Sharps; By use of the interchangable drop in factory Sig barrels, the Sig 229,239,and 226( stainless slide version) can be converted allowing the pistol to accept either the .40 S&W or the .357 sig cartridges.Since both cartridges uses the same .40 S&W cartridge cases the chamber remains the same,the only difference is in the size of the bore of the barrel.As far as which is best and for which application;the .40 S&W bullet is is a larger diameter bullet with adequete energy required for defensive purposes but due to the thickness and size of the case,pressures can be limited for increasing the velosity of the .40 S&W bullet.The .357 sig,being a smaller diameter and lighter bullet on the bottle necked .40 case displays energy and velosities commonly found in the 125 gr. .357 magnum cartridge.Delivering the high energy of the .357 sig on an intended target would have alot of shock stress on impact, combined with penetration and bullet expansion from a smaller bullet.The larger .40 S&W bullet that displays muzzle velosities of 1,000 fps with 180 gr.and 400 fps of muzzle energy lacks little in performance .Because both are excellent cartridges for the applications of their intended use,I cannot say one is better than the other, but rather one hand washing the other in choices for the individual user.For velosity,penetration, and energy, my choice is the .357 sig;for close range defensive applications with a lesser felt recoil and larger bullet diameter,my choice would go to the .40 S&W.

Sharps;It takes me awhile to get back in here since they changed their settings.One thing that led me to these two cartridges is the shooting performance and feel of them.I bought into both over four years ago,the .40 displayed a package that I could feel comfortable with besides a .45acp,and the Sig 239 was the pistol that fit what I needed in a smaller pistol with a 180 gr. bullet.When the .357 sig came shortly after, it displayed increditable energy,accuracy,and cycle speed from one shot to the next,a real show stopper.As I have already said,I'm fond of both cartridges for different reasons and for my own uses I prefer to have both without having to make a choice between these two except when I feel the need to do so.

Dubble,
Do you believe that the 357sig is more accurate at longer ranges than the .40? I know the BARK is much more. It would seem that you could reach out a ways with it. What are the Mag interchanges.

Doc;Pleased to have your acquaintance.For me the .357 sig displays superior accuracy over the .40 S&W at 25 yds.I have worked on this using two different 229 Sig Sport pistols,one in the .40 S&W and the other in the .357 sig.Both are mild mannered when compared to cartridges like the .45 ACP.What I get from the .357 sig is Accuracy,distance,and speed.The .357 sig seems to cycle faster but the shorter recoil of the 239 wreaks havoc even with the some of the better defensive ammo in .40 S&W at closer ranges.Like I said,I am fond of both for particular reasons.

The question regarding the magazine interchange;the 229 & 226 uses the same magazine for both cartridges.But the Sig P-239,because it's a vertical single stacker, is different . The .357 sig mag for the 239 is narrowed toward the front up the length of the magazine forming a channel for the bottle necked shape for the .357 sig.The 239 is the only case for using different magazines.
