I have to admit that I fall under the category of people that have a pile of holsters that I hardly use, but I still don’t think they are worthless.   I think it’s always good to keep spare  holsters around incase you break one, wear it out or have to wait awhile to get one custom made.   I’ve had situations where a favorite gun holster broke and it took a few months to get a replacement.   When it comes to needing gun holsters for hard training, I think it’s always a good idea to know ahead of time on how many magazines you intend to be carrying.  Blackhawk Serpa holsters are outstanding combat holsters due to their superior durability and stability, but some nylon holsters will still work very well.

There is a point where I think people have to be realistic about how many handgun magazines they are willing and needing to carry and how much bulk they want.   At a certain point  you really need to put more thought into carrying  a Carbine if you want that much firepower.   There are gun holsters with a drop leg setup that will allow you to carry more magazines that are off the belt line, this can be a tricky configuration to use and I would put serious thought into whether or not you want that bulk, but it will free up your gun belt for cell phones, flashlights, radio ect.
