We have 3 kinds of belts in use with my department:
1. Mixson real leather belts, high-gloss.
2. Nylon belt with the release like you described.
3. Uncle-Mike's el cheapola crapola nylon with glossy crap over it that looks ever so cheesy.
(Can you tell how I feel about #3?)
#1 is solid, rugged and dependable, but stiff (its
leather, what do you expect?)
#2 is rugged, dependable and comfortable, but it looks less professional. Thus far I can think of no instances of those belt clasps giving way under pressure from a fight or weight from, ah, excessive donut-induced girth.
#3 is completely a bad idea. It looks bad. It tears easily. It allows your holster to twist easily on the belt, and if you have a Level III, that can make drawing the gun problematic. It is a waste of money.
I have figured out part numbers/item codes if you're that interested in what i know works and what I know doesn't.
