I have noticed that I am not alone with the symptom of my sigma shooting low and left. I have read that this has to do with getting used to the unique heavy trigger. I have poured hundreds of rounds through the gun and still get consistent tight groups 3" low and 3" left. I have tried slow squeezing with the tip of my finger, but those rounds just go low and left. If I pull with my second nuckle, which is more comfortable, I line up center but remain low. The sights stink, as they are poorly aligned to begin with. I can visually tell that the front sight is closer to the left than the right. However, this would tend to bring the shots to the right of center, not the lower left. I am contemplating changing the sights out but I just want to make sure I am pulling the trigger the way it was designed to be pulled.
 
Keep the sights aligned on target, pull the trigger straight to the rear, and don't flinch or push the gun. There's no magic to it.
 
For the Sigma trigger I would reccomend a C Clamp - that's about the only way you will pull the trigger straight back without shanking.:D
 
i put a Crimson trace Laser on my Sigma. I practiced constantly with pulling the trigger without moving the gun. it works. All shots in a 3 in circle at 21 feet good enough for me.. use a pencil or a penny on top of the slide till you can continually pull the trigger without them falling off.. its all in the trigger.

This would cause the gun to shoot RIGHT, not left. Moving the front sight causes the impact to move opposite.

Move the REAR sight in the direction you want the bullets to move on the target, once you establish a consistent group.

Pulling with all the fingers instead of just the trigger finger causes the shot to go low. Common problem.
 
As steady press, no starts and stops, say (or think) p--r--e--s--s as you p--r--e--s--s the trigger.
Once you learn the technique, it will speed up, but in the beginning keep it s--l--o--w.

Oh, and its a center hold on the target, not a 6 o'clock hold.

I'd start by practicing with a lot of dry firing. A lot. Some suggest using a dime on the front sight but I can usually tell if my sights are flinching without it. Pick out a target in your house, after you've double checked for an unloaded gun, and practice aiming and pulling the trigger. And pick a small target so it will be easier to tell if you're pulling the front sight off target.
 
Pull straight through in one clean motion, put $1 in dimes on the slide or line up sights on a target and pull the trigger keeping target in sight picture as you pull the trigger. If your right handed tighten up your finger grip to pull towards the right and dont anticipate the recoil.

In all double action revolvers or pistols I have found it works best for me if I align the crease in the first joint of my finger with the right side of the trigger. This allows the tip of my finger to wrap around the left side of the trigger as I pull. I also use a stance that allows me to pull back with my left hand while pushing forward with my left hand. I also keep a slight bend in both elbows. Also try the penny or dime trick mentioned above and watch the position of the sights at trigger break. If after some practice your groups are still low left, tap the rear sight lightly to the right and slightly dress the front sight down.

If you are currently using ilight weight ammo consider changing to a heavier weight slug -- with the same sight arrangement a heavier slug will hit higher on the target.
 
I'll also point out that "hundreds" of rounds is nothing. When I purchased my first revolver it was with the intention of mastering a double action trigger. For me that meant shooting twice a week with 150 rounds shot at each range session. It took me a full 8 weeks before I felt that I was shooting as well as would be possible for me. Do the math and you'll find that I sent about 2400 rounds downrange to master the trigger on my model 67. BTW, in the process I found that I really enjoy shooting revolvers and now own more revolvers than semi auto's.

Point is shooting a handgun well isn't quite as easy as some would think and the only sure way to become good is by expending the time and effort that is required.

low left is common for right handed shooters I did it too. better to do it with a sigma than a nicer gun with better trigger. work it out should do well with other guns.

consult the shooters wheel of misfortune
 
There's quite a bit of good advice here. In academy we were trained to ALWAYS focus on the front sight. As the trigger is being depressed, all of your focus is on the front sight.....allowing everything else to be out of focus. That was years ago and the the technique still works for me today regardless of pistol/trigger type. It produces nice groupings every time.

One trick we use for remedial shooters in the USAF (I'm a CATM instructor these days in the reserves) is to put a #2 pencil in the barrel, eraser end near the firing pin. Now put a piece of paper on the wall with a small dot on it for a target. Now you are trying to keep the pencil in the barrel just an inch or so away from the paper on the wall and pull the trigger. The pencil flies forward from the firing pin strike and makes a small mark on the paper. Do this 5 times or so to make a group and you get a good idea what your trigger control is doing. Keep in mind there is going to be that offset from the top of the sights to the center of the bore to take into account but the object here is a small tight group in line with the bore with every shot. Might help, might not but it's another tool for the marksmanship tool box. :)
 
I've had 2 Sigmas. One I carried over 4 years and put about 3000 rounds thru it. I found the best trigger pull is PULL, not SQUEEEEZZZZEEE. It worked out real good for me. Think about it, Sigma's are self defense weapons. In a self defense situation everybody shooting everything from a Colt 1911 to a Bryco Jennings will be PULLING. Train the way you'll be shooting. If you wanted a tack driver you bought the wrong gun. I have switched to Glocks. A G26 9mm for my wife and a G30 .45ACP for me. We have had them about 6-7 months and with 2 trips to S&W and countless hours of my own trigger work on the Sigma's, the Glock triggers are many times better right out the box. For a reliable very reasonable self defense weapon you can't beat a Sigma or probably now the SD or the new VE/SD models.
 
Save the ammo money and sell it and buy something else. Don't spend time hammering square pegs into round holes.
