I've been very lucky with Mosins, and got into them more by accident,
than on purpose.
The tone got set by the mint Polish M44 I started out with.
All matching serials, of course, and never fired, to boot.
The Russian M44 was also nice, but the 1925 Izzy was another
stroke of pure luck.
It started with the usual "search through the pile", where I turned
up a completely matching '34 hex Tula, and asked my FFL to hold it for
me. He wound up selling it to a mutual friend, and I got first dibs on the
next shipment. The first rifle out of the box was the 1925. Apparently
re-arsenaled in 1930, it's got the hooded sight, and the new stock
and barrel bands. Still a nice gun, with solid rifling. Also very accurate.
