Zimmy:

Not to speak for you, but I'm thinking the Benelli was a .30 Luger, one of the models B76, B77 or B80?

They produced a fairly nice pistol in 9mm and .30 Luger and some were sold in .30 here. Evidently had some hammer-breakage problems early on. Had a sort-of Luger-like grip angle. There are a few of them floating around these parts for some reason.

The .30 Luger was popular in Italy due to the restrictions on 9mm pistol sales. IIRC, many .30 Luger Browning HP's were sold there also. .30 Mauser is essentially the same case as the .30 Tok/7.62x25 and too long for the Benelli grip frame.

The .32 S&W was indeed loaded in several autos for target use. It is a low powered load producing velocities far below that produced by the .30 Luger and even less so the .30 Mauser/7.62x25 which are very fast indeed.
