I recently paid $390 for a new Model 94, 20 inch barrel, in .45 Colt caliber.
Sounds like the Trapper you saw is used.
So, I consider it an ok deal, but not a great deal.
Based on what I've seen here on the forums lately, some Model 94s
have been going for as much as $600. This due to the fact Winchester
has shut down I suppose.Generally speaking, the model 94 is a
reliable rifle. After all, they've been in use since 1894.
The only con might be the 16 inch barrel in .30-30 caliber.
Specifically, the muzzle velocity will be somewhat less than a 20 inch barrel.
