So lets talk holsters. I'm in the market so to speak.

First of all this is for my warbelt, only used for gun games, C4, my private property, or in the case of zombie out break/open hostility.

Retention? Drop?

Guns in holster with be Glock 17 and 21. I will probably buy for the 21 and the 17 will not be used with it for anything real.
