The design is rated for continuous +P use, allowing higher-pressure rounds without accelerated wear.

## What Customers Say

*AI-generated insights from customer reviews*

The Smith & Wesson 642 Airweight Lasergrip .38 Special +P gets positive reviews overall, particularly from carry-focused users.

The light weight is the most praised feature. At 15.5 oz, it carries comfortably all day in a pocket or IWB holster without adding noticeable bulk. Owners consistently mention the compact dimensions as a primary reason for the purchase.

Revolver reliability and mechanical simplicity draw strong endorsements. Fewer moving parts compared to semi-automatics means fewer failure modes, and owners who rely on it for defensive carry value that characteristic. The .38 Special +P capability gives owners access to effective defensive loads with manageable recoil.

The Crimson Trace Lasergrips divide opinion. Many owners credit them with improved accuracy under stress and for shooters with difficulty using traditional sights. A smaller group finds the laser activates too easily, leading to faster battery drain than expected.

Trigger pull criticism comes up with some regularity. The double-action only pull is on the heavier side and some owners pursue a trigger job or professional smoothing. The 5-round capacity is the other consistent criticism. Shooters accustomed to semi-automatic capacities note the limitation, though most carry-revolver users accept it as part of the tradeoff.
