I bought a 4046TSW today, Serial # Prefix TDU8XXX, DAO.
I thought I'd be nice to the gun and strip it down to clean it and when I removed the one piece plastic stocks I got a surprise that I can't figure out where it came from but I now have a small, stout spring to figure out where it goes!
The photo shows how small it is; I've looked at several online schematics but can't find that spring anywhere! Thanks all!
When I was working my way through school, I had a job in the maintenance department of a good sized company. One of the painters had a disassembled spray gun soaking in solvent and one of his buddies dropped in an extra part. Had the painter baffled for weeks.
Sorry I can't help. Looks like it could possibly be part of a broken firing pin spring, but I can't see how it would get out of the slide.
It may well fall under the "extra" part...I had knocked a box over two days prior and the spring may of came from that box...which further baffles...where did I it come from then!
