OK.
Well I also grew up shooting DA revolver, and still didn’t care for the DAK trigger. You might like it, but a good DA revolver still beats it I think. There might be gun smiths like Bruce Gray that will slick up the DAK trigger and make it better though.
As for shootability I’d go for the P226 over the P229, particularly in .40 S&W. Now that both pistols use a milled from billet slide the P226 is plenty durable for use with the .40 S&W. The grip is easier for me to get along with on my P226 X5 than the P229 was. Recoil between the two was never an apples to apples comparison though since my X5 is a 5” heavy barrel, all stainless, hand fitted match gun... so yeah it tracks flatter under recoil.
My old P229 was accurate though, particularly the .357 SIG barrel. Just wasn’t a trigger I could shoot well at speed, first shot was usually on par with other triggers (in fact a DA first shot let’s you get on the trigger way earlier when driving the gun out to the end of presentation), but finding a good rhythm for something like a Bill Drill never worked well for me. I suppose it’s a training issue, but when other trigger systems offer the safety and forgiveness of a DA first shot and the sweet easy to shoot well and shoot fast SA for subsequent shots I’d rather devote training time to a DA/SA.
Of note the Exeter made SIG’s made under the Cohen reign of mediocrity at SIG aren’t what they used to be quality wise. They don’t stack up to the German made guns from what I’ve seen. I’m by no means a proponent of the idea that all new guns are rubbish, or German made guns are better... but in the case of Cohen era SIG’s I would be cautious.
