Unknown quantity from my end. I believe the load you're talking about was developed for a major LE agency, but I'm not sure how much of it was issued or whether it was ever actually used in the field. The agency in question, last I knew, went to 180 grain subsonic instead.
If it turns out to be the same as Federal's low recoil personal defense 135 grain load, I only did one case where that was used. In that instance, the attacker was hit mid-torso and jack-knifed forward, staggered away from his attacker, and jumped in a car which his accomplice drove away. He died in the car. That would fit most folks standards for a "one-shot stop," but it's only one case.
That particular load was considerably lower in velocity than the Cor-Bon 135 grain JHP, which has variously used Sierra and Nosler bullets depending on the production run, and earned an excellent reputation as a man-stopper. If I was going to go with a 135 grain JHP in the .40 S&W, I would definitely want the full power (1300 fps or faster) Cor-Bon, or one of the similar loads from Buffalo Bore or DoubleTap.
Sorry I couldn't be more help,
