Nicely done!
Recieved this kit, along with the flat trigger and the peepless folding latch/charging handle kits this afternoon (9mm versions). Installed and everything function-tests well. Not a very fun gun to work on, but it all functions properly. Trigger pull went from approaching 8 lbs to closer to 4 lbs. Very nice improvement. Didn't want to bother the neighbors since it was after dark when I finished but I'll try it out soon. I left the over-travel screw where it was (if that is what that little allen head on the trigger actually is). I may break it down again and snug that just a touch, but it feels a ton better already anyway.
Is this spring kit compatible with your FPC flat trigger?
Yes — the Smith & Wesson M&P FPC Trigger Spring Kit is fully compatible with the M*CARBO FPC Flat Trigger. Both are designed specifically for the S&W M&P FPC 9mm platform, and they complement each other perfectly. The spring kit reduces overall trigger pull weight and smooths the break, while the flat trigger improves ergonomics and consistency. Installing both together gives you the best overall improvement in feel, control, and performance.
