In the context a friend was describing it to me, Springfield's XD series, the .40 falls back to sight picture more quickly than their .45. Likewise he found the natral timing of such was definately given toward a fast double-tap with the .40.
by the math yes, in real life, hard to say. it requires much practice to be good.
Yeah, the 1911 mags are a pretty easy mod actually, as if the engineers that designed the poly frame planned it. I sent a PM to another member a while back bout it, can fwd to ya...Whoa.. Hold the bus for a minute, 1911 mag in HP?? Similar thoughts have crossed my mind, being that I have feed problems with factory mags, but how did you do it?? :brow: I have a JH9 with the old style heel catch, would that work for my gun?
