I’ve used a C-TAC for years and I like it a lot, but it’s not easy (for me) to put on/take off. It’s a put it on and wear it all day holster. That’s great when I can carry all day.
I also use an Infidel. It’s not as comfortable as the C-TAC but it has one huge advantage. It’s easy to remove and replace. When I have to go somewhere I can’t carry I remove the holster with the gun still in it and skip the unholster/reholster steps I’d have to do with the C-TAC.
It’s a lot harder to make an ND happen if the gun never leaves the holster.
I like that.
