I picked up my model 12 today.

they are factory proof marks, there stamped after they fire proof loads.
Model 12's are still going strong but there are some things that need to be checked to see what condition the gun is in, how much wear and if the locking surface is starting to roll.
Bolt lock-up, timeing of the lock-up to firing, barrel to receiver fit. It could have been carried more than it was shot or it could be worn out and in need of rebuilding.
If you have any question let me know or do a search for m-12 issues and repairs.

Wow, I can think of no better expert on the model 12.


You've got a great versatile shooter there and you saved a chunk of change by having a polychoke on it.

IMHO, I think you did fine. The Model 12 is pure American history in any configureation and therefore a collectors item. I own two, a 12 & a 16 both with 28" modified barrels. The 16 was made in 54 and the 12 was made in 62. I'm sure they will outlast me. Do you plan on keeping it as is with the poly-choke? Congratulations on owning a piece of History.

screamin eagle, yours looks almost exactly like mine - right down to the polychoke! Looks like you've got a keeper (just like mine).

I have a duck hunting buddy that has shot steel through his model 300 with a factory variable choke for years wit no obvious ill effects. It is an un-vented style like yours and he never adjusts it tighter than modified. I say go for it.
