I see that there are a bunch of replies already, but I was once in your exact position where I didn't want to wait five plus months for a 1911 holster and decided to make my own. As for tools, I used chiacgo screws for assembly versus stitch the first time around which means as long as you have a sharp cutting tool and a drill or punch to make holes you can start making a holster. I read up on the internet some challenges people faced in this sort of project and distilled the info down and finally just bought tool grade leather and went at it. Wet forming leather was an interesting to learn and a pretty neat process and in the end I wore my holster for a year without issue until I had an opportunity to buy a nice one. Really just go for it, it's an uncomplicated venture where failure means you smell of leather.
