently you aren’t a limp wrist.
