Not complaining, just sayin'! Always trying to get better. I just picked up a 22lr conversion for the P226 that has adjustable sights, that should help the situation!

OP you might also want to include mention that shooters sometimes shoot low and left (RH shooters) when they are anticipating the recoil or flinching. Your post is more about the sight picture, but I think this situation will be relevant to people who open the thread for help.

At typical combat pistol shooting distances, gravity has little time to make a measurable difference in POA vs POI (point of aim/impact). Yet bullet weight and speed obviously do. In the same gun, with the same slide and sights (say a P229 with 40 and 357 barrel) the lighter and faster 357 Sig bullet will shoot lower.

The reason for this is that upon ignition two things happen at the same time. The bullet heads down the barrel and the slide starts moving to the rear as the breach end of the barrel starts to cam downward. This camming down of the barrel rear serves to delay unlock, so chamber pressure has a chance to drop before spent case extraction. It has the same effect as would raising the muzzle end of the barrel. Since the slower bullet, stays in the barrel longer, this barrel tilt has more of an effect on its point of impact than it would on a faster bullet, as the barrel breach is still camming down at bullet exit.

This phenomenon is the reason SIG uses different sights as standard on the 9mm and 357 guns vs the slower 40.

I actually sort of allude to that in the trigger pull section, but it isn't well defined. I added a chart and an additonal line or two to clarify. To be clear, I am not just trying to address sight picture. The post is an attempt to list the many things that may contribute to the "shooting low" issues that many newer shooters seem to have. My particular problem was dual (as I think it is with most folks who are new to shooting AND to Sig), I had the wrong sight picture and was yanking down.

Does your Sig shoot low?
.

All the time - when I aim low.

I know, you've all been waiting for it...

My friend has a lot of golf balls hanging on string at his range. Combat hold makes hitting a golf ball pretty tough, much like trying to hit the smaller steel discs.

I don't shoot at golf balls on a string. I do at them on the ground and I can hit them a lot with my 320 compact and 938. Don't do this all the time only when someone leaves them at the range. Boy they can really fly when hit. They will sometimes go over the bunker and into the woods behind it.
320 at 15 yards or so. The 938 more then 10 yards.
I use the combat hold. Seems to be right on at these distances.

I had a new P series pistol shoot consistently 4 to 6 inches low across several shooters and loads, called Sig CS and learned the numbering system for their sights, sent the slide to Sig and had CS replace the #6 rear sight for a #8, problem solved, cost of the new sight included labor, I found Sig CS very helpful and informative

For me, I shoot mostly 1911 pistols with adjustable sights and using the lollipop sight picture. shot this way for the first 30 years of shooting. When I got my first Sig, I may have cursed Sig up and down about shooting low and I was frustrated. I thought it stupid you had to cover the target, I mean, how could I hit what I couldn't see. After being educated on the Combat sight picture, it makes sense as to why it is used. But,that said, at 25 yards my P220ST 45 shoots dead on and my P320c 45 shoots 1" lower and both have #6 and #8 sights.

Unfortunately with Sig suppressor sights there is only one size and they are 6/8
If it's off Trijicon is the only option for 8/8 sights.

I bought a new p226 nice gun but using the combat sight hold it shoots low i know it might be me but that is the way i shoot I don’t understand why sig quit selling the #9and 10 height sights. Seems like it would be good to be able tune the sights for the way a person shoots.I have seen this complaint in numerous forums about guns shooting low i just don’t understand why they quit selling them. I don’t want to put aftermarket sights on my gun when all i need is a #9 or 10 rear sight. If anyone knows a logical reason why they quit selling these sight please let me know

Logical? No, no good reason.

An XD rear sight fits the Sig dovetail and in my experience usually provides the right height difference to hit where you want to hit.

New Member here but not to Sigs. I have 3 pistols and a rifle. All this talk on sight picture raises a question which has come up around the campfire a few times.
In a defensive situation, (less than 7 yds), how important do you feel the rear sight is?
Do you train at this distance? Point shooting or sights?

Both point shooting and sights, although at less than 21 feet, point shooting may, if the target is fully visible, be the only real option due to time considerations.

Maybe a dumb question - has this always been the case? I have a late 90s p239 with contrast sites that seems to shoot with a "target" style hold

My P229 shoots 2 inches high at 10 yards... Had to buy the Meprolight Adjustable night sights. Problem solved.

(I will preface this post by admitting I can be an idiot from time to time)

I spent the day at the range with my 3 P239s today - I realized awhile back that two of them always shot low - well of course they shot where I aimed them... but for some reason with the same ammo and the same shooter (me) at the same distance. One was perfect, well close enough - slightly low and to the right 1" or so... at 7 yards (21'). The others were at least 4" low at the same distance.

I could not remember which ones shot low, so went thru 200 rounds, wrote the serial numbers on each target so I knew which gun went with each target. And rotated thru the group twice, I mixed them up as to not get used to shooting one gun more than the other.

One is a SAS Gen 2 - One is a new one I bought a few years back and rarely ever shot, and one I picked up at a pawn shop used. Of course the one from the pawn shop was the one that I could shoot the best.

In the end - the two I had bought new, that I consistently shot low with had #8 rear, #6 Front.

The pawn shop gun had #8 rear, #8 Front. Not sure if it came that way of if the previous owner swapped them.

I just ordered three SIG SAUER Tritium Fiber Optic Front #8... I am hoping they all aim the same after I am finished.

I also have a P229 - it is a tack driver - but that has an adjustable rear sight that I have adjusted to its max. And a P938, which is perfect as well...

So not sure why the two P239s ar setup that way.

Ooh, and one of the reasons I am an idiot in this case - After I placed the order, I went looking for my sight tool. I found it, and in the box with my sight tool was a new set of #8 and #8 night sights, still in the bag. I must have figured this out years ago, and forgot. :)
