I was having the same low and left issue prior to installing the Apex trigger. I have noticed my accuracy increase with flat triggers in my 320 and AR. I must do something funky when shooting rounded triggers but I think I am sold on the flat triggers from here on out.

I was posting in a thread about this low left but I can't find that thread now and this is the most recent I found on the topic.

Did you go for the advanced trigger or standard? That's my debate right now, if I decide to change the trigger. I haven't tried a flatty, so I won't know until I dish the $$ for it.

I fought with low left, and went 700+ rounds trying to see if it's all shooter error. My front sight was to the right, but I thought it was sighted at the factory and made no changes before ruling out shooter error. This is what it looked like:



I called Sig this morning finally, they suggested shooter error. They said they "install the sights and 'eyeball' it," but they later said they sight it at 10 yards (I thought I've read in the manual or else where it was sighted 15 or 25 yards).

Regardless they said to drift it so I did. Regarding the LOW issue, people said this was resolved by the front sight. Mine is a #6, and supposedly too tall and if replaced with a #8, would resolve the shooting low issue on my 9mm compact.

People said "call Sig they'll take care of you" and "Sig sent me a #8 front sight today" etc... Though I didn't demand anything from them, they told me they'd have to take it in and shoot it obvi and said it'd cost $100-130 (forget exactly) for ammo and testing I guess. 4 week turnaround. If it was under warranty then wouldn't charge? They were more keen on giving a charge than saying they'll take care of me.

I chopped up a wooden dowel, flattened one end of it, drifted it to center-- I'll shoot rested at various yards to see how it goes.

This is AFTER. I don't have 20/20 but this was to me "eyeballed"



I'll see what it does shooting rested.

This was with sights unadjusted, shot rested at 5 yards (P320 is on the right). IIRC it was about 1" maybe 1.5" LOW LEFT.

I know pistols should be zero'd at 25 yards or 15, and that an 8 vs 6 front sight would be a 1 or 2" difference at 25 yards, but I chose to do 5 yards because this is my only pistol I can't consistently hit steel plates estimated 6" at 10 yards so if it's that off at 10 yards, it probably wouldn't even show up at 15 or 25.

This has been hashed over numerous times, for some reason Sig starting installing the 6 front sights on the compacts. i have 2 320's compact 9mm one early 2015, with a #8 front, and a recent 2017 build that had a #6 front. The 2015 one shot perfect, the 2017 shot low. I replaced the 6 with an 8 and all is good again.

As far as centering the sight, the best way is to center using the side of the slide rather than those machine cuts. I have seen those cuts, off on some 320's. What I have found is the 320 is very touchy when it comes to sight adjustments. It doesn't take much movement to adjust the sights POA/POI.

Once your sights are centered and height regulated correctly, it should be able to print like this is 15 yards all day long, and this is unsupported, with factory fire controls and trigger.

Right, and that's what I expect when opting for the optional Siglite sights. Had I known I'd have to be changing sights or messing with them, I wouldn't have gotten the night sight version.

What is disappointing is people have called and Sig sent the #8, yet they want me to send it in and potentially be charged $100-130.

Unfortunately, when dealing with any companies customer service, you get different people with different answers. This happens all the time so I am not surprise to hear. Honestly I would call back and try someone else and see what answer you get.

Generally the reason they want you to send it in, so that any work done, and the pistol will still be covered under warranty.

I do understand the frustration in dealing with the sight issue, and this is nothing new with Sig. Years ago when I was carrying Sigs the first time, years ago sight regulation was a big pain in the arse also. I ran standard trijicons, and had to change sight numbers then as well.

For the performance the 320 is capable of, I'll deal with a little sight swapping....

I found the trigger on my P320c pinched my finger, so changed to a flat Apex, all is good
now.

Yesterday I put the first 100 rounds through my new P320c and initially had 2/3 shots on target but the rest low left by one or two inches shooting from seven yards. I was concentrating on how the pistol cycled, recoiled, etc not trigger control. When I changed my focus to trigger control, low left went away.

Another idea I use for trigger training is to add a rail mounted laser and dry fire the pistol. Put the laser dot on a stationary object, ignore the sights, and dry fire. It is very easy to spot movements during the trigger pull. My $ .02 worth.
