anyone have a Safariland 567 holster? I got one today and my gun doesn't seem to fit it very well.

I'm using a CZ P-01.

I thought the holster was supposed to be able to fit like 100 different guns but it only lists certain guns on the packaging. I was told a holster for a Glock 19 works for a P-01 and this holster says Glock 19 and 23.

I can adjust the screws a bit and it will fit in pretty snugly, but its too snug to pull out of the holster.if i unscrew the screws any more, they will be sticking out pretty far. will holstering and re-holstering make it fit better or should I return it and get something else?
