They are good guns, attractive and comfortable in the hand. Many compare the grip feel to that of a 1911.
My pistol is a Buck Mark Plus with the wooden grips and fiber-optic front sight. It has about 2500 rounds through it. An accurate shooter with good adjustable sights and a nice crisp trigger out of the box.
I occasionally have a hitch chambering the first round -- the bullet tip hangs up on the feed ramp, the slide stops halfway closed and you have to give it a tap with the palm to coax the round into the chamber, closing the slide. However, I can avoid this glitch by leaving the slide open while I change mags and using the slide release button to close the slide and chamber the first round.
Some find that the two lock washers in the sight base (which you must remove to field strip the pistol) tend to come loose with extended shooting. They recommend putting Loc-Tite on the threads. My pistol has never had this problem.
I have heard some reports that subsonic target ammo will sometimes fail to fully cycle the Buck Mark. I shoot mostly regular CCI Mini-Mag 36 gr hollowpoints so I have never had that problem either. I did recently run a box of Eley Club (expensive, relatively soft-shooting target ammo from the U.K.) through the Buck Mark. This yielded some really nice groups. The Eley ammo never hitched up the pistol, but it did fail to lock back the slide at the end of each mag. I don't regard that as a serious problem in a .22.
If I get a second .22 pistol (which is quite probable) it will either be a S&W 41 or another Buck Mark.
