239 in .357 Sig

I've heard some complaints about the 239 concerning recoil. I like the .357 Sig caliber concept .40 necked down to 9mm. 125 grains at 1425 feet per second. Just like my 4 inch barrel on my Smith 686+

This caliber is serious business in the Sig 239. The advantage of switching barrels to use the cheaper .40S&W ammo makes sense to me. There are buffers on the market as well as recoil reducers for the Sig 239. The HARTTS reducer adds weight, like a tungsten guiderod in a 1911. It contains liquid mercury and steel ball bearings inside a steel guiderod. The trick is to add the HARTTS modification as well as a heavier recoil spring. Brownell's part # 397-100-239... the spring can be bought from Wolff.

Liquid mercury and ballbearings? Wouldn't it be simpler and cheaper to fill it with lead? I do not think that a drop of mercury sloshing around in the rod would significantly affect the recoil.

[Jesse]

It apparently does significantly reduce recoil and is more reliable than any buffer system in such a small pistol. I agree that a lead filled or tungsten guiderod would do just as well,(and probably be a lot cheaper), but the HARTTS system is the only one I've been able to find to this point.

I think lead will float in mercury...for whatever thats worth

I fired a Sig 239 in .357 Sig this weekend. I shot Winchester white box 125gr. JHP. INSANELY ACCURATE! Recoil was not bad at all, to me it was like shooting the 9mm version of the Sig 239 with +p ammo. The Sig 239 is as fine a carry pistol that one can buy! No need for HARTTS reducers or any accessories, this pistol is ready to go right out of the box.
