I don't have a wide basis of comparison to other .22 handguns, but I love my Buck Mark Plus and think it was a bargain at $350. (The Plus is the model with a green dot Hi-Viz front sight and nice-feeling wood grips.) I've had it for the better part of a year and have put c. 1000-1100 rounds through it. It looks great (I like the Browning's lines better than the Ruger's) and feels well-made, an impression confirmed by its shooting behavior.
It is the most accurate firearm in my modest collection. Shooting from a bench with open sights, I shoot the Buck Mark more accurately at 50 yards than I can shoot my centerfire
rifle.
Straight out of the box the little Browning had a wonderful trigger. Perhaps because of this advantage, fairly rapid strings of fire are, if anything, tighter than groups produced by pausing and aiming between shots.
There were a couple of stutters in the first 200 rounds (FTF, slide staying open after a shot), then after that, perfect reliability. I have only broken the gun down and cleaned it once.
Passing into the realm of hearsay, I've read of lazy people
going thousands of rounds between cleanings, without trouble. When they finally break the Buck Mark open, astonishing buildups of gunk greet them. But the pistol still shoots.
My Buck Mark is a true class act.
