Not bad Lonerider.
I have a question as a layman of the medium..
If those holsters had open muzzle form, would they not fit every Glock frame on the market?
9mm and 40 cal are same frame size, 45 is larger, or so I'm told. I have a G-30 mold that's a short barrel and will make any of those to fit any length bbl.
As a crossbreed owner/user, I can answer your question Tim. The answer is yes they would work for all, except maybe the single stack, and you are right about frame sizes Lonerider. My Crossbreed was bought for my G19 but carries my G26 most of the time and works quite well for it. It also carries my G20, but it is admittedly a little tighter fit for it. They all stick out different lengths past the kydex but stay on the leather. You can see the different impressions they make. If I were buying to primarily carry a larger frame Glock .45 ACP or 10 mm, I would want to buy one for that frame size. Mine is mainly for my 9 mm with rare usage by the 10 mm; so, I'm fine with the way it fits.
I'm not quite ready for the leather game, but have been considering tinkering with kydex. Maybe sometime in the future when I have more time. Holster making seems like a good/useful hobby.
