Over the past few months, I've seen a number of people asking about what spring(s) they need to convert between LEM variants. So I came up with this chart. It lists the spring part numbers that you will need to convert from one LEM variant to another.
This is something that I have gathered from different sources over the past year and a half. I try to cover all the guns as accurately as I possibly can, but if you find something amiss, please let me know and I will update the chart accordingly.
FPBS = Firing Pin Block Spring
TRS = Trigger Rebound Spring
HS = Hammer Spring
DAO = Double Action Only
LEM = Law Enforcement Modification
• For USP/HK45-series guns, if you are converting a stock V1 (DA/SA) to a Light LEM, the HS, TRS, and FPBS for the Light LEM should be identical to the DA/SA springs. In other words, keep all the stock V1 springs. The chart below, however, shows a different TRS (209266 instead of 214164) for the Light LEM because it is assumed that you are converting to a Light LEM from a Heavy LEM configuration, and not from a V1 (DA/SA), but either 209266 or 214164 can be used.

Nice job TwoSixy! You've always been the trigger variant guru around here.
Mods, this looks to be a valuable sticky!

I've noticed that the 209 266 Trigger Return Spring is marketed by HKParts.net as a light LEM option for P30, P2000 and HK45..
Very nice work TooSixy.
A lot of work, this should be an updated reference sticky in the library.

9And he said unto me, My grace is sufficient for thee: for my strength is made perfect in weakness. Most gladly therefore will I rather glory in my infirmities, that the power of Christ may rest upon me.
