Description
The Buck Mark has been a staple in the rimfire pistol world for decades, and the Plus UDX version shows exactly why. Browning starts with a solid billet of aircraft-grade 7075 aluminum alloy and CNC machines it down to a tight, consistent frame. The result is a pistol that feels substantial in the hand without being heavy, and one that holds up round after round without losing its edge.
The UDX in the name stands for Ultragrip Deluxe, and the brown walnut laminate grip panels on this model live up to that. They feature laser-stippled texturing and subtle finger grooves that index your hand in the same spot every time you pick the gun up. The narrow profile of the grip works well across a range of hand sizes, and the ambidextrous design means lefties aren't left out. The frame itself is also machined with matching finger grooves where the grip meets the receiver, so everything lines up seamlessly.
On the sighting side, Browning didn't cut corners. The TruGlo fiber optic front sight pulls in light and gives you a bright, easy-to-pick-up aiming point, while the Pro-Target adjustable rear sight lets you dial in your preferred zero. The 5.5" slabside barrel with polished flats not only looks sharp but gives you a full 8-inch sight radius, which translates to more consistent shot placement at the range. The gold-plated trigger is a nice touch and the single-action break is clean and predictable. The barrel is also hand-reamed and target crowned from the factory, which matters for accuracy.
The straight blowback action is simple and proven reliable. The slide features serrations, cocking ears at the rear, and built-in recesses for a secure grip when racking. The large manual thumb safety and the mag release positioned right by the trigger guard keep everything intuitive and easy to operate with either hand. It ships in a hard ABS case with one 10-round magazine, a lock, and the owner's manual. If you plan to shoot it a lot, picking up an extra magazine or two is worth doing early.

Frequently Asked Questions
What does UDX stand for on the Buck Mark Plus UDX?
UDX stands for Ultragrip Deluxe. It refers to the wood laminate grip panels Browning uses on this model, which feature laser stippling and subtle finger grooves for a secure, consistent hold. The narrow profile is designed to work comfortably for a wide range of hand sizes, and the grip is fully ambidextrous.
Is the Buck Mark Plus UDX a good pistol for new shooters?
It's a great fit for newer shooters and experienced ones alike. The single-action trigger is clean and predictable, the sights are bright and easy to use, and .22 LR keeps recoil and cost low so you can put in a lot of trigger time without fatigue or breaking the bank. The controls are intuitive and well-placed, which helps build good habits early on.
How many magazines does the Buck Mark Plus UDX come with?
It comes with one 10-round magazine from the factory, along with the hard ABS case, a lock, and the owner's manual. If you plan to shoot regularly, it's worth grabbing an extra magazine or two up front since the case has room for additional mags.
Can you mount an optic on the Buck Mark Plus UDX?
The standard Buck Mark Plus UDX does not include an integrated Picatinny rail. If running a red dot is important to you, Browning offers other Buck Mark variants that include a built-in optics rail. That said, the fiber optic and adjustable rear sight combo on this model is solid for iron-sight shooting.
What kind of .22 LR ammo runs best in the Buck Mark?
Like most semi-auto .22s, the Buck Mark tends to run most reliably with quality ammo at 1,250 fps or higher. Brands like CCI Mini-Mag, Fiocchi, and Remington Golden Bullet are commonly reported to cycle cleanly. Very cheap bulk ammo with waxy or dirty coatings can be finicky in any blowback .22 pistol, so it's worth sticking with decent ammunition, especially when breaking the gun in.
Is the trigger on the Buck Mark Plus UDX good out of the box?
Yes, the single-action trigger on the Buck Mark is one of the things that sets it apart from cheaper rimfire pistols. It's gold-plated, clean-breaking, and predictable right from the factory. Many people who shoot it alongside other .22 pistols in the same price range come away impressed with how much better it feels without needing any aftermarket work.
