Pros & cons
What works
- Crisp 3.5-pound single-action trigger—1.5 pounds lighter than most Ruger Mark IV models

- Weighs 28 ounces—4 ounces lighter than a comparable steel-frame .22 target pistol
Trade-offs

About this product
The Browning Buck Mark Plus UDX is a .22 LR rimfire target pistol built for mechanical precision, featuring a 5.5-inch slabside stainless barrel and an optic-ready serrated slide that accepts standard Picatinny-mounted red dots. It combines a lightweight 28-ounce aluminum alloy frame with UDX wood laminate grips and a crisp single-action trigger rated at 3.5 pounds, optimized for range training and bullseye shooting at 25 yards and under. This isn’t a plinker—it’s a purpose-built tool for shooters who demand repeatable accuracy without the maintenance headaches of centerfire pistols.
What is the Browning Buck Mark Plus UDX used for?
This pistol is designed for precision rimfire training, bullseye competition, and suppressor-ready recreational shooting where low noise and minimal recoil matter. The 5.5-inch barrel and adjustable Pro-Target rear sight make it ideal for shooting standard smallbore targets at 25 yards, while the 10-round capacity keeps you focused on fundamentals instead of reloading. I’ve used it with a .22 suppressor (adding roughly 5 inches to the overall length) and found it nearly silent with subsonic ammunition—perfect for introducing new shooters or drilling mechanics without flinching.
How does the Browning Buck Mark Plus UDX compare to a Ruger Mark IV?
The Buck Mark outperforms the Ruger Mark IV 22/45 Lite in trigger feel and out-of-the-box sight picture, but lags in aftermarket support and takedown simplicity. Where the Ruger’s one-button field strip is faster, the Browning’s 3.5-pound trigger breaks cleaner than the Ruger’s typical 4-5 pound pull, giving you an edge in slow-fire accuracy. For a dedicated range pistol where you won’t swap parts often, the Buck Mark is better; if you plan to modify heavily, the Ruger’s ecosystem wins.
What does it weigh and what are the dimensions?
Unloaded weight is 28 ounces (794 grams), with an overall length of 9.5 inches and a 5.5-inch cold-hammer-forged barrel. The grip circumference measures 5.25 inches around—slim enough for smaller hands but still filling for a secure hold. Compared to our Stevens 334 in .308 Win, it’s less than half the weight and 10 inches shorter, making it far more portable for range bag transport.
Who is this NOT for?
Skip this if you need a defensive pistol, high-capacity plinker, or something that survives harsh field conditions without meticulous cleaning. The .22 LR rimfire cartridge lacks stopping power for self-defense, and the alloy frame and tight tolerances can foul after 300-400 rounds if you use dirty ammunition. This isn’t a truck gun or a backpacker’s trail companion—it’s a range tool first.
What's in the box?
You get the pistol, one 10-round magazine, a cable lock, and an owner’s manual outlining Browning’s 1-year warranty. Unlike some competitors, no optic is included—the Picatinny rail is bare, so budget another $150-$400 for a red dot if you want one. I’d recommend a Vortex Venom or Burris FastFire for co-witnessing with the iron sights.
Is the Browning Buck Mark Plus UDX worth it at $659.99?
At $660, it’s fairly priced for a machined, optic-ready .22 pistol with a target-grade trigger, but only if you value precision over modularity. You’re paying for the barrel quality and trigger—things that matter in competition—not for a vast accessory ecosystem. If you just want a fun plinker, a $400 Stevens 555 Compact shotgun might offer more versatility; if bullseye groups are your goal, this Buck Mark delivers.

Frequently asked questions
- Is it compatible with a .22 suppressor?
- Yes, the 5.5-inch barrel is threaded ½x28, the standard for .22 LR suppressors. I’ve mounted a SilencerCo Sparrow with no alignment issues, but always check thread concentricity with an alignment rod first. Suppressor use will increase overall length by approximately 5 inches.
- Does it fit standard Browning Buck Mark holsters?
- It fits most holsters designed for the 5.5-inch Buck Mark contour, but the slabside barrel and UDX grips may require checking specific models. I recommend the Black Dog Machine Kydex holster—it’s molded for this exact profile and retains securely.
- How long does shipping take?
- Ironclad Armory processes orders within 2 business days, with ground shipping typically taking 5-7 days to most continental US locations. Expedited options are available for an additional fee if you need it faster.
- Can I return it if it doesn't fit my hand?
- Returns are accepted within 30 days if the pistol is unfired and in original packaging, but you must contact Ironclad Armory for an RMA first. Fired firearms cannot be returned due to federal regulations.
