Glad you like your “new” CCP. I have the M2 version and couldn’t be happier. I have been running Winchester white box 115 grain through it when I first had it, I’ve tried several different brands and grains and the only thing it’s not crazy about is some cheap stuff we bought on line. The bullets have a greasy feel to them, so I will have to wipe off each one before use. I’ve even put reloads through it and it will just eat it like candy. I carry mine in a Vedder IWB holster and it is so comfortable I sometimes forget I have it on. No issues cleaning it either. Would like to hear about it more when you get it back from Walther.
