Yes, it's a good gun.
Only two things to need to be cautious about.
1) The ejector rod can come unscrewed, as can some of the frame screws behind the cylinder area. Blue locktite is your friend.
2) These guns are a "tight lockup" design, which means the cylinder is designed to be held rigidly in the rotational direction, moments before firing. This helps with accuracy, and is wonderful when it's running right. When it's NOT running right, the cylinder is held rigidly in a mis-aligned state between the barrel and firing cylinder bore, which means lead shaving plus the gun is trying to really tear itself apart. So you need to do the "alignment check in full lockup" section of the "Revolver Checkout" thoroughly, run milder practice ammo instead of balls-out +P stuff and continue checking the alignment every time you clean it or every 200 rounds or so max. Keep it in good shape though and it will serve very well.
This "tight lockup" process is much like a Colt, except that the Charter locks the cylinder at both the front and rear like a recent-production Ruger DA. There's a few areas of "Ruger similarity" to the design, although it's really more of a similarity to the Colt SAA that made it into both the Ruger and Charter DAs: the action parts "fork up into the frame" without need of side-plates.
The Charter design was always superb. Quality control suffered in the mid-80s and a few other times but you have one from the peak years.
