Sorry for just responding, I was in the shop putting some finish on some projects. I don't have a website yet, but I do have a Photobucket page with some of my work on it. Here's a link to the section with 1911 holsters on it.
The Beretta 92 has a grip about the same length as a 1911, so that's a good starting point. Do you like the way your current holster carries it, as far as rake, and ride height? BTW, congrats on your first 1911!!
As far as IWB goes, a couple months ago I took this photo to show the differences in a 15 degree (the dark brown) and a 25 degree (tan):
Glad you like it Sheepdog!
