I recently jumped on the Classic LEM USPC deal. At the same time, I bought the Match hammer spring, Match sear spring, and LEM hammer axle. I went to install the parts last night and noticed the stock hammer spring is painted red, and not blue as I expected.

I can't really tell a difference between the red spring and the match, and if anything, the match feels heavier. I can't find information on the red hammer spring so does anyone know how many lbs. the red spring is?

Thanks in advance and apologies if this is answered elswhere. If so, I couldn't find it.

I'd bet the red spring is a 12 or 14lb spring vs the ~10lb of the match spring.

I did this same swap when putting in the solid hammer axel on this same gun and while the break once pre cocked (slide racked) seems very similar a totally un cocked trigger pull (fired no slide reset) is lighter with the match/standard compact spring in place than with the red spring.

That's unfortunate. By the responses, I take it that a red hammer spring is not the norm. Classic said these pistols were from an EU LEO contract gone bad that they opted to purchase and import. The pistol is not a standard configuration (LEM with an ambi safety) but I would have expected the hammer spring to be standard.

The hammer spring really on comes into play a second strike situation. The TRS , the FPBS , and the hammer rebound spring are what determines the pull after the hammer is cocked.

I was surprised at how decent the trigger is. Coming over from a SIG 226 and CZ SP01, both with trigger work done, I was expecting it to be mediocre with all the internet chatter about "overrated" HKs. Sure, there is some room for improvement in sear engagement, but as I intend this to be a HD/Winter Carry, I'm not doing anything other than install the match sear spring. Even that is totally unnecessary.

This is good news! Especially because that is all that I ordered to put into mine . Really looking forward to actually seeing the gun in person on Monday!!
