When dealing with a compact auto-loader in .45acp, is it of real concern that there is a loss of velocity due to the shorter barrel? Enough that it might be better to get the same firearm, but in 9mm which has a higher velocity?
I've read on forums that a .45acp through say, a 3 or 3.25 inch barrel, has lost enough velocity that you cannot expect HP ammunition to reliably expand. Not sure if this is BS - or something to seriously consider.
I'm considering purchasing a pistol made in both 9mm, and .45acp. Same dimensions. In 9mm, the capacity does jump up 2 rounds. The difference in capacity is not significant enough to me, in that it would sway my decision one way, or the other.
So I'm left with this internet rumor regarding .45acp in a shorter barrel losing too much velocity. So I'm wondering if the 9mm, which has a higher velocity, may be a better choice in a shorter barrel.
Please, no 9mm vs 45acp wars. :banghead:
I have confidence in both rounds.
My questions specifically relate to how they may, or may not be hampered ballistically due to a shorter barrel.
Thanks much.
