I think you'll find quite a few on this forum carry a Glock either some or all the time. I re-aquired my G-26. For about 6 years I used it or my S&W 442. I also have a G-36, which is about the size of your 23, but a thinner grip & lighter. I also carried a 21 for over 10 years, but not concealled.
None of them have failed me. They're not pretty, but they're reliable (All mine have been at least), accurate, & reasonabley priced.
