You look at all the extra metal in those pics and you see the problem with so many handguns. Smith, Colt, Ruger, whatever, they all seem bent on making heavier guns than needed, at least in revolvers. You can get little teeny plastic and steel autos that are super light, but even 22's seem to be super heavy these days. It's all for aesthetics, which equals sales, but theres something to be said for a light, easy to carry gun, especially in the non-magnum cals. Times change...
It's a lot cheaper to not mill off the "underlug" or cut an ejector rod housing. Everyone else caught on. Charter didn't bother with the ejector rod housing (not needed, in my opinion) and Rossi shut down the mill before finishing those barrels. I'm not complaining about THEM, because the customer didn't pay for all that extra work that never got done. Big names continuing to raise prices, yet taking more shortcuts the "cheap gun" have long been criticized for, I look at differently.
Quick mini-rant: OH! And then there's the new wave of doing extra work/machining for no other reason than to make something LOOK different/cool. I don't get that, but it seems to make some people happy.
There's a balance for each person to determine for himself, every gun is not for every shooter, nor is every gun for every situation. I think Charter hit the optimum weight/power combination for the largest number of people, within a reasonable band of uses - mostly concealed carry, but they have offered 4" and 6" guns which make excellent field guns, if not the most fun to shoot 500 rounds through one gun at the range in a session. I don't shoot like that, so it works for me. Five rounds, fifty rounds, sometimes a hundred and I'm happy.
I also just get a kick out of the extra challenge in trying to shoot well with guns which are not easy to shoot well. You never get that good, so you never get bored and you HAVE to shoot them pretty regularly, even if a few rounds. That suits my style, but probably not everyone's.
In the examples I've owned of
@Glaciers ' pictured guns, they were ALL capable of very good accuracy. It's always been on ME to fully exploit their capability.
