Sig lists the DAK trigger pull at 6.6 lbs. I would expect the DAO only version to be over 10 lbs. As I said the DAO version is primarily produced for LE where administrators have decided that a long heavy trigger pull is needed.
As Rivalen stated Sig DA/SA frames are compatible with DAK parts. I believe that you would be safe with any frame made after 2006, though as he points out it may be hard to find the parts in Canada.
Speaking of the OPP I was talking with an officer who said that they are switching to the 229R. I presume that Sig no longer wants to make the non-railed frames or that their contract is up. He also said that they may be DAK's but he wasn't sure. He did say that they will not be issued lights for the rails or a holster that would accomodate a light.
Still though if they do adopt the DAK trigger system that would be a big improvement.
In my opinion, there is no reason for DAO triggers to exist but to satisfy the white shirts and pencil pushers.
