Features 

The 5.7x28mm cartridge runs at high velocity with noticeably less felt recoil than larger-bore pistol calibers, which makes rapid follow-up shots easier to manage. At 24.5 oz, the gun is light for its size. The 20+1 capacity gives you more rounds on tap than most full-size pistols without a significant weight penalty. 
 
Dimensions are on the larger side — 8.65" overall — so holster fit and concealability should be confirmed before buying for carry. Ergonomics are generally well-regarded, and the trigger pull is smooth. 
 

Usage 

• Sport shooting and competition where high round count and fast follow-ups matter 
• Home defense, where the 20+1 capacity and manageable recoil are practical advantages 
• Range training, particularly for shooters working on recoil management

The Ruger 57 in Desert Earth gets a generally positive reception, with a few recurring practical concerns worth knowing before buying.

The 5.7x28mm caliber is where opinions split most. Enthusiasts like the low recoil and high velocity, and the round does well in both target shooting and defensive roles. The consistent pushback is about ammunition: 5.7x28mm costs more per round than 9mm and is less stocked at most retailers, so it matters if you plan to shoot it regularly.

Accuracy gets consistent praise. Most users find the gun easy to shoot well thanks to the light recoil and smooth trigger. The 20+1 capacity is widely cited as one of the better selling points — it is genuinely higher than comparable pistols in the same class.

Reliability is mostly fine, but some users have noted issues during break-in or with specific ammunition types. The general recommendation is to run a variety of factory loads early and see what it likes.

Price is a recurring topic. The Ruger 57 sits above mid-tier pistols, and some buyers feel the premium is justified by the capacity and caliber novelty, while others think the higher-than-average ammo cost erodes the value over time.

Overall, it is a well-built pistol with a niche caliber. If you are comfortable sourcing 5.7x28mm ammo and the capacity matters to you, it holds up. If you are budget-sensitive on consumables, factor in the ongoing ammo cost.
