For some reason no one wants to part with one that I may purchase. I need to be patient but I'm also old!
HA! I know how you feel!
I bought my CS-45 a couple of decades ago, direct from S&W as a replacement for a gun I blew up (long story). A few years ago I found myself carrying 9mm pistols and I decided I should have a CS-9. In a discussion about these guns I expressed that desire and a lovely member of this Forum turned me onto a North Carolina Forum where he had observed a CS-9 for sale, Voila! I bought it forthwith.
You might post a WTB message and see what happens but it's a pretty surefire bet most guys are not selling them.
My CS-9 had ejection problems. Springs have been replaced and it awaits a day at the range before it enters the daily carry battalion.
As an aside, however, let me make a comment about accuracy.
When we all go to the range we all pride ourselves on our accuracy skills. We practice groups at various distances, etc. And I'm the same as everyone in that respect.
However, after I satisfy myself on my accuracy skills and the guns' accuracy in my hands I always train to point shoot. I like tight groups as much as the next shooter but I'm old, too, and I don't want to rely on aging eyes and arthritic anything if I am subject to finding myself in a gunfight situation. So I point shoot. A lot. And I'm just as proud of the results as I am with tight groups, maybe more so, because my point shooting will save my life, not my target shooting skills. Jus' sayin'. I don't argue with experts and law enforcement shooters but what works for me when the chips are down is going to be point shooting. YMMV as always.
