Sorry if I gave the impression that I thought the tight holsters were substandard. That isn't what I intended. However, I have never had a holster that stretched out only from the firearm itself being in the holster. All that have been very tight I've had to put layers of plastic bags around the gun and leave it in for 2-4 days to get the leather to stretch out so that the gun could be drawn without pulling your belt up to your neck before the holster let go. I'm sure a lot of this has to do with the fact that until January this year with the passage of Kansas' CCW law, I did not have a firearm in a holster on a continuous basis. It would only be in the holster during a competition or range work, but then it came out for storage. My only thought on how these new holsters fit is that they don't have to be stretched out to begin with yet hold the firearm firmly enough to not fall out. Plus, since they fit so well to begin with and I don't have to "break them in", I'll do much less damage to the finish on my firearms than I would having to scrape them in and out of a holster until it breaks in.
It is done very intentionally and is not a happenstance of the maker not knowing how to fabricate a properly fitting leather rig
