cherrypointmarime I use two holsters with the CS9. For OWB a Don Hume JIT slide, number 30 and for IWB a DeSantis Nemesis model E1.
The Nemesis was originally a pocket holster. And with a flat 3913TSW mag base pad on a CS9 mag, I have pocket carried it a couple of times. Its doable, but NOT my preferred mode of carry. I use the Nemesis as an IWB holster. And when carrying the CS9 it is what I use 80%+ of the time.
In hundreds of draws, I have never had a Nemesis holster come up with the gun. Of course, you cannot reholster with the Nemesis without removing it andputting the gun into it first.
I currently have a very kind and TALENTED gentleman making me some holsters. He made me an EXCELLENT IWB for my CS45 a few years ago. As soon as I have his permission to post his company and contact info, I will do so. I bet he could make you one for a CS9.
And as soon as I recieve and wring out my new holsters, I will post detailed reviews, here and in the leather gear section. Regards 18DAI
