Any questions you may have call Underwood at-

P.S. Its possible that this ammo traveling at 1500fps would hit the target extremely hard would also having a shock effect.
South Bend, Indianna have used Corbons 135 gr jhp @ 1325fps with
dramatic effects. Now lets pump up that muzzle velocity
by an extra 200fps and you got one haymaker of a punch.

maybe so but that 135 in a 40 cal is has a sectional density of like 1.21. it is going to slow down like a parachute, once it hits the fat layers and muscle the bullet will likely be sub sonic through the vital organs. esp a larger built BG.

going super sonic through the vital organs like the 357 does seems to be key in the police saying of "lightning bolt effect" I'm sure it would kill as good or better ,but we want the extra shock to STOP the attacker

The 357 sig can launch a bullet with a sectional density of 1.41 at 1500 fps from a 4 inch bbl. with that kind of sectional density the bullet does not slow down much as it penetrates probably going 1200 fps through vital organs.

The 9mm 45 and 40 can NOT do this. I'm sure a skinny bad guy it might, but some of those 260-350 lb attackers have extra layers to go through and the Sig seems to be able to break the sound barrier inside of the BG vitals.
