To the OP, I vote for the SRT configuration if you must have a Sig.
From the sound of it, I work for the same agency as Gadfly and I am not a fan of the 229DAK to say the least. I am not alone. Most of us bought G26s when they took away our G19s. Our qualification scores went down on the easy qualification course. Many of our female agents or males with smaller hands have trouble shooting the 229DAK.
The DAK trigger is an administrator's/lawyer’s delight … heavy and long. The older agents who shot revolvers back in the day don’t seem to mind the trigger but the younger folks seem to prefer striker fired guns. On the plus side, the Sig is accurate as hell and the DAK is smooth (heavy and long with a long reset... but smooth). However, in the modern area of polymer pistols, the 226/229 is a thick boat anchor and not fun to carry concealed.
I carry the G26 everywhere and the P229 stays locked in my filing cabinet in my office. On quarterly range days the 229 comes out of the office when I qualify and then gets locked it back into the cabinet.
On scheduled enforcement operations policy requires the P229 to be carried. So it goes in the lockbox in the car and the G26 gets stuffed with G17 mags.
Word on the street is that the powers that be are opening up the list of personally owned weapons due to the strong dissatisfaction with the P229DAK in the field.
If that doesn’t happen shortly, I have a P229 with the SRT that I recently purchased on my own dime. I greatly prefer it to the DAK but would dump it in a heartbeat for a M&P or Glock if the policy changes.
