SIG P320 - trigger return spring

[sobo]

After 15,000+ rounds, mine finally broke during a friendly competition last weekend. So, exactly how difficult is this to replace? Any special tools required? Do I need three or four hands to do it? Or is it better just to take it to a gunsmith?

Eight... unless you count my dewclaws...

Super easy. I did it when I swapped out the trigger on my FCU. There's definitely tricks/tips on youtube to make it easier.

Use that trigger assembly video by Sig Guy that's been posted here.
Follow Sig Guy's tool-less method and do not attempt to use a plier.
I did the bone-headed plier thing and trashed the spring on my first attempt.

Thank you, 1775 and DD!. Much obliged!

I'm sure a civil can figure it out.

So.... How long did it take you and how many times did little springs launch to the moon?

If you've got that many rounds on it and the reset broke. I'd either refresh the striker springs. Or just buy a new one. I replace my striker assembly ever 5k or so rounds and I keep a few spares in my sig bin as well. Same as the sear springs. Refresh them every couple thousand rounds and you're good to go.

I took forever getting around to ordering the new spring (and a guide rod assembly while I was at it), but they arrived at the beginning of December. I let those parts sit around a bit while I reviewed the SIG Guy video above, helpfully posted by @1775usmc. Then, I set about to replace it one night a coupla weeks ago, before Christmas. It all went together in less than 5 minutes, success the first try, with no springs launched into low earth orbit. I was quite satisfied with the results.

I should probably do that next. Thanks for the suggestion!

Can't be any worse than an HK P30. Seriously, that's my new standard PITA gun part. I hope to never, ever do it again but I special ordered the necessary pliers anyway. Two punches, some tape, a lot of cussing and a small screwdriver finally got it in there. With a bunch of finish marring where nobody will see it.
