The Sig 229 you ordered is probably as good a choice as any. You can change out the hammer spring on it to lower the DA pull. Or you could send it to Robert Burke, The Sig Armorer, to do a whole number on it.

The HK P30 series is pretty decent and is easy to do a hammer spring swap to lighten the DA pull a couple of pounds. I’m not a fan of their curved trigger, but the DA/SA is pretty good. They also do a LEM (Law Enforcement Module) trigger, which is kind of hard to explain, but is a long, but very light Double Action only pull. It is designed so that it can’t be accidentally pulled because of the length of the pull. A lot of HK folks swear by it and I can say that once you get used to it it is pretty nice.
I recently picked up a CZ P07 which is comparable in size to the 229 which has a 10lb DA pull and a 5.5lb SA pull. I installed an MCarbo trigger kit which significantly reduces both. It is a great gun and I have put it into my carry rotation.
