Hey all,

Bought a Sig P320 sub-compact about six months ago. I want to put an Apex flat trigger in it, and come to find out, it has to have the voluntary upgrade for the trigger. What's the easiest and fastest way to see if its had the upgrade? Thanks!

Send a photo of the underside of the slide. It should have a small divot milled out to the side of the striker.

Also it should have the thinner trigger.

OK Thanks! Looks like mine has not been modified. I only want to replace the actual trigger, and not the entire trigger assembly. Do you suppose I can get away with just swapping out the factory trigger with the Apex flat trigger?

If it was new 6mos ago, it's probably had the modification from the factory & probably has the finish vs the bare metal of modification of guns sent back to sig.

A lot of dead pics thanks to photobucket, but look at new vs old here.
