I've used a 3S with a 1911, Beretta 92 and 5906. I liked them except that it did not allow for Condition 1 carry with the 1911.
The belt loop sits rather low on the holster, causing the gun to ride a bit higher than some other IWB holsters. They work well with longer barreled handguns, but I'm not so sure with shorter barrels.
I do like the ease in putting on and taking off as well as having an adjustable cant.
Doesn't answer really as far as your gun, but that's my experience with them.
