I recently bought a Sig P320 Compact with SIGLITE Night Sights. It currently has a #6 front sight and #8 rear sights. I've taken it to the range a few times now and it seems like the gun is always shooting low. Even today, I took it to the range and had to aim pretty high in order to hit the steel targets. Is this to be expected from my P320 or is it possible that I am doing something wrong? I am a newer shooter and it's definitely possible that my form or sighting could be off, so any tips would be helpful. I have had a couple of other more experienced shooters try shooting the gun and they also were shooting low. As far as my sight picture goes, I've tried aiming with a 6 o'clock sight, a center hold sight and a combat frame hold sight .. I just can't seem to hit the target without aiming well above the target. Any suggestions would be appreciated. Thanks!

Shoot the gun from a rest to exclude the possibility that you have a technical issue with your trigger press. For example, some shooters push the gun forward and down in anticipation of recoil.

If it truly is sighted low, you can fix it by replacing the front sight. Call SIG and see if they will take care of you.

Whenever I encountered the described problem early on in my shooting, I found that it was my anticipation of recoil... not the sights. Try using DBS's solution, or what I did was to load some snap caps (dummy rounds) in my mag randomly. Load the mag without looking at the bullets/snap caps, or have someone else load it for you.

When I was shooting and encountered the snap cap as I squeezed the trigger, I would catch myself dipping the muzzle and then realized it was me trying to anticipate the recoil.

My solution was to firm up the grip, concentrate on trigger squeeze... straight back, and use more pinkie (little finger) pressure from both hands in my grip. The break should come as a surprise... even though you're "looking for it" so to speak.

Hope this helps.

Morning twoface01

Almost every Sig that I own shoots low (for me anyhow) as received. Sig seems to set the gun up for using the sight dots not the top of front sight post.

I usually change out the rear sight for the next higher sight as it is usually easier for me to change the rear sight than the front one.

In the mean time you might try heavier bullets (in 9mm the 147 grain shoot more to POA for me anyhow).

#6/8 sight combo is made for .40. 320s are notorious for coming with all sorts of inconsistent sight heights. If you have a 9mm, id suggest going with #8/8 sights and that will bring up your shots...as the #8 front height is lower which will bring down the rear of the pistol.

All my Sig P320 in 9mm have 8 front and 8 rear and they are spot on with a combat sight picture. If you have a #6 front the sight is too tall and you'll always shoot low.

My P320 40cal has a 6 front and 8 rear and the sight picture is just right for a combat hold.

I despise the combat sight picture. All my other pistols have sights that the bullet impact is at the top of the front sight. When I find the right sights to get my P320s to aim the same way as my other guns I will change them all out.

Congrats on the 320 and welcome from MO.

Many have reported fixing this same issue by replacing the front sight to #8, which is shorter.

Is there an idea or an expected elevation change with #6 vs #8 front sight? x inches difference at 10 yards, or anything like that?

I found with low left on this, dealing with anticipation (weird when I my first pistol was a 40SW 2022), regardless of tip, pad or joint of trigger finger, it still shoots low and slightly left. After over 700 rounds, making sure it is not me, it still shoots low with a #6 front sight.

Best I could do with a rest was a make shift rest on an ammo can with a towel under it and the grip-- at 5 yards, it shot one hole but still slightly low left. Maybe there's still shooter error?

for me is was 2-3 inches at 10-15 yards with 6/8, so went with 8/8....Also, check your sight alignment....mine was off to the left a little...moved to right and I am much more in there...although my groups are a tad larger than I would like....but still in the kill zone

Sure, checkout page 55 in the P320 manual. Link and text below.

10.3 Elevation (Up/Down) Adjustment
There are different height combinations available for the front and rear sights.
The sights are numbered according to their height. You can change elevation by changing either the rear or front sight. It’s easier if you change the rear sight first. There are six rear sight heights available. Each rear sight change will move the impact of the bullet approximately 2” at 25 yards. There are five front sight heights available. Each front sight change will move the impact of the bullet approximately 1” at 25 yards.When changing sights, remember this rule: NUMBERS UP, GROUPS UP; NUMBERS DOWN, GROUPS DOWN. This is true for both front & rear sights.

Same pistol - different factory sight set up. Huh. Anyone know why a gun manufacturer would purposefully do this? Makes no sense to me. (No more #8s in the parts bin at the factory production line perhaps??).

Anyway twoface01, mine with #8s front and rear is dead on at 10 yards with a combat sight picture hold. Good luck with your front sight change. I think that it will be worth it for you.

Perhaps this article will be of help here:

https://www.realgunreviews.com/sig-sauer-sight-heights-sight-numbers/

Please note that both the 9 mm and the .40 320C normally ship from the factory with #8 rears and #6 fronts, and that changing your front sight to a #8 will only raise your POI by a mere 2 inches at 25 yards.

It sounds to me like your POA/POI discrepancy is larger than that, so I'd first exclude problems with the shooter before I began to monkey with the gun.

Thanks, I'll have to look into checking sight alignment too.

Thanks, I remember reading that over 700 rounds ago LOL.

For the record mind is also a 6/8 setup, 9mm COMPACT size, I think 1/2017 manufacture date.

I never made it past 15 yards during target practice since it's not hitting exactly where I want. I'd shoot mainly 3-5-7-10. My groups are decent-- fist-size, up to 7 yards. My concern grew at a range I go to where I couldn't hit the steel plates 6" diameter I'm guessing at 10 yards, but have no problems doing so with my other pistols-- including two Shields.

Everyone raves about the P320 accuracy, I thought of ditching it several times (even wondering if I'm a "40 guy" since I hit with my 40SW 2022) but kept giving it more chances (rounds).

Guess my makeshift rest won't do and I'll need to retest and if anything contact Sig for the #8. I'll try at 10, 15, 25 yards to compare those numbers.

Shield LEFT, P320 RIGHT 5 yards. Tested 5 yards.



Wish it didn't take 700+ rounds to find a sight alignment issue.
