So in my guise as a firearms instructor I’ve acquired a closet full of holsters in the last 5 years, some make the cut some don’t, some are wonderful and as we all know some suck and either don’t hold the weapon secure or are painful to get on or off or are just painful- as OP states crossbreed and molt sparks are all good stuff, I’ve also had good luck with Alien gear holsters but lately I’ve been very pleased with Stealth Gear holsters, and just ordered a 3rd, for Glocks, 1911s and Sp101 revolver. Very well made attaching it to belt or pants is easy and secure, whatever “stealth “ technology they use on the part the contacts your skin, does not move, slip or chafe nor does it make me sweat- my name at deer camp is sweat hog- so if I don’t sweat you won’t . Holds sidearm very securely and as an added bonus for auto pistols there is an option for a kydex magazine holder that goes on the front of the paddle in the most convenient unobtrusive ingenious way and it’s very secure and easy to access with the off hand so if your armed you have extra ammo on board no matter what for no increases in size or another thing to attach to your belt.
the above review is my findings I’ve no connection to any mentioned company nor make any money from my experience based opinions.
