M1895 carbine
I have two. One Steyr, one Budapest.
They are fairly cheap, considering they are unknown and untrusted AND ammo has been a problem. Privi Partizan Unice (PPU) makes new, boxer primed, brass cases and loaded ammo. Check around for a net dealer.
It is manually operated as you probably know. The cartridge will take any game animal in the contiguous forty-eight states, and most in Alaska and Canada if careful. Does recoil a bit, but not worse than a full loaded .30-06 in an equal weight rifle.
If you cannot find the Mannlicher type en bloc loading clips (one or two will probably suffice) the carbine is a single shot. The 'clip' actually becomes part of the magazine and the carbine will not function as a repeater without one.
The issue sights are fair, made to use on enemies of the realm, not targets. Fast to use, but not as precise as others.
