i've read in the forums that with the available hammer sets like those from Extreme Engineering, Koenig, Brazo's, Dawson, etc. the trigger pull can be set down to a safe, reliable and consistent 1.5#!
personally, i'd prefer a smooth, clean break with a relatively heavy pull (2.5-3#) rather than one with a super light trigger pull but the hammer release feels uneven and twisty.
