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.
Important Notes
• In the chart below, you may see some parts listed as
Standard in one gun but may be cross listed as
Light (green) in others. This is because for that specific gun, those parts come with the standard variant (V3 for the P-Series and V1 for the rest). For example, if you look at the chart for the HK45 Full Size and P2000, you will see that the Firing Pin Block Spring (209296) listed as standard spring on the HK45 V1 (DA/SA) but is cross listed as Light FPBS on the P2000 because the spring does not come with the P2000 V3 (DA/SA).
• For USP/HK45-series guns, if you are converting a stock DA/SA to a Light LEM, the HS, TRS, and FPBS for the Light LEM should be identical to the DA/SA springs. The chart below shows a different TRS (Light TRS) for the Light LEM because it is assumed that you are converting to a Light LEM from a Heavy LEM configuration.
FPBS = Firing Pin Block Spring
TRS = Trigger Rebound Spring
HS = Hammer Spring
