OP
When it comes to revolvers, I'm all about S&W,
AR's, not so much.
But the charging handle question, did not have to upgrade
on a couple of my Colt's. Feature I wanted 'out of the box'
Knew it was going to be scoped, prior to purchase.
Clearance issue of accessibility and speed with the scope that
I had predetermined was going to be mounted.
I would much rather have plan, and pay up front for what
I want it to be, than throw parts off a new gun in a box and
buy upgraded to replace what I paid for.
