Well Gman686, happy upcoming 40th!
Since you're going to be 40, why not start your revolver search for something that's your age or older? That way, you'd be getting one without the lock. Older 19s and 10s are both fine well balanced revolvers that come in various barrel lengths.
The 19 is a great revolver. I've seen the 4" are most common. Plus, they shoot .357s and .38s whereas the 10 is only .38
Not that there's anything wrong with a 10 either. Heck, I just picked up my first 10 this week; a 10-4 4", and it's really nice.
Decisions, decisions...tough one.
You did say: "Im open to all and any suggestions."
Hmmm, all suggestions? Why anguish over that choice? You only turn 40 once, so why not get ALL SUGGESTIONS? Reward yourself twice! Yep, get a 19 and a 10, make it a birthday to remember!
