Oh ! WoW ! I use mine on Thumb Safety, and Retain springs only ! So far so good. The pointed use for aliment. Made plastic for non scratch to your frame.
Good to hear from different options and experience.
I used to carry GLOCK 22 Gen4 .40 S&W for duty firearm. I've seen other officer shot suspect. Two rounds your going down without any problems. We use Hornady Critical Duty ammunition.
I like .40 S&W, .44 Special, .44 Magnum, and .45 ACP.
In Milan Illinois I pay $175.00 Yearly, Indoor and outdoor range. Plus they want you to be a member of NRA. It's expensive but worth it. I go shooting weekly and do competition shooting at the facility.
