Hi Folks - Looks like I got some additional CS45 questions. 
Some time back I was emailing a guy who had new 3rd generation 45 acp 8 round mags for sale that he said would function in a CS45. I can't recall which pistol model (4506, etc) they were from. He did caution to use them only for range use as they may not be 100% reliable for SD and I can't remember why.
So my questions are as follows:
Thanks and cheers!

So my questions are as follows:
- Does any one use extended mags in the CS45?
- If so which model(s) pistol are they from?
- Would you say the 8 rnd mags are reliable to carry as a spare for SD?
Thanks and cheers!
