Morning all. Over the past two weeks or so I've been becoming familiar with my P320C (9MM). After shooting from various distances (5-20 yards) I consistently see approx 2" low and 2" right no matter what the distance and whether I shoot from a rest or hand. The gun came with #8 rear and #6 front sights (Siglite).

Looking at the Sig chart, I read that the rear sight changes poi 6" per # change while the front sight change per # is 1" at 25 yards.

So should I leave the rear sight at #8 and go to #9 front?

POA was center dot in this pict. 1" lined target. If I remember correctly this target was shot from 15 yards. Orientation of pict is rotated (have to figure out how to adjust that).
The front sight is visually 'off' a little to the left (.6mm). Not sure why it came from the factory like that but have to assume that's causing some of the center shot issue. :eek:

If you are always low and right at any distance, that points more to you and not the gun. If there was something wrong with the gun the numbers would change as your distance moves.

Have you tried shooting off rest? I always shoot a new pistol off a rest for the first mag or two. It helps me remove anything I'm doing.

Also .. have you called Sig? If there is an issue, Sig will fix it at no charge.

My 320 with 6\8 combo is spot on. Granted it took about 4-6 range trips to really get everything dialed in and I'm still improving. Even changing barrels has causes no issue.

Are you left handed by any chance? Almost every post I see about problem with sights has (right handed) people shooting low and left. But the common theme is LOW regardless. I'm going to be bringing mine soon to the range and shooting from rest to see if it does in fact shoot low due to the #6 front sight. If so, I'm replacing with #8. If it does not, I'll learn how to shoot properly.

I shoot great groups a bit low and left with every Sig I own. It's not the pistol in my case but the guy that needs to learn muzzle and trigger control while shooting. I have a flinch that needs some fine tuning.

Heres what Sig told me: The standard factory setup for a P320sc is #8 Front, #6 Rear. I haven't seen anyone even mention that setup on here. My gun came from factory with what Sig said, #8F/#6R.

Just went to range today, shot approx 200 rds at 7 yds. All were low left. The low is probably my sight picture, I am having a heck of a time adjusting to the Sig combat sight picture.

I found that if my POA is right of target, the POI is about dead on.

I did chat with Sig and they have sent (due to arrive today) me a replacement #9 front sight, they said this would fix the low hits. We'll see.

Are they charging you for the sight? I would like to get a #8 front for my compact, but can't justify spending the money right now. I've only had the gun for a couple months.

No, and they are sending a night sight in lieu of a contrast sight.

I simply emailed them and shared my concern of POA not being the POI. Provided them with the sight setup I received when I purchased the piece, serial number etc. Gave them a detailed explanation of what kind of issue I was having.

Next day I had a reply, next thing I knew I received a tracking number for the sight they shipped.

Can't ask for better support than that.

What email do you use for customer support I can't find one on their website.

The first is what I used, Joshua is the tech that replied.
Tawcat - I'm glad you relied. What I've read on this forum is that the compact comes with 8 rear and 6 front (that is what is on mine).
Pretty sure the underline beneath the 6 denotes a 6 and not a 9. :huh:

I'm positive that my front sight is off horizontally to the left which explains the patterns always being to the right of hold.
As I said before, I'm not concerned about that other than I've never had a gun with a front sight not centered on the slide before.

As for those who questioned before, I have the same results off hand and from a rest and I've shot a lot of targets - first from a rest and then off hand. And then I move back 5 yards and repeat. I'll be calling or emailing sig as soon as I have a chance. Sounds like that's the way to resolve my issue with this.

I think it's interesting that your unit came with a different sight set up than mine. I'll be asking that question of Sig. I'm sure there's a good reason :)rolleyes:)

Ya Sig sent me two @8 replacement front sights because I have two P320. One fire control unit and two barrel lengths. I brought them to the gunsmith today.

I thought I had a similar issue with my 320C 9mm as the OP. I got out to the farm and was shooting at an estimated 50 yards to as close as 15 yards. From 50 I was using a makeshift rest and from 15 off hand. All my shooting was at medium speed and everything was hitting 6"-10" low. I was not happy.

When I got back home the next day I got to thinking, before I start blaming the gun I should double check by taking my time and being slow and deliberate. I set up a table with a decent rest and then put an old spray paint can on top of a cardboard box (to show low hits). I estimated the distance at 40'(measured 37'), placed the sights so I only could see the top half of the can and slowly squeeze. The shot hit the can dead center. Second shot I aimed for the center of the cap then punched a hole right in the middle of the cap.

Turns out that there is nothing wrong with the sights. The only other difference was that I was shooting Tula at the farm and Blazer at the house. I have a #6 front and #8 rear SigLites. Just food for thought.
