So I checked four of the Perazzis, one MX8, two Mirages, and a MT6, and a 682 Beretta. All wearing their original factory fitted barrels. On every one the barrel shoulders (barrel flats) solidly engaged top of the action walls (action flats). The 682 has a replaceable block in the barrel shoulder at the breech end to accommodate wear. Those blocks as well solidly engaged the top of the action walls.
Someone best be getting those two manufacturers informed about how to do things the proper way.
The thinnest feeler gauge that I have is 0.001" and the action of my GR3 will not close if that is between the flats at the breech. It will also capture a human hair. What a POS. Looks like Beretta can't fit a SxS either.
I appreciate all of your comments about the fitting stuff. Gotta tell ya that I'm pretty disappointed in the quality of the factory work on my guns. Not even going to check the others, they're certainly just as crap.
