Grew up shooting, BUT...
The weapons were all .22's revolvers and rifles, later Centerfire rifles and the occasional scattergun and later still, centerfire revolvers.
But my first exposure to the .45ACP wasn't till the USNavy in it's wisdom, made me into a Hospital Corpsman and therefore a noncombatent, took away my dungarees, stuffed me into marine fatigues, and issued me a sidearm!
= A 1911! I _Hated_
that thing! Yes, I could shoot it, but man, I wanted a _Rifle_!
If the US Navy wanted me to go hiking with a platoon of 'Riflemen'
I wanted a rifle too! The bad guys knew that anyone packing a sidearm was a more important target that the average groundpounder, I wanted to blend in (& shoot back).
I've read a lot of posts concerning the 'Church of the 1911'...good pistols, but in the real world, they could get you killed!
In retrospect, I never fired a shot in anger, I was far too busy.
I kinda like the .45ACP now that I'm old and mean, but my weapon of choice in this loading isn't a 1911, they are a Sig
and an FEG.
