I put Sig X-Series flat triggers in a couple P320's. I like them better than the standard curved trigger, but I am finding that the side edges of the flat triggers are a bit too square.

Grayguns has a flat P320 trigger with adjustable overtravel, and you can still get the discontinued non-adjustable flat one at a few places.

Anyone try these? Does either one have more radius to the side edges compared to the Sig? For reference the P365 Sig flat trigger is much better IMO, slight radius to the front face and better transition on the edges.

I have both the adjustable Grayguns triggers, and the non-adjustable flat triggers.

Where a sleeve was used to correct for overtravel, previously, the newer ones with overtravel screws are a big improvement.

I have several of the Grayguns competition trigger kits, as well, as it makes for a very nice trigger.

The Grayguns basic flat trigger, without any overtravel features, as dropped into the pistol, is similar to the Sig flat trigger. There is less takeup and over travel with the Grayguns trigger, and a shorter reset.

I have both the Sig and Grayguns flat triggers in my P365's. My preference goes to the Grayguns.

If you are after comfort, I'd look at the Armory Craft full adjustable or the Keres fully adjustable triggers.
