Ok Here we go,
The Winchester model 1897 (or norinco copy)
have some advantages and dis advantages over some more modern designs
Sometimes it is possible if you leave the slide/pump action halfway open for the action to jam and ya have to push the bolt forward with your finger while holding the forarm still
It is really simple once you know whats going on
and it doesnt happen during normal operation
An advantage
You can hold the trigger down and pump the action and when the forarm comes all the way into battery the gun will fire.
So you can shoot it REAL FAST.
Faster that Any modern shotgun.
You can literally "sweep" an area faster that anyone could react.
Most important is the cool factor
Does this shotgun speak to ya?
You obviously like it It is an exellent weapon
The historical perspective is cool.
There is an exellent article on the Norinco 97tw shotgun in the Shotgun news magazine this week.
