Description
The Model 642 has been the default answer to "what should I carry?" for decades, and this CT version solves the one thing snub-nose revolvers have always struggled with: a short sight radius. The Crimson Trace LG-305 Lasergrips come installed from the factory, and the activation button sits right in the front of the grip where your middle finger naturally lands. Take a normal firing grip and the red dot is already on target. No switches to hunt for, no extra step to remember when things get stressful. That matters in low light, from awkward positions, or any time you cannot get the gun up to eye level.
Why the 642 CT Airweight Earns Its Pocket Space
The Airweight name is not marketing fluff. The aluminum alloy frame keeps this five-shot .38 Special at roughly 15 ounces, light enough that you stop noticing it in a pocket holster or on your belt. The stainless steel barrel and cylinder shrug off the humidity and sweat that come with close-to-the-body carry, and the matte silver finish stays looking clean without babying. The fully enclosed hammer is the other half of the story. There is nothing to catch on a jacket lining or pocket edge on the draw, and the double action only trigger means operation comes down to point and press.
A .38 Special J-Frame Rated for +P
This 642 is rated for continuous +P use, so you can carry the stouter defensive loads and practice with them too. It also ships without an internal lock, which a lot of revolver folks specifically seek out for a cleaner action and simpler mechanism. The integral front sight and fixed rear notch give you a rugged backup if the laser battery ever runs down, though the Lasergrips run a long time on a set of batteries and hold zero once dialed in.
Set Up for Carry Right Out of the Box
Between the weight, the smooth profile, the laser, and the +P rating, there is nothing to add before this revolver goes to work. Load five rounds, confirm the laser zero at the range, and it is ready to ride wherever you go.

Frequently Asked Questions
How does the laser on the 642 CT turn on?
The Crimson Trace LG-305 Lasergrips use instinctive activation. A pressure button sits in the front of the grip right where your middle finger rests, so the red laser comes on automatically when you take a normal firing grip. There is also a master on/off switch on the grip if you want to shut it down for dry practice or storage.
Can the Smith & Wesson 642 CT handle +P ammunition?
Yes, this model is rated for continuous use with .38 Special +P loads, not just occasional carry ammo. That means you can practice with the same hotter defensive rounds you carry. Standard pressure .38 Special works fine too and is noticeably softer to shoot in a gun this light.
Does this 642 have the internal lock?
No, this version (MPN 150972) ships without the internal lock system. Many revolver buyers specifically look for the no-lock configuration for its cleaner sideplate appearance and simpler internals. It still includes a standard cable lock in the box for storage.
Is the 642 CT Airweight good for pocket carry?
It is one of the most popular pocket revolvers ever made for good reason. The fully enclosed hammer means nothing snags on the draw, the alloy frame keeps it around 15 ounces, and the Lasergrips add very little bulk. Pair it with a proper pocket holster that covers the trigger guard and it disappears into most pants or jacket pockets.
