I have carried a Glock 23 and 36 in one of these holsters, as daily wear, for years. They fit well and have shown only minmal wear (a few scratches here and there). Very comfortable if you don't wear your trousers too tight. Most of the time I don't know I'm wearing it. If you wear your belt/trousers a little loose you may have some droop (same as with a belt slide).
I tried to order one for a 1911 a couple of months ago and they were out of stock. If you do order one, please let me know if they're back in stock.
