I know this issue has come up in several threads over the past few months, but I figured another one in a different direction would not be a bad idea.
I am an armored car guard in California. In July, the exemption for people in our industry to possess and acquire high capacity magazines effectively goes away unless the firearm or magazines are somehow company-issued and kept at the branch when not in use. I carried a Glock 17 beforehand but I have never been impressed with how the 10-round magazines worked with anything but ball ammo. If you shoot anything like JHP or leadless "sinterfire" ammo through it, the magazines bind on the last round or a little bit of the follower goes "crack!" and falls off, or something.
I bought a glock 26 in preparation for waving my high capacity magazines goodbye and have been openly carrying it at work for the past few months. It's a little weird, but it's 10 rounds and it works. That said, a part of the reason for carrying a firearm is as a psychological deterrent, and for that I prefer a mean-looking full size handgun.
I'm asking for PF's anecdotal experience. Have you ever owned a full-size pistol, especially in 9mm, where the 10-round magazine works as well as the full capacity, even with ammo designed for shooting things other than paper?
