I feel like a total idiot.
I was field stripping my Llama .45, with a view to installing a beavertail grip safety.
The damn safety-slide stop spring plunger assembly shot out across the room, whilst I was reassembling the damn thing.
To add insult to injury, the last plunger set in my oops kit must have went into a friends pistol.
Ironically I should have reordered a dozen when I was down to two.
Ironically additionally I can't find mention of an oops kit anywhere on the internet.
Anyone I ever spoke to knows what an oops kit is.
Another argument for a reasonably clean room.....
