Congrats on finding one. Especially in CA!
Some years back, before I retired from Investigations with the D.A.s office, I scored a nice condition 3914NL. It is a very ASP like pistol. I consider it to be the direct descendant of the ASP. I carried it on and off duty and into retirement. I still have it, but it is seldom carried or shot since I got the CS9s.
I have an early black CS9 - which will be going to BMCM for night sights - that I have shot and carried some and a stainless which I carry pretty much daily and shoot often.
I think these CS9s are what the original ASP aspired to be. Small, easy to carry and conceal and VERY fast into action. I had occasion to point the black CS9 at a miscreant a couple of years back in the court house parking lot. Afterwards, I realized just how fast that gun went from an IWB holster, concealed, to pointed down range and "ready". Sure made an impression on the miscreant. He remembered he had to be somewhere else and fled in a hurry.
If you don't know, Ken Null holds all the patents from Seventrees holsters, which was Paris Theodores company originally. Mr. Null makes outstanding holsters. He still......well, as of 4 years ago, makes all the original design ASP holsters. They are not inexpensive though.
I had him make me one for plainclothes use for a 3913. Best holster I own. If you get the ASP, you should contact him and get some of the original design holsters for it.
Good luck!
Let us know if you score that fine nine! Regards 18DAI
