the exploding russian guns were usually auto loaders chambered in 7.62x54 (a russian 30.06 basicly) the problem was soft non military primers in domestic loadings, the military primers in russian ammo are built with a much harder metal cup, as the bolt slams forward into the case inertia carys the firing pin into the primer, with the soft primers there was a chance that the round would detonate out of battery (before the round is fully chambered and the bolt locks) which is a bad thing. i have not herd anything bad about russian pistols, now japonese pistols are dangerous and shitty, had one with a split barrel that didnt look like it had a dozen rounds (luger looken one can't remember the type) and that little black bastard with the exposed sear (can and will fire with the safety on with very little pressure to the side of the receiver above the grip). ps they usually fixed the 7.62x54's with the addition of a spring on the firing pin
all america wants is cold beer warm cat and a place to take a poop with a door on it
