Just got a new MTAC for my glock 19, and I like it pretty well, but I'm having one issue I wonder if anyone else has experienced. I went with the 1.5 inch c-clips from the maker, and I'm having a hard time getting them to stay on the belt, especially when standing after sitting. I'm using a quality 1.5 inch gun belt (Aker B-21), but when I measure the MTAC clip, I notice that it's actually about 1/8-1/4 inch more than 1.5. It seems like a small difference, but it's just enough to cause my belt to wriggle-free. I guess I always have the option of going to a standard clip, but one of the major selling points of the holster for me was tuckability, and a big part of that is the more discrete c-clip. Anyone else having this problem?
