I was raised on the 1911. first big bore gun I bought was a 1911, now I seem to collect them, Im waiting on delivery of my 28th 1911, I can shoot them well, I can hit what I aim at, I am comfortable with them, I think that's the whole thing, are you comfortable with a weapon,. can you hit with it, does it go off every time, I shot IPCS for about 30 years, Im comfortable with what I can do,
I do have several browning hi powers, in 9mm the kids like to shoot them, the grip just dosent seem to fit me as good as the 1911 does,
I you can also think shot placement is more important than bullet size.
