Hi Rick, I think on the average, wolfe springs are pretty good replacement springs? But, I'm not familier with their trigger spring?
The three most important springs in a Luger are the mainspring, the extractor spring, and the magazine spring.
The rest don't seem to have any extreme demands put on them? The sear bar spring might have something to do with doubling when weak, but for the most part, if it's in there, it's probably working! ... Best, til...lat'r....GT..
