Just picked up a new MP22 compact. Love everything about this gun, but noticed one thing that I didn't expect. The bore is, well, rough. Granted, this isn't a match gun and I didn't expect a mirror finish, but the first time I looked down the bore, I thought it was rusty. But closer examination shows the bore, both the lands and the grooves show what appear to be machining marks. Just wondering if this is normal for this gun. Are there any other MP22 compact owners out there who can relate what their's looks like?
