View Full Version : SIG 226 in .40 or .357

I'm looking at a Sig 226 as my next pistol. I've already got 9's, 45's, and 22's, but I like options. I know that with a 226 chambered in .40 I can change out the barrel for one in .357 and be done, or vice versa. I was wondering if there is any difference in .40 with a .357 barrel change or .357 with a .40 barrel change. From what I understand, everything else on and in the pistol is the same, except maybe a recoil spring change, but that seems negligible on a Sig. Is it anything like .223 and 5.56?
If anyone has experience with this (on any platform), or has info that could educate me on the issue, I'd appreciate it.

Yup it's the same. I've owned mostly .40S&W and just picked up a .357SIG, the recoil is almost exactly the same.

Buy the .40 and get a .357 barrel and spring. Both rounds uses the same mags.

Likely the largest difference will be the POI change between the calibers

a Sig p226 in .357SIG would be kinda cool.

I have a 226 in .40, and have shot a 357. Not a heck of a lot of difference IMO.

I have a 226st to soak up recoil. I keep the .40 barrel in but I did buy a .357 sig barrel. It's much louder.

+1 for .40

My off duty is a P239 in the .357Sig...Fun, hot lil round!

^^^ This ^^^

I've had a P226 in .40 for close to ten years. No desire to even buy an extra barrel for .357 Sig.

If I remember right someone saying that you can use 357sig rounds in the 40cal mags but you can't use 40cals in the 357sig mags.

The mags are interchangeable...the 357SIG is just a necked down .40 S&W

Just like the .357 magnum. You don't know loud until you've shot a .357 without ear plugs.:)

This is correct. SIG P226's (and P229's) when they ship from the factory as 357SIG use a different front sight than P226's (and P229's) that ship as .40S&W. One is a #8 front sight, and the other a #6, if I am remembering correctly, and I always forget which caliber uses which.

However, and FWIW, the minor difference in point of impact is negligible for the purposes of a defensive weapon or range fun. I often shoot both P229 and P226 at the range and will swap barrels there, and the POI difference really doesn't matter much.

There is no change needed in the recoil spring, they are the same. Magazines are the same as well.

I really like the idea of having both barrels; I recently also got a 357SIG barrel for my HK P2000 SK. If you are at all leaning toward being able to use both calibers, I'd check to see which I could get the extra barrel faster for, order it, and then get the P226 in the other chambering.

Example, as of this post, Top Gun Supply has .40S&W P226 barrels in stock, but the 357SIG barrel is not. Sometimes SIG barrels are a long wait, and 357 barrels sometimes a longer wait.

I'd just stick with .40. There's no real advantage to .357sig under any circumstances. .40 is only going to get cheaper and more widely available, particularly if the military adopts it with a new pistol, as it seems likely to do.

.357sig not so much.

Minor difference is of course relative to the accuracy expectations of the shooter. The difference between the point of impact of the #8 and the #6 front sights is 2"

Only major difference between teh 40 and 357Sig is the PRICE on 357Sig ammo.

.357 Sig offers almost no advantage as far as terminal performance goes over 9mm +P loads. What you do get is an increase in blast, and a decrease imagazine capacity (in free states). .40 S&W has a real advantage no matter how small over 9mm, and .357 Sig in both expanded diameter, and better penetration after passing through intermediate barriers like windshields.

I have both. I would get a 40 and buy the 357 barrel only for one reason. The resale value of the 40 is probably slightly higher for at least two reasons. One, 40 ammo is cheaper than 357sig. Two, some think that the 357 round puts more stress on the gun and would thus consider it in respect to the overall value. It is fairly easy to find 357sig barrels on Sigforum and Glocktalk. All that being said, the 357 round is great to shoot.

So you're saying that POI for 357SIG vs .40S&W is a 2" difference? At a typical defensive pistol range of 25" or less? That surprises me.

No, I'm saying that the difference of POI between a #6 front sight and a #8 front sight is two inches...the front sights are numbered to change the point of impact one inch, in the direction the number changes, for each increment when measured at 25 yards. (the rear sight blade numbers change the point of impact two inches)

If I was involved in a confrontation at a typical defensive range of 25", I'd be going with a blade or open hand technique ;) (25"= 25 inches = 2 feet + 1 inch = contact distance)

I checked, because in practical terms I personally don't experience much real difference if I take either my P229 or P226 to the range and swap barrels out between .40S&W and 357SIG, so color me skeptical, or color me blind.:)

Either way, you are correct; 1" at 25 yards per number, so 2" at 25 yards between #6 and #8.

FWIW, at a maybe realistic difference in a real world defensive shooting, say at 15 feet (5 Yards) that works out to 4 tenths of an inch, the diameter of a .40 caliber bullet. However thanks to your clarifying of the differences, I do feel a little better that the one I have chosen to carry (P229 in 357) came from the factory as a 357 and therefore has the right sights.
