I want this for a Stoeger 2000 with a beat up chrome bolt.
Is there a difference between the chromed and nonchromed bolts (I would think none)?
Is there a difference between the M1 and M3 bolts (I would also think no difference, but I'm not familiar with M1's)?
Should I get a new inertia spring while I'm at it?
Edited to add: I have looked through the e-gunparts Stoeger 2000 section and they mention gas operation parts (like 'o-rings' and 'Gas Hole Pistol Ring #1', so I'm not sure if the '2000' model number was used on a gas gun or what.
