I ordered a Kahr PM9 and am looking for carry ammo to use in it. I carry Gold Dot +p 124 grain in my K9. Speer makes the Short Barrel for 3.5 inch barrels in particular and so I wonder about that, it supposedly is designed to expand more reliably with the lesser velocity from shorter barrel lengths.
Putting aside the question of whether 1/2 inch of barrel difference necessitates a whole different type of "short barrel" just to expand reliably, what I WOULD like to figure out is if Cor Bon's DPX all copper bullet would be more likely to expand more reliably from a short barrel like the PM9 when compared to any others of the jacketed variety. Short Barrel Gold Dots can't be had anywhere on earth right now anyways so it would be between that and the normal 124+p that I already use.
I ask this partly because in researching DPX for the .32, it is able (according to Cor Bon's specs) to make 1050fps from a 2.5" barrel which I suspect comes specifically because the bullet is copper. (by that I mean something about producing the bullet in the way that they do because of its material and weight.) It would stand to reason I might get much higher velocities from the PM9 because of this then with any other kind.
I know that "you cant go wrong with both" but I would like to know your thoughts on the particular properties mentioned, even if just out of curiosity. No one talks much about DPX except to say that its promising.
