Yes. The .357 Sig is essentially a necked down .40 S&W (slightly longer case). The Sig round is basically a supercharged 9mm. Texas DPS seems to be happy with it. With the Gold Dot 125 gr bullet it will shoot through automotive parts like doors and "A" pillars and carry enough energy to the target to disable it.
It does tend to over penetrate unprotected targets.
In life, strive to take the high road....It offers a better field of fire.
