The Earl weighs 8.6 ounces, the single six goes 35, one hell of a difference to me.
Reasons NOT to carry a holstered handgun:
#1 I hate the weight of a holstered handgun rubbing on my hip bones and the heavier it is the more I hate it.
#2 The belt holstered handgun is inaccessible under a long coat.
#3 The belt holstered handgun is a problem if you have to drop trousers in the woods.
#4 You have to keep changing the handgun around as you add or remove layers of clothing.
#5 The holstered handgun sticks out and catches on things like gate posts, truck doors, hay bales etc.
#6 Unless you wear a full flap holster the handgun is subject to lots of dirt and dust, rain and snow.
Actually wear a handgun all day every day and you'll probable think of a few more reasons I've overlooked.
With a half pound revolver you can just drop it into the pocket of whatever you are wearing as an outer garment at the moment and forget it's there.
Yes it is just a longer barreled version of the mini-revolver. So why is that a bad thing? Personally I'd prefer the "mini-Master" with 4" barrel and adjustable sights. The bull barrel increases the weight to a whopping 10.7 ounces.
But again, I'm thinking of plinking, small game and vermin, I'd never consider any .22 for self defense.
