Hello everyone!
I guess this is only place to find a good help.
I have got problem with NOVA hammer in my TM M.E.U.
NOVA Kimber Type Hammer & Sear Set
Product No. TM-GMP-U01-SB
Here is the hammer photo:

(for my Custom - Kimber Desert Warrior)
1. Then it's installed - Grip Safety don't work (i can shoot even don't press it).
2. Sometime hammer stop on half way and no shot at all.
If i'am install original hammer (TM M.E.U.) - everything is O.K. (no both problems).
I have found small help with remarks from Anvil:

Maybe it will work properly with Nova Grip Safety (i am using now HurricanE Grip Safety - it was in Kit)?
Or better buy new hammer from PDI (Koutetsu Oval Hole Hammer) with PDI sear (QPQ SEAR)?
