I love the function of the
Hornady Critical Duty which is 135 grains. I have seen many ammo's fired thru gelatin blocks and the Hornaday is my recommendation for non + P ammo. I agree with those who say to not fire +P too often thru the pistol, that being said, WTSHTF, +P may give you a tad bit more knock down power. I like the
Winchester PDX1 Defender ammo as well as does the FBI.The PDX1 is a P+ round. For a medium to large pistol such as the S&W SD9VE, this is another great self defense load. So I would try either the
Hornady Critical Duty or the
Winchester PDX1 Defender. Remember the Winchester is both non-P+ and +P, so only use for self defense, not too much at the range, get the P+ for Self Defense. It weighs in at 124 grains . Remington makes an Ultimate Defense, but I have not seen too many great reviews on this ammo. I am just going by others who test with gelatin blocks, and have thankfully not had to use any in self-defense!
Alien gear makes a nice pistol holder for the SD9VE which can be concealed carried in a few places for those not 140 pounds. I am 215# and love their ability to have a nice retention, but great ability to draw very quickly. It also seems safe for pistols w/o a safety such as the S&W. Have fun, be safe!
