Kahr just released this week a CM9 which is a PM9 with a few less bells and whistles. It is the CW9 in a PM9 oackage. It is a new release like the LC9 is and neither have a long track record. The PM is a rock solid weapon and a great gun, I also own the CW9 Kahr so even though I don't have a CM9 I have its 2 closest relatives and would not hesitate for a second to recomend anything 9mm made by kahr.
The LC9 seems like a real winner too, I have held one and like it, in this case however I would go with the Kahr. Now this only my opinion and is not meant to be taken in any other ofrm then my opinion.
The Kahr CM or PM9 are both pocketable light weight thn and can be carried easily hidden all day long. There are plenty of very good holsters available for the Kahr and it has a very reliable customer service department.
Ruger has also got very syellar customer service department and I am sure there is holstere=s and gear on its way to market for the LC9. It too will hide and carry easily.
