I've only had my CW-9 for a few weeks and just hit over 200 rounds, no problems that can be attributed to the gun...My favorite carry piece now!
I tried a couple holsters and found a great unit for IWB. The company is FOXX Holsters, the product is made well, fits the pistol like a glove and it a pleasure to wear.
It saved me about $20-$30 over the "big" name brands for the same functionallity and quality.
I'm recommending both items to my "brothers in arms".
