the model 1891 is my personal favorite. I like the long, elegant rifles from the 1890's time frame. that also includes the m24's, as they are basically just modified m1891's.
not necessarily the most accurate, or best handling, but by far my favorite.
y'all have a good day, Keith
Ditto what Keith said. M91's are my favorite. You can see it is the direct descendant of muskets and black-powder cartridge rifles. The lines, length and features (especially the earliest M1891's) just intrigue me. Plus, the M1891 represents the start of a LONG line of Mosin Nagant variations that saw service across much of the world, and continue to serve even today.
My favorite Mosin-Nagant rifle is the M91/38, I like the older rifle markings combined with the handiness of a carbine. I've also got an interest in Czech firearms (Nazi modified Vz-24's are my favorite Mausers!), so the Czech connection is there for me as well...
The Polish 91/98/25.
It's what the kids would look like if a Russian 91 rifle married a German Kar98k.
I love the mix and match quality to it, all the struck out and restamped serial mumbers, and the way the Mauser front band and bayonet lug look on it. The end result is a handy 98k length short rifle, in 8mm Mauser, well made, that's at the same time something of an odd duck and which always attracts attention.
