Great info, thanks! I was thinking about focusing primarily on revolver carry holsters...I really don't see a whole lot of them out there. I also understand the importance of creating/building a holster that has a reason and is not just a copy of what's already out there. Specifically, the IWB design for the snubbie that I have started similar to the IWB for the Kimber above it. The problem i ran into with the holster for the Kimber is that, although it functions well and would probably work well for some people (skinny people that is) it just doesn't keep the butt of the gun close when moving around. So, my logical solution was to add more leather to the bottom of the holster. Understanding that the pivot point is where the snaps hold onto the belt as the bottom of the holster is pushed out the top of the holster and butt of the gun are pushed in towards the body. Problem solved.
And, the snubbie owb design for the snubbie with the heavy cant was created by request of my wife who didn't like a straight up and down cant and wanted the gun to cant heavily forward like a SOB design. So i struggled with the design for a while because i could see how to attatch the left side of the holster but couldn't figure out an asthetically pleasing way to attach the right side until i let go of the idea that both front and back halves have to match. Plus, I think I saw your IWB design that uses a similar concept and I was able go from there. I had been searching for a way to change the inside of the holsters so it wasn't just a rough side in. I toyed with the idea of using different materials but, logically, the only good material is leather. I was looking for a contrasting color and like a side of tooling kilp that I found that had a nice cream color to it and thought it would go well with the light tan. So, I worked on the design to make sure my stitch holes line up when sewing the lining on and then attaching the front to the back. Also, since I'm hand stitching, I needed to make sure I took into consideration the back stitching that you do at the end to make sure it didn't end at a stitch hole that would be used again.
So, I just wanted to respond to your comment by saying that I'm not just copying designs. I've genuinely reinvented the wheel, so to speak, and am going through the though process on what's working and what isn't. As you mentioned, there really isn't anything new, mainly variations on the same concepts.
I agree with your comment on the belt loop holes. They could probably be a bit wider. I'm just trying to figure out a good way to make some clean holes. The loop punch works nice to make a clean cut so i may stick with the "punch" process but i may try other types of instruments to get a uniform look. Thanks again for the comments.
