Shooting low?

Happy to see this forum exists.

I am having a serious but curious issue with my sub compact chambered in 9mm. The weapon seems to shoot low regardless of ammo weight/quality/+p. The weapon breaks my line of sight because I have to aim high; while I understand that this weapon is designed for emergencies and close quarters, my Glock 33 (sub compact 357 Sig) and S&W Sigma 9mm appear to be more accurate. Range is between and 10 and 20 yards. Again, this could be the shooter, but its not my first time handling a sub.

The weapon feels great and it took about 100 rounds to get comfortable with the weapon. I had one "normal" jam within 100 rounds; probably because of my grip and quality of the ammo. I am a firm believer in 300 rounds + before I can trust the weapon.

Also, I called Sig and they asked that I return to weapon, free of charge, so they can check it out. Now that's what I call customer service. It's nice to deal with a company that cares about the product and the customer! For all they know, I could be first time shooter...no questions asked, they gave me an RMA and said I can expect a response around 2 to 3 weeks.

Am I crazy shooting low? Am I the only one out there?

I had to return my .40 compact for the same thing. They said the wrong sights were installed, and shipped it back. Seems to have taken care of the problem for the most part, but my 9mm fullsize is now doing the same thing.

If you examine the barrel to slide fit, you'll probably find that the barrel tilts slightly downward, and that the greater the distance from target, the lower the gun seems to shoot. I think it's an aspect of the design, but to find out for sure I did a set of shots on a single target with the same point of aim from different distances, starting at about 2 yards and backing up a few yards per shot until I reached 25 yards. There was a steady decline in the point of impact with each shot at the same point of aim, so clearly the barrel was in fact tilted downward. Still is, in fact, but the sight change corrected for it to a large extent.

Huh

I noticed the the same thing and performed a similiar, but less scientific test. Sine I am far from a gunsmith, I did not mention this concern but I do agree about the tilt. Hopefully Sig will fix it because I like the feel of the weapon. Thanks for the response.

The weapon is shipping to Sig in the morning.

Thanks...

Yes, the first 250 rounds through a 9mm compact showed need to hold up the sights to get the groups to center. It needs a shorter sight. Wonder if SIG would send me a shorter sight, rather than go to all the trouble of shipping it back. A lot depends on which ammo you are using. +P would shoot flatter.

It is a bit ammo sensitive. It likes good ammo, doesn't seem to like WW WinClean with its semiwadcutter profile, and throws the empties straight back, some hitting my hat. All the carry ammo with HP's did just fine.

don't know if it helps or not but the first few times i went to the range i was shooting a little low until i realized i was actually pointing it slightly downward, once i fixed the way i was holding the pistol I've been dead on with every shot.

I got my p250c a couple of months after they came out and had the same issue with it shooting low. I contacted SIG because I thought I had the wrong sights on the gun. They confirmed my sights were correct and suggested trying different ammo. I was using 115gr ammo. I tried 124gr and 147gr and found that the 147gr ammo was right on target.

Lightfighter6 and Tank 44:

I shoot my other SIGs and Glocks perfectly fine. Two guys named Ayoob and Farnam can certify this. They know me a lot better than you do.

But my 9mm compact P250 shoots low. A lot of other guys are reporting this. SIG evidently sent out a bunch with the wrong sights. I will get shorter sights put on. That will fix the problem.

But, anticipation, no.

used 124 grain ammo today. Im satisfied with the result.
Range Officer did help me out try to adjust my trigger to minimize movement while pressing the trigger. Also tried the penny test for 2 weeks now. And I'm pretty satisfied with it.. compared the first time I went to the range where I shoot low and to the left with 6" distance to the target.Blushing

I shot my 250SC for the first time today. With cheap Monarch 115 FMJ it was regulated perfectly (both side to side and up and down). After putting 50 flawless rounds through it I changed to 147 gr Speer GDHP to check them for function. I am thinking abou this as a carry load. Surprisingly the heavier bullet hit in exactly the same place -- I had expected the heavier bullet to hit higher. I was shooting at combat range (5-7 meters). I can only speculate that with the short barrel recoil radius has less influence on POA than with a longer barrel.

I am very happy with this pistol!

I just bought the 9mm Compact and shot it for the first time today. I am a seasoned shooter and am usually dead-on with my many Glocks, Sig p2022 and Sig P230 shooting groups 1"-1.5" at 30'. However, like many here I experienced the same problem shooting about 1"-2" low today with the P250 (depending on the distance.)

So I too feel that it must be related to the sights and/or barrel tilt. My front sight is also a #6. Does anyone know if this is the correct front sight or should it be a different number? Might I also say that my buddy, whom is also a good shooter, tried the pistol and also shot about 2" low.

This is waaaaaaay too common to be just us. I just purchased 2 sig 250c's in 9, one for my son and one for me. BOTH have the identical problem, as all were low by 2-3" at 10yards. The book states to get a different sight, though I am inclined to try different ammo before I call sig, now that I have heard ammo might do it. I can say that at a consistent hold high (front night sight dot halfed by rear, instead of aligning top of sights or dots) I am dead on 100% of the time. A smaller front or larger rear sight would solve this. I have the p250c with nights using Win White Box. Still, at this distance, it shouldn't make that much diff by just ammo.
If at first you dont succeed, a double tap usually does the job.

I don't believe it is ammo related. Were you using a combat or target sight picture? The P250 is designed for a combat picture, which is the reason many people shoot low. That may not be your problem, but just throwing it out there.

Shooting paper body shadow form with hostage. After more research it looks like there are several sizes of sights. Need a larger rear or smaller front sight. Will see what Sig has to say.

There are several different size sights available, but I'm talking about the sight alignment picture, not the type of target. There are multiple types of sight pictures, and the P250 uses a combat sight picture, where the front sight covers the target rather than a picture where the target is "sitting on" the front sight. If you swap out the sight and it turns out that the problem is the sight picture, you will find that the weapon is accurate at one distance, but off at all others.

Check out this post to see what I'm talking about. The P250 uses picture #3.

Oh, darn. I will have to go our and shoot it again, just to be sure. I would agree, #3 is the closest to true. I am used to (shown above) using sight picture #2. I actually dont recall if 3 would work, but again, will be shooting again soon just to see.

Thanks!

My P250C 9mm came with a #6 front sight. It always shot 2 to 4 inches low. I just replaced it with a #8 sight. It is perfectly regulated. Place the front sight on a target and that's where the bullet goes. That would be a #3 target picture. SIG put the wrong sights on this model.

Please don't talk about "anticipation". Go and learn to shoot and get your gun sighted in properly.
