1915 Stevens 520 inertia Question?

[Dan101955]

I own a Stevens 520 break down that i absolutely love shooting. I have a question about the Inertia block on this shotgun. Is the inertia block part of the breech block of this shotgun.
I have shot this shotgun many time and it cycles great. Kicks like a mule. I would like to replace worn parts. Have seen the u tube videos on this gun. but can not find any info. on the inertia block for this shotgun anywhere. any help is appreciated.

Not sure what you mean by inertia block, but Gun Parts Corp and Ebay has parts listed.

The 520 is a Long Recoil action, not Inertia. I’m not sure what an Inertia action is, but it’s different. Currently offered by Benelli and Franchi???

Wait, isn’t the 520 a pump?

Inertia block????? (No such thing on a 520)

what you want to tame the recoil of the 520 is a new “friction ring” . . . .BUT installed CORRECTLY!

EDIT: Forget ALL of this post . . . .I was thinking of the Model 720 . . . .NOT your 520, SORRY!!

I looked at the parts list in a factory catalog and there is nothing about an inertia block, I do not think these ever had that feature. I know early Marlin hammer pumps had an inertia action released added early on because of the possibility of a hang fire blowing the bolt out the rear of the gun. The inertial block was part of this and it released an action lock on recoil, if there was a misfire that might result in a hang fire the action had to be manually unlock to open it which they hoped delayed it long enough in case of a hang fire.
