Comment on the list of failures above.
My breechblock failure was atypical. You've seen the pictures. There was a sliver that parted from the side of it. The common fail is the breakage of the rearmost tip that does away with the striker retainer slot rending the pistol inoperable (what happened to mine didn't). This generally happens when by excess of headspace the primers get pierced, the more common cases I've seen (and I've seen or heard of some 4 cases) happened with .30 Luger pistols that used ammo with the bottleneck set to far back. Some folks say that Fiocch ammo is underpowered and causes jams. When getting malfuntions using Fiocchi ammo my advice would be to check if there are pierced primers. If so don't use that lot of ammo in a Luger, there will be no big problems with conventional Browning type actions(besides poor accuracy
) and the fired brass will be correctly fire formed to the chamber and be quite safe for reloading.
