It's been a while since I've posted anything, and my results have been steadily improving, thanks to all that I've learned here. Here are four IWB holsters I made recently. Two are for a Government length 1911. One of them has lizard skin trim. The light brown one turned out splotchy for some reason, due to the boning/molding process. I used a vacuum bag to do the initial forming, pressing with my fingers through the bag, and then with bone folder for details. I haven't had that problem before or since.
The other two holsters are an adjustable IWB design that I made for a Colt Defender and a Smith & Wesson M&P40. The snap loops are screwed into T-nuts, which can be moved to change the cant and ride height.
I used 7/8oz leather from RJF leather, Fiebings Oil dye, saddle stitched, finished with Resolene and then a coat of Sno-Seal. I mostly used Hidepounder's edge burnishing method, but I'm getting inconsistent results, with the dye rubbing off during the final burnishing. On the last holster I dyed the edges after sanding and burnishing, then used glycerin soap, saddle soap, and paraffin wax.
On the last holster, I also forgot the coat of neatsfoot oil after molding and before using the resolene, so it ended up a bit splotchy. I was in a rush...lesson learned!
