Standard Pressure Short Barrel Low Flash Heavy .38 Special Pistol & Handgun Ammunition
They load them pretty darn hot and use special blends of powder to get the most from the short barrel. I can actually tell the difference in the recoil from a 130 grain target load when I mix them in the gun. Their claim of getting the most from a short barrel seems to be true.
If your gun can handle the +p then go with the Buffalo Bore +p. You will not regret it.

If they made a 40 caliber standard pressure, that's what I would carry in my Glock.
