PSA Rock 5.7 5.7x28mm vs Ruger-57 5.7x28mm

Two full-size 5.7x28mm pistols in the same weight class, 25.0 oz against 24.5 oz. The PSA Rock 5.7 5.7x28mm carries three more rounds (23 vs 20), breaks 1.1 lb lighter (3.5 lb vs 4.6 lb), is 0.58" shorter overall (8.07" vs 8.65") and lists $50 less ($499 vs $549). The Ruger-57 5.7x28mm is the better-equipped gun: it is optic-ready where the Rock is not, and it pairs a fiber optic front with an adjustable rear and an ambidextrous manual safety. The Rock uses Glock-compatible blade and square-notch sights.

Pick the PSA Rock 5.7 if:

• 23 rounds per magazine against the Ruger-57's 20
• The 3.5 lb trigger is 1.1 lb lighter than the Ruger-57's 4.6 lb
• MSRP is $50 lower ($499 vs $549)
• It is the smaller gun: 8.07" long and 5.35" tall vs 8.65" and 5.6"

Pick the Ruger-57 if:

• You want a factory optic cut; the Ruger-57 is optic-ready and the Rock is not
• An ambidextrous manual safety is part of how you carry or store a pistol
• A fiber optic front with an adjustable rear beats fixed Glock-pattern sights for you
• The 4.94" barrel is 0.24" longer, and it is the lighter gun at 24.5 oz

Capacity, trigger weight and price favor the Rock; the optic cut, adjustable sights and manual safety favor the Ruger-57. If you intend to mount a red dot, that alone decides it.
