2nd range trip about 300 rounds through her. Like the cm9 a lot.
2nd cleaning I notice a half round cutout hole in the front part of the left guide rail (metal rail impregnated into front of lower frame ). Can't remember if it was there before - I dont remember seeing it.
Any cm9 owners are your guide rails without any such voids? It seems smooth like it was cut out. I will attempt to attach photo later I can't figure out how from iPhone right now.
Thanks
Andy
