My favorite carry gun is a P2000SK. The size is somewhere between a G26 and G19 and I love the feel and relative safety of the TLG LEM trigger for AIWB use. I have some Boltaron AIWB holsters with extra length (JMCK) that work great but I've found that I prefer leather holsters. I feel they are more comfortable since they do not have molded in channels for slide release levers and stuff that can cause hot spots for me.
Anyway I've been looking for a while at leather AIWB holsters and several of the more well known ones are either out of my price range or out of my attention span for leadtime. I really liked the idea and look of Del Fatti's ISP-A2. It's sort of a Summer Special with straight drop and grip tuck wing. However, it falls into the high price/long leadtime and he does not offer holsters for my gun. So I decided to shop around for an obtainable option.
I ended up finding Overland Gunleather recommended by some on HKPro. I didn't see an AIWB offering in their lineup so I contacted the owner about what I was looking for. By providence, he was actually in the process of creating an AIWB holster design and was testing one out that he had made for his own G17. It looked exactly like what I was looking for. So we discussed it and I placed the order. 11 weeks later, I received this and am very impressed with the craftsmanship and design.
It is natural leather with the rough out and black mouth, loops and full sweat guard. It has a wing for grip tuck and some extra length. It also features 10 degrees of reverse cant. It's very comfy except the extra length is angled a little too much towards my inner thigh and was rubbing. I contacted Overland and he said to send it back and he'd get it modified to my liking. I'll post again when I get it back.
The owner is a real nice guy and responded to my emails within hours. He also shipped my holster with a nice thank you letter for the business.
