Browning Buck Mark Standard URX .22 LR vs Ruger Mark IV Standard .22 LR

These two are the canonical entry-level rimfire target pistols, and they take opposite paths to the same job. The Mark IV runs a 6" barrel in a 10.25" frame at 30.1 oz; the Buck Mark is 0.75" shorter overall at 9.5" with a 5.5" barrel but carries 3.9 more ounces at 34 oz, since its monolithic steel receiver-and-barrel is a single rigid unit rather than a separate slide-on-frame design. Capacity is tied at 10+1. Both ship with adjustable rear sights from the factory — the Buck Mark uses Browning's Pro-Target rear with an 8" sight radius and a published 5.0 lb trigger; the Mark IV Standard uses an adjustable rear with a fixed front blade and a stock pull most owners report around 4 lbs with notable creep.

Pick the Browning Buck Mark Standard URX if:

• You want the longer 8" factory sight radius from a shorter overall pistol — Browning's Pro-Target rear sits at the back of the slab-sided receiver, stretching radius without lengthening the gun
• You prefer the monolithic receiver-barrel design, which removes slide-to-frame fit as a variable in mechanical accuracy across the gun's service life
• You want the Ultragrip RX overmold for sweaty-hand retention without buying aftermarket grips

Pick the Ruger Mark IV Standard if:

• You want the largest aftermarket in the .22 LR target pistol category — Volquartsen, Tandemkross, and Clark offer complete drop-in triggers, barrels, and grip frames with no machining
• You prefer 3.9 oz less weight (30.1 oz vs 34 oz) for less hand fatigue across long range sessions
• You want the one-button takedown that drops the upper for cleaning in under two minutes — the Buck Mark requires a more involved disassembly

Both are American-made single-action rimfires with 1:16" twist barrels, equivalent 10-round capacity, and adjustable rear sights from the factory. The Mark IV ships with two magazines; the Buck Mark ships with one. The cleanest decision criterion is whether you want the Buck Mark's longer factory sight radius and monolithic receiver, or the Mark IV's lighter weight, deeper aftermarket, and one-button takedown.
