Description
Browning has been turning out the Buck Mark since 1985, and the Plus UDX configuration is the one that leans into old-school good looks without giving up a thing on the target range. This version pairs a stainless 5.5 inch slabside barrel with polished flats against a matte black aluminum frame, so you get that two-tone contrast along with the corrosion resistance stainless steel brings to the table. Weighing in around 34 ounces with a 9.5 inch overall length, it has enough heft to settle in your hand without feeling like a brick.
What Makes the Buck Mark Plus UDX Frame Different
Every Buck Mark starts as a solid billet of 7075 aircraft-grade aluminum alloy, CNC machined down to tight tolerances rather than cast or stamped like a lot of budget .22 pistols. The barrel is fixed directly to the frame instead of riding on a tilting lockup, which is a big part of why these guns shoot as flat and consistent as they do shot after shot. Add in a hand-reamed chamber and a recessed target crown at the muzzle, and you have a barrel built for precision rather than just function. The single-action trigger on this model wears Browning's signature gold finish and breaks clean, with barely any creep before the shot goes off.
Sights and Grip on This Buck Mark Plus UDX Pistol
Up front you get a TruGlo/Marble Arms fiber-optic sight that pulls your eye to the target fast, even when the light isn't great. Out back is Browning's Pro-Target white-outline rear sight, adjustable in 16 clicks per revolution for windage and elevation, so dialing in your preferred load takes minutes, not a whole range session. The slide itself is serrated and drilled for a Picatinny rail, meaning a red dot bolts right on if you decide irons aren't your thing anymore. The UDX name stands for Ultra Grip Deluxe, and the black wood laminate panels here are shaped with finger grooves molded right into the frame, giving you a grip angle that points naturally and holds steady through a long session at the bench.
This is a straight blowback .22, so there's no tilting barrel or locked breech to fuss with, just a simple, reliable cycle that handles just about any .22 LR you feed it once it's broken in. The 10 round single-stack magazine loads easily thanks to a thumb-assist button, and the manual thumb safety plus reversible mag release sit right where your hand expects them. Whether it's plinking cans, working through a box of practice ammo, or teaching someone the fundamentals, this Buck Mark checks the boxes for a rimfire pistol built to last generations.

Frequently Asked Questions
What does UDX mean on the Buck Mark Plus UDX?
UDX stands for Ultra Grip Deluxe, which refers to the black wood laminate grip panels on this model. They're textured and shaped with finger grooves built into the frame itself, giving you a more natural point of aim compared to the standard grip options.
Can I mount a red dot on the Buck Mark Plus UDX?
Yes, the slide on this model is drilled and tapped with an integrated Picatinny rail, so a red dot bolts on without any gunsmithing. The factory iron sights are solid enough that plenty of owners stick with them, but the option is there if you want to add optics later.
How many magazines come with the pistol?
It ships with one 10-round magazine, along with a hard case, lock, and owner's manual. Extra factory Browning magazines are widely available if you want to keep more loaded and ready at the range.
What ammo does the Buck Mark Plus UDX run best?
Like most rimfire pistols, it can be a little particular about ammo before it's broken in, but tends to settle into reliable feeding after a couple hundred rounds. Standard-velocity target loads tend to group tightest for slow precision work, while bulk high-velocity ammo like CCI Mini-Mag runs great for casual plinking sessions.
Is this a good pistol for a new shooter?
It's a solid choice thanks to low recoil, a comfortable grip angle, and a trigger that's easy to manage without a lot of practice. The weight of the pistol also helps keep it steady on target, which makes learning the fundamentals less frustrating.
How accurate is the Buck Mark Plus UDX out of the box?
Very accurate for a rimfire pistol in this price range. The fixed barrel design, hand-reamed chamber, and target crown work together to keep the barrel steady, and most owners see sub 2 inch groups at 25 yards with decent ammo off a rest.
