When I was doing coding and would give my wife and estimate of how long before I came home this was her formula for figuring the actual time it would take.
I'm rearranging my competition guns and decided to trade in one of my S&Ws revolvers. It had an apex hammer and springs plus I'd plugged the Hillary Hole. Of course I put the original hammer, strain & rebound springs back in. Easy Peasy. Then I decided to put the Infernal Lock back in and save my plug for another gun. The gun I've replaced this one with is a pre-lock model, btw.
Well that was an hour long job to do just the lock. Little parts and springs flying everywhere. Thank God for magnets. When I finally figured out the technique for putting the stupid lock back in, got it all assembled, all buttoned up, no single action. Oh duh, test before you put on the side plate stupid. The hammer is different between lock guns and non-lock guns. (yes I have a number of spare hammers). Open her back up again swap out the hammer.
So finally ready to sojourn down to the LGS. Rex G7 458 silencer? Or maybe a PCC? Or just put it on account for ammo?
Oh, and did someone say they wanted my ~1976 era Charter Bulldog .44spl? It has one branch of the extractor broken off, just the end. Still extracts just fine. Looks ugly.
