The apex and sig flat triggers are quite different in appearance, and feel different on the pistol. I have them both on the P320.
I haven't seen an Apex flat trigger for the P365.
The flat trigger places the finger farther from the fulcrum, allowing more leverage on the trigger, and the illusion of a lighter trigger. Both the sig and the apex triggers (and the grayguns, which is essentially the same as the sig) trigger for the P320 have very little overtravel, and all three claim reduced takeup, though that's not appreciable. The apex uses a spring loaded overtravel stop, and the kit uses a slight change to the trigger bar also as a stop. Grayguns and sig advertise that their flat trigger stops at the vertical, or 90 degree point, if that's important.
I like them. I have replaced the triggers on my P365's with both sig and grayguns flat triggers, and on my P320's with sig, grayguns, and apex triggers.
I think the flat triggers are fantastic, I have them on four of my sigs right now, and picked up a new P365 XL today, the flat trigger just feels so much better to me, and for me, when I'm comfortable with my trigger, my groups tighten, and I like that, I hope Sig starts putting these triggers on all there models...

The Sig flat trigger appears to be a stamping from a flat piece of aluminum or sheetmetal therefore it is open at the back. If you want to check out the look and feel, see if your dealer has one of the newer 365XL models in stock. It comes standard with the flat trigger. Grayguns advertises that their trigger (almost twice the cost of the Sig), is made from barstock so I presume it is solid.

They're indistinguishable in performance. Slight aesthetic differences, perhaps, but they feel and operate the same to me.
The Grayguns trigger extends down slightly into the trigger guard area before angling forward, while the Sig offering angles forward almost directly. The slight forward hook angle at the bottom of the trigger has a bit less pad that the Sig model. Both are "hollow" or concave at the rear of the trigger, in similar appearance to the P320 "adverse" triggers.
Sig's flat triggers have a small extension forward of the trigger on the top end where it passes through the frame, which fills the gap in front of the trigger. The Grayguns triggers do not. Other than that, they appear nearly identical in geometry and from an eyeball view. I didn't apply any instrumentation to them for the minutia, and that may be where the difference lies.
I just installed the Sig flat trigger on my 365. The install is not for the faint of heart. It's not super complex, but more complex then say changing out your Glock trigger. I managed to do it in about 30 minutes with the help of a youtube video. I like it overall. I recommend it for anyone on the fence.
Well I ordered the sig flat trigger($34) and installed it in my 365, was fairly easy. It felt weird, but better. I really liked the curved trigger so I reinstalled it, it felt awful! Put the flat back in, and its just right.
Ordered Apex flat trigger for my 320, see if it does the same for me.
GGI trigger for the 365 is $79 IIRC, that's just ridiculous.
Put a Sig flat trigger on my Sig P320 Tac-Ops and loved the look and feel of it. So I recently purchased the last P365 flat trigger on the Sig factory website. I watched the YouTube video to help me install it. Much harder to install than the P320 flat trigger but doable. Again, love the look and feel, can't wait to take it to the range.
