The IWB holster that I just made for my Colt 1911A1 feels a little loose to me. I have a training gun that was meant to teach field striping and such that I have had since I was a kid (non-firing of course) that I used for the boning and shaping. The "dummy" fits quite snugly--I can turn the holster upside down and shake it fairly vigorously and the pistol won't fall out, but the real thing is a little loose. I can upend the holster with the real thing in it and it won't fall out, but a little shake will dislodge it.
Once I put the thing on though, I can jump up and down, do push-ups and jump off of things and the pistol won't move, but I just have a feeling it should fit in a little more snugly. IWB seems to be inherently more secure in that respect, but I was wondering, are there certain areas to concentrate on when boning the holster to get a tighter fit? I keep reading about holsters that are so tight that they are difficult to draw and re-holster the weapon at the start, and require a break-in period.
How can I get my holsters to fit tighter, or do you think maybe my "dummy" gun may be a little oversize? I may have to break out my calipers and see...
