I've been thinking of picking up a P-26

Hes asking about $400-  it's a very low number 1XX, everything looks appropriate for the range, cut stock, and it has the barrel blank(?) that you can see.  I seems like it's in good shape but I'm nervous about it

I want a Finnish Mosin but the barrel liner makes me think this isn't a shooter? Im not looking to blow through thousands of rounds but I don't want to blow up a historic gun either

should I go for it or wait for a more traditional gun?

That is a good price for a P26 marked gun, they go for more than your run of the mill Finn Mosin.
