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...
