Yeah, I was checking that out and will likely go that route.Or, look at TooSixy's spring chart in the Reference Section, order the exact type of springs you want, for a light, heavy or TLG LEM, from HKUSA for a lot less $ than other venders and install LEM yourself. Links to Youtube "How to" videos if your search on this site.
Easy to do and you'll learn alot about your firearm. P2000/P2000sk, killer pair of firearms.
I did it with one punch at my desk in an hour, including time spent watching the videos. I have zero gunsmith experience. It's just not that hard.
Sorry for the unwanted advice. Seems the cost would be less than shipping and FFL transfer. YMMV. Hope it all works out for you. I love my LEM triggers. PM me if you have any questions.
