How do you familiarize yourself with a new SxS?

[Big Bad]

I actually prefer to do this before I purchase the gun, It's saved me from wasting time, money and energy on a gun that doesn't fit me dozens of times!

I've had gun salesmen stare at me as if I'd done a headstand right in the store, LOL.

Anyway, everything I've posted here has been about gun fit, adjusting to it, and most of all about developing muscle memory. As a wise man quite recently said, "Train hard, hunt easy."
