To replace this one with the gun assembled. I tried it once before on my compact, but could not hold the spring int the correct position and get a slave pin in. One poster to this forum claims to be able to do this in a few minutes - not for me!
The biggest problem here is that I hate dealing with the safety (even though I'm much better at it now), and the trigger pin itself. On the PreB it is a double tapered deal and EASY to drive in/out, but I think if I end up doing it too often, it will eventually get too lose. Darn.
BTW: I bought a few trigger springs back a few years when I ran into the TWO P01s and their broken springs. It was a BAD TIME to buy springs! The 2-3 I bought all broke within a few hundred pulls of the ttrgger. This PreB went through thousands of pulls with an '84 spring before it broke! This last one, like I said, had probably about 100.
