Try galco's classic lite shoulder holster, they make one for a 3913, I have a Galco ankle lite that my CS9 and Glock 26 both fit in, BTW this thread would be useless without pics
You're right it's still suede, try uncle mike's pro pak horizontal or sidekick vertical shoulder holsters, I have no experience with them but they are nylon, and a few are available on Amazon, sorry that's all I have to offer up.
