He was complimenting you on your conversational skills using moments of recollection to interpret the old adage, "if it doesn't start with a 4 . . ."Sorry, my friend. I was trying to do that or talk down about what you like. Just throwing some thoughts out there about what works for me.
Let's face it, nines are convenient, smaller, and easier to carry which encourages the spray-n-pray in my opinion but anemic compared to a 45, 40, or the 10mm. My big hands crave a stacked 45. I can still palm a basketball.
I wish they made a 45 Magnum commercially.
A 45 ACP about 1/8 longer like a 38 v 357 Magnum, or 44 Special v 44 Magnum . Hoooo Ah!
