wow worn parts after 500 rounds I shoot that in a weekend competition

Hi Alan and welcome. After firing 500-1000 rounds, the springs, extractors, and striker springs in a Tokarev TAR 12MP shotgun are likely to wear out or break. Additionally, the trigger pin and safety switch may also require replacement.
Here's a more detailed breakdown of parts to keep on hand:
Springs:
The primary and secondary firing springs, as well as the action spring, are crucial for the gun's operation and can wear out over time.
Extractor and Ejector:
These parts are responsible for removing spent casings and can break or wear down with repeated firing.
Striker Spring:
The striker spring helps with firing the gun and can weaken or break with use.
Trigger Pin:
This pin is part of the trigger mechanism and can become worn or damaged.
Safety Switch:
The safety switch is a crucial part of the gun's safety mechanism and can break down with repeated use. Cheers and stay safe!
