I am an acknowledged fan of revolvers in semi auto calibers. I have a small collection of them primarily in 9mm and 45 ACP, although I have a 940PC that has an extra cylinder that allows me to shoot 9mm, 9X21mm, 9X23mm, .380 ACP, 38 Super, and of course .356.
I use my 940 a carry gun and as a BUG for my BHP, you can reload the 940 really quickly using a semi auto 9mm magazine, just thumb the rounds into the cylinder, of course then you will be ejecting the empties with a fingernail. On the other hand if you have not settled the situation with 46 rounds from the Browning, and 5 from the 940, the extra 5 are probably not going to make much of a difference.
The 940 is a great little gun with lots of metal around the chambers and will hold a really stout load. Some of the really strongest loads I have fired from one of mine were a couple of boxes of the old 70s era Super Vel 9mm, they really bark and flash-and recoil. I suspect they are way ahead of todays +P loads.
