i am new to this site and have the p3at. i am already learning a lot about it from this site. my question is it alright to keep it in the holster (uncle mikes) when i am not carrying it? will it eventually rust if it is stored in there? also i shot about 200 rounds or so out of it and the last time i cleaned it, there were a few aluminum shavings inside. is this just from breaking it in? i just used good gun oil for everything prior to knowing about grease on the rails and slides. i really love this gun.
