Owners of the Grand Power Q1 MK23 consistently bring up the rotating barrel system as the platform's defining characteristic, crediting it with reducing perceived recoil during rapid fire. The 15-round capacity hits a practical number for a compact pistol, and owners note the magazines feel well-made and feed reliably.

The Q1 MK23 gets good marks for its overall fit and finish, which owners find competitive with better-known European pistols. Ergonomics are a consistent positive, though shooters accustomed to American double-stack pistols sometimes need a few range sessions to adapt to the grip angle and control placement. The trigger draws a range of opinions: some owners call it a strength of the platform, others find the reset takes adjustment.

The most repeated owner concern is aftermarket support. Holster options are limited, and sourcing additional magazines outside of what comes in the box can be frustrating. Grand Power's distribution in the US is narrower than mainstream brands, which affects both parts availability and resale value.
