The DA pull is designed that way as a safety. If I remember the A1 uses the DAK (red) mainspring. I'd try the normal SIG mainspring and see if that helps.

Depending on your skills, you could polish the trigger bar where it makes contact with the hammer, and grease the contact points. I wouldn't go lighter than a 19# mainspring, for reliability on a carry or defensive weapon. From what I understand, they have used a heavier than normal mainspring, in those for some reason, as some other members have reported.

Two words: Robert Burke. He did my 225 A-1 and the trigger is much better all around.

Yes, red.

The newer ones are shipping with lighter springs. The standard M11 (short) hammer spring does a nice job. That was the only thing I did to mine other than shooting the hell out of it. I've replaced the recoil spring once already.

Send it to SIG for the AEP or Robert Burke or Bruce Gray. Each of them changes the mainspring to the lighter normal one and does a nice action enhancement job.

Replace that red mainspring and report back. I'm guessing that is all you need to do. Why look for any other solution when a $3 spring is all you need?

Yep^. Mine came with the regular bronze color spring and trigger is great.
