The Stevens wasn't made very long. Maybe 3 or 4 years in the late 40's. Then the Savage 340 came out in the very early 1950's to replace it..

A few changes to it, especially the bolt handle, but pretty much the same rifle.

Model 340 (30-30) mags can work but you usually have to file the mag body stops to allow them to be seated just a bit deeper.
