I'm intrigued by these as well. I know the M2 doesn't require a take-down tool like the M1 did, so the M2 is definitely the way to go. The gas recoil system works really well according to a number of YouTube videos you can search for and watch. The gas system means the gun will get hot, but it's not the kind of gun IMHO you'd use for an extended range outing anyway. Accuracy is reported to be very very good, and Walther ergonomics are second only to CZ. Don't expect the trigger to be as nice as the PPQ, but that's not necessarily a bad thing for a CCW. Field strip and re-assembly is a little different, but I think easy enough to get used to after a couple times of doing it.I'm thinking about buying one for the wife.
You haven't read much (about the original) then. LOTS of gripes on the Walther forums. Several documented issues. Lots of long threads about what went wrong and how to fix them. seems a good portion work fine or go to owners that don't know better but still a LOT of problems for a production gun. I have one. I really want to like it, I do like a lot of things about it. Unfortunately it's conceptualized by upper management and designed by interns. there are a couple mistakes in the design that are just "oh duh" mistakes like not cocking the striker until AFTER the slide is far enough back to load another round and no tolerance behind either for overtravel meaning to function reliably, you have to batter the frame and there's a small range of travel that it's possible with a light load that it can conceivably load a round without cocking the striker (Literally every other gun I've seen cocks before cycling the action enough to eject or load another round.I have the original CCP then bought the CCP M2. They are both very smooth shooters and have exceptional ergonomics. Other than some grips about needing a tool to field strip the original, I've not seen or heard any complaints about the CCP (especially the M2). It's a great choice for a carry pistol.
The gas system will do that. As much as I criticize it, indeed it does shoot well and feel fantastic.I thought the first gen ran pretty dirty compared to other handguns. Shot good though, ergonomics were great.
