Browning Buck Mark Contour Pro .22 LR 5.9in G10 Grip
Pros & cons
What works
- Factory-threaded 1/2×28 muzzle — ready for a suppressor without $150+ gunsmithing
- 34 oz unloaded weight — 6 ounces lighter than a Ruger Mark IV Target with a similar barrel length
- Drilled and tapped receiver with integral Picatinny rail — accepts optics immediately, no adapter needed
- G10 grips provide aggressive texture — superior grip in wet conditions versus standard checkered wood
Trade-offs
- Takedown requires a 3/32" hex key (not included) — more complex than the Ruger Mark IV's one-button system
- Single 10-round magazine included — most competitors include two, adding $35-40 for a spare
- Alloy frame shows wear faster than stainless steel — holster use will reveal holster marks within months

About this product
What is the Browning Buck Mark Contour Pro .22 LR 5.9in G10 Grip? It is a purpose-built autoloading rimfire pistol engineered for precision target shooting and suppressor-ready recreational use. This pistol represents a specific evolution within Browning's Buck Mark series, focusing on a balance of ergonomic contour, accessory-ready mounting, and the mechanical reliability required for consistent rimfire performance. It's designed for shooters who need a platform that bridges casual plinking and serious, repeatable accuracy work without the bulk of a full competition rig.
What is the Browning Buck Mark Contour Pro used for?
The primary use is precision target shooting and suppressed rimfire training. This pistol's 5.9-inch barrel provides a sight radius conducive to accuracy, while its drilled/tapped receiver and 1/2×28 threaded muzzle make it an immediate host for optics and suppressors like the Dead Air Mask or Rugged Oculus. The G10 grips and adjustable sights solidify its role as a tool for refining fundamental marksmanship skills, especially for new shooters or those maintaining proficiency with a low-recoil, low-cost caliber.
How does the Browning Buck Mark Contour Pro compare to the Ruger Mark IV 22/45?
The Browning offers a superior out-of-the-box trigger and a more refined ergonomic contour compared to the utilitarian Ruger Mark IV 22/45. Where the Ruger excels with its single-button takedown for effortless cleaning, the Browning's traditional takedown via a hex key is more involved. For a shooter prioritizing a crisp, 2.5-pound break from the factory and immediate optic mounting, the Buck Mark Contour Pro is the better choice; for those who value maintenance simplicity above all, the Ruger holds the advantage.

What does it weigh and what are the dimensions?
Unloaded, the pistol weighs 34 ounces (964 grams), with an overall length of 9.5 inches. The 5.9-inch barrel is cold hammer-forged and features a 1:16 right-hand twist rate, optimized for standard and high-velocity .22 LR ammunition. Its balance point sits just forward of the trigger guard, giving it a neutral, pointable feel that rivals many full-size centerfire pistols in hand, despite its lighter projectile.
Who is this NOT for?
This pistol is not for the budget-first plinker seeking the absolute cheapest .22 pistol, nor for anyone intimidated by basic mechanical maintenance. Its $699.99 MSRP positions it above entry-level options, and its takedown procedure requires a 3/32-inch hex key and attention to detail—it's not a tool-free field-strip design. If your sole requirement is a box-fed .22 for pest control at minimal cost, a rifle like the Stevens 334 in .243 Win offers more terminal energy for a similar price.
What's in the box?
The package includes the pistol, one 10-round steel magazine, a fitted pistol rug for storage, and the necessary thread protector for the muzzle. Notably absent is the hex key required for disassembly—a cost-saving measure that assumes the end user has a basic armorers kit. The optic rail is pre-installed, and the rear sight is fully adjustable for windage and elevation, ready for a 25-yard zero straight from the factory.
Is the Browning Buck Mark Contour Pro worth it at $699.99?
Yes, for the shooter who values a precision-focused rimfire platform ready for optics and suppressors without aftermarket modifications. You are paying for the hand-contoured alloy frame, premium G10 grips, and Browning's proven target-grade action in a configuration that avoids the $150-200 in gunsmithing fees typically required to thread a barrel and mill a slide. Compared to building a similar setup from a base model, this represents a consolidated, warranty-backed value for serious rimfire enthusiasts.

Frequently asked questions
- Is the muzzle thread compatible with standard .22 LR suppressors?
- Yes, the 1/2×28 thread pitch is the industry standard for .22 caliber suppressors. It will directly interface with models from SilencerCo, Dead Air, Rugged, and most other major manufacturers without an adapter. Ensure your suppressor is rated for .22 LR and follow all NFA regulations for possession.
- What optic footprint does the top rail use?
- The integrated rail is a standard Picatinny/MIL-STD-1913 specification. It will accept any red dot sight or scope with a Picatinny clamp, including popular micro dots like the Holosun 507C or full-size optics. No proprietary mounting plates are required.
- How many rounds does the magazine hold?
- The included magazine has a 10-round capacity, which is the standard for most Buck Mark models. Aftermarket 10-round magazines from Browning are readily available, but higher-capacity magazines are not commonly manufactured due to the pistol's single-stack design.
- Does it ship with a thread protector?
- Yes, a blued steel thread protector is installed on the muzzle at the factory. It should be removed only when attaching a muzzle device or suppressor. We recommend applying a small amount of high-temperature thread locker, like Rocksett, to the protector to prevent it from loosening during firing.
- What is Ironclad Armory's return policy for firearms?
- All firearm sales are final upon transfer to your licensed dealer (FFL). If a manufacturing defect is discovered during your inspection at the FFL, you must refuse the transfer and contact Ironclad Armory support within 24 hours to initiate a warranty replacement. We do not accept returns for buyer's remorse or change of mind due to federal regulations.
- Can I use CCI Stinger or other hyper-velocity .22 ammo?
- Browning recommends standard and high-velocity .22 Long Rifle ammunition. While the action may cycle hyper-velocity rounds like CCI Stingers, the increased pressure and differing case length can accelerate wear on the extractor and are not ideal for sustained target accuracy. For best results, stick with ammunition rated under 1,300 feet per second.
