This was most of my ownership, if I couldn't fix it, or get the parts it went back. G2 I only had the trigger issue, rest was random parts and unfinished slide dragging against the barrel in 3 places.
Crazy part is that gun sold for more than I paid for it.
If you really one one, be prepared for fun times if the pin walks and cracks the frame. The serial number is not on the frame but they still treat it that way and won't send you a new one. The CPX2 G2 938 and 605 are all pocket guns for me. When I looked for Smith pocket guns they run $1500-$2000 because they are super rare Performance Center guns and or had Lew Horton papers.
