This would apply to the Revolvers that get shot on a regular basis. If your Revolvers have a Firing Pin that is attached to the Hammer then I'd look for a spare Nose & Nose Rivet. I'd also look for a standard & oversized Hand & Spring, a few different weight Rebound Springs, Side Plate Screws, Strain Screw, Cylinder Stop and Spring, and an extra Screw for the Grips. Depending on your financial situation, the next level of parts I'd keep on hand are replacement Hammers, Triggers, and maybe an Ejector Rod - although most times a bent one can easily be straightened out. These should cover many of the commonly lost, worn or improvement parts replacements. Remember, sometimes a small screw, spring or part simply gets lost - and while you may eventually find it, you want the ability to get said gun back in working order.
The great thing about procuring these parts is that even if you never need or replace one, they will only get more valuable and will probably be a better investment than money in the Bank - LOL!
