Sig P320 problem. Slide doesn't cock trigger

[BattleReadyBunny]

I've seen this sear stuck down too low on customer guns when they fiddle around with their FCU

This would cause it not to catch the striker's tab. Make sure it is sitting at the correct height in the resting position and make sure it moves freely.

I meant "upgrading" the gun from its stock configuration by adding "go fast" etc parts. Not the upgrade dirty carry was talking about.

Suuuuuuuuuuuuuure ya did...

If he was really going to upgrade it, he'd have traded it for a CZ.

Since it's a used gun I wonder if it got sent back for the upgrade.
The part's he added I'm sure are made for the upgraded version.

Actually it's a new gun, recently purchased. Has the upgrade. But thanks.

Please forgive my ignorance. I have a new P320; it worked fine before I performed the following mods: Norsso slide/bull barrel and an Apex trigger bar.
Now moving the slide fails to cock the trigger. It might be a simple problem, but I'm at a loss.
Any help will be appreciated!

It's no longer a sig, it's a frankensig.
