## What Customers Say

*AI-generated insights from customer reviews*

Owners of the Rock Island STK100 consistently point to value as the reason they bought it. Build quality and reliability get positive marks, and the 17-round capacity is noted as a practical feature at this price point. Grip comfort and ergonomics come up positively for longer range sessions.

The trigger is the main criticism. Several owners describe it as heavier or less refined than competing pistols, particularly in double-action mode. Aftermarket support is also noted as limited, which matters to buyers who like to customize.

The overall picture is a pistol that punches at its price, with trigger feel as the most common trade-off.
