I just got a set of springs for my LCP from Wolff, an 11# recoil spring and a firing pin spring. I changed out the recoil spring, but is it worth the hassle changing the firing pin spring? Looks like a bit of a job.
Once you've done it a few times it's no big deal. If you haven't done it you probably need to anyway because the firing pin and extractor tunnels get caked with gunpowder.
The big thing for first-timers is to be aware that the spring will launch the firing pin across the room or into your eyeball. Until you get the hang of it, depress the firing pin with a matchstick (I use the blunt end of a wooden shishkabob skewer) until you can push the firing pin stop partially up. Then put the slide in a gallon size zip lock back and push the firing pin stop all the way out letting the bag catch the spring & pin. That's for series 70. Series 80 is a bit more complicated but still easy -- and still necessary.
EDIT: Oops, just noticed you've got an LCP. I've never taken one down, so my technique may not apply.
As mentioned it really isn't hard at all. Just take your time and be sure to have something to catch the firing pin and spring in case you slip (I always recommend doing such procedures for the first time with your hands inside a one gallon bag the first time as it does a great job catching things). Once you have done it once it will be a lot easier. Any job worth doing is worth doing right and if you don't change the spring you'll always think you should have.
