Wow, please stop it man. You are killing me with those photos of your "mouse" guns. That is without a doubt the finiest collection of little pistols I have ever seen. Impressive for sure.
Since the P11 is categorized as a "Ratgun" and not mousegun, this is the only piece I have that qualifies. I believe it is '93-'95 vintage. It has always worked fine for me and despite a few posts you can find with Google that contend that the manual safety can "slide off", mine is stiff and won't go anywhere unless I want it to. That plus the fully functional grip safety allow me to have no fear carrying one up the pipe.
