My girlfriends S/42 1936 with a very very pitted bore shoots with swedish subgun ammo 2" groups at 25 meters.
THe bore is so pitted that you can't see any difference betwen groves and lands.
My own gun with a heavy custombarrel shoots within an 1" at 25 meters, both with jacketed and lead bullets.
In my opinion the Luger pistol and the SIG P210 pistols are the most accurate pistols ever massproduced.
