Who else can't shoot .357Sig accurately?

I recently acquired a Sig Pro in .357Sig. My other Sig is a .40, so I bought an extra barrel in .40 for the Sig Pro. I finally got to shoot the Pro today. At 10 yards I couldn't shoot near as well with the .357 round as I could when I swapped over to the .40 barrel. I was extremely disappointed. I couldn't hit the upper half of the target - all 60 rounds were below the center line. Once I popped in the .40 barrel, I was all over the bullseye. Has anyone else had this happen? I would not have thought a different round would have thrown my shooting off that bad...:confused:

I wasn't particularly accurate with the .357 Sig in a Pro when I first tried the round. I'm not particularly accurate with the Pro in 9mm either, one of the reasons I sold mine. The gun was just too small (I find the 226 to be a nice midsized handgun, for scaling perspective :) ).

My 226 in .357 is scary accurate. I shoot it as well as the 9mm, and it's got easily double the effective range.

Where it fails is rapid followup shots. Recoil is just too sharp to get them off anywhere near as fast and accurately as I can with the 9mm in the same platform.

It's relegated to range fun and training for me now; what it excels at is the equivalent of training with a heavier bat in the same size. After a couple magazines of .357 the 9mm is an absolute joy.

Sight regulation problem with the gun? If you are using a consistent aiming point and are shooting tight but low groups, light and fast bullets do tend to shoot lower than slow heavy ones. If your shots are more spread out over the target, either there is an accuracy problem with that load or barrel or you have a technique issue that needs to be ironed out.

I am no expert, but best guess. iirc SIGs use different front sights for .357 and .40? Could be why your shots were low?

Yeah, it's rare to get a multi-caliber setup where the sights are both regulated even in the same ballpark.

.357 has very little practical dropoff as well due to velocity and weight.

I am not sure what was going on. Even though it was seated correctly, I did notice that the recoil guide rod was leaning slightly left when the slide was pushed back over the .357 barrel.

As for the sights...This gun is made to interchange barrels, I've never read anything about adjusting sights for a different load.

I was not aware that a faster bullet would shoot lower. That would make sense in this case.

Regardless, I'm still not sure I want to shoot the .357Sig...ammo is almost twice the cost of .40. I don't see myself shooting through barriers anytime soon, so I may just stick with the .40.

ditto on 357SIG shooting lower. I switch to a 40 barrel on my 226 and it shoots 2" high @ 10 yards (180gr vs 125gr). I couldn't shoot 357SIG as well as 45 or 9 and thought it was the caliber. Turns out I just needed a little practice. I was anticipating the shots too much (maybe partly the recoil and partly the cost of ammo making me overthink to make every shot count). Getting the 40 barrel helped - I shot 100 rounds, switched back to 357, and shot without thinking about it - 357 group was smaller than 40.

I don't have the info where I can lay my hands on it right away, but the parts numbers for the sights of SIGs in .40 and .357 are different. A SIG with conversion barrels and with fixed sights will only have proper vertical point-of-impact, at a given distance, with one barrel.

I'm still not clear. Are you saying:

1) the point of aim changed when you switched to 357 SIG - in this case, you would still be shooting tight groups, but the groups are centered low on the target instead of on the x ring

2) the group size opened up AND tended to center low on the target

If 1), then it's the sights.

If 2), it's something else - possibly on the shooter side. Shooting low and more random groups is often a symptom of the shooter anticipating the recoil and/or flinching. 357 SIG, having sharp recoil and (depending on load) a lot of muzzle flash, is a caliber that might encourage development of a flinch.

My experience with shooting 357 SIG vs. .40 SW in the same SIG pistol is that when I am doing my job, I shoot 357 SIG more accurately. However I do have to be conscious of the tendency to anticipate the recoil and work to avoid this. If I don't do my job, my groups do tend to open up and get low with 357 SIG.

Best way to tell if its you or the gun...ball and dummy.

I recently acquired a Sig Pro in .357Sig. My other Sig is a .40, so I bought an extra barrel in .40 for the Sig Pro.
So the gun was originally manufactured as a .357 SIG. In that case the sights should have been regulated for that load, and if anything the .40 would shoot higher.

This is becoming even more puzzling.

When we went from the 9mm to the .357sig. our department over all scores went down. Last time i talked to our range master he told me even now the scores have not risen to the point they were with the 9mm and we been shooting them for around 9 years now. The .357 sig round is a very good round just it does recoil much more then the 9mm follow up shots are harder if one does not shoot it a lot and that where the problem is lot of our LEO's are not big gun people and don't go shoot on thier own thus the lower scores i feel.

Be safe

Unfortunately department heads (almost never gun people) sometimes get talked into it as a "magic round". Its a 9mm major, thats it.
