I just bought my step-mom a Glock Gen5 17 last week. Improved grip. Only complaint is the slide release bar that like all Glocks is too flush and nearly impossible to grip.
It is not the flush finish. It is TOO smooth for an “older” hand to grip.I’m an 80 year old and hands can’t grip the side of my LC9. Older fingers have smoothed out skin. The problem is NO friction and the fingers just slide off.
I simply but a strip of EMERY board, sticky backed onto the slide, either side. Works like a wonder.
Even as a youngster, I had trouble with the slide on a .45.
Oh, the same piece of “emery board” still as good as the day I put it on, 3 years ago. Try it.
With glocks it is better to train yourself not to use the slide release and just release it by gripping the slide and pulling back until it releases. Fine vs. Gross motor coordination.
