Hello Sawlog!
I have used Kramers and Sparks leather for concealed carry for 30+ years, carrying everything from J frame Smiths to N frames, as well as various models of the 1911, and the "plastic" autos.
Hands down the Kramer belt scabbard (pancake) in horsehide, IMO is the finest outside belt carry today. I carry using a Sparks 1 1/2" belt. The holster is thin, because of horsehide, snuggly and perfectly fitted to the handgun and with minimal care still looks nearly new after many years of daily wear. I currently have nine of these, and buy one for any newly acquired handgun I may carry.
For IWB carry, I prefer the Sparks Heritage or Summer Special. You will receive top quality with either brand. Finally, no disrespect to other posters but I personally have not had a problem with sliding the Kramer scabbard onto my belt. Good luck!
