I say that the DA pull on my p345 is a bit long and a little on the heavy side. I have a p229 Sig right now and I spent a bit of time comparing the both and its not really that close. The SIg has a much better pull. The SA on the Ruger is not bad, the reset seems about right, not too long. Not too short. Nice distinctive click. Of all the semi's I've had, the DA is on the bottom end in terms of length and weight of pull.
The p345 does feel real good in the hand, balances well and is very slim. Quite easy to carry. I read on the gunblast.com review of the p345 that their DA pull was 8 lbs 5 ozs and 5lbs and 6 ozs for SA. Mine feels heavier on the DA but the Sa does seem close to the 5.6
