One of our retired Sgts has been making holsters for our people for several 3-4 decades. Below is one he did for my Glock. It's a mahogany basketweave. It's been carried a lot on duty. The 2nd one pictured he did for my S&W 63 in brown. It's been carried a lot while hunting and overall probably has had rougher treatment due to being carried exposed and thru brush. They both still look and perform like new.
Cost is about $40. Turn around time is about 1 week. He uses very heavy leather. He's a perfectionist. If it's not right he won't ship it.
If you're interested send me a PM and I'll forward you his email.
I don't know if he has a large trigger guard S&W for a mould. I have a 6904 with a large trigger guard that he could use if needed.
