Description
Pick up the Smith & Wesson 340PD and the first thing you notice is what you don't feel. At 11.4 ounces unloaded, this J-Frame weighs less than most loaded pocket pistols, yet it chambers full power .357 Magnum. That's the whole point of the AirLite build. The frame is scandium alloy, the cylinder is titanium, and the barrel is stainless steel under that matte black finish. Smith & Wesson essentially built the lightest .357 they could without giving up the strength the cartridge demands.
Why the 340PD AirLite Disappears in a Pocket
This is a Centennial style frame, meaning the hammer is fully enclosed. There's nothing to catch on a jacket liner or pocket holster on the way out, and you can even fire it from inside a coat pocket if things ever go sideways. The double action only trigger keeps operation dead simple: pull, bang, repeat. A red ramp front sight sits over a fixed rear notch, giving you a quick, uncluttered sight picture at defensive distances. The synthetic grip fills the hand better than you'd expect on a gun this size, and the 6.3 inch overall length rides comfortably in a pocket rig, ankle holster, or on the belt.
No Internal Lock, No Complaints
This particular version, model number 103061, ships without the internal lock, and that flat sideplate is exactly what a lot of revolver folks have been waiting for. Cleaner look, simpler mechanism, classic J-Frame character. The cylinder holds five rounds and the gun runs .38 Special, .38 Special +P, and full house .357 Magnum, so you can train soft and carry stout. Plenty of owners practice with .38s and load magnums for carry, which is a sensible way to run a gun this light.
Living With the S&W 340PD
Fair warning from someone who has put rounds through one: magnum loads in an 11 ounce gun get your attention. That's the trade you make for a revolver you'll never leave home because of the weight. As a backup gun or a deep concealment piece, the 340PD earns its keep every single day, and it's backed by Smith & Wesson's lifetime service policy.

Frequently Asked Questions
Can the Smith & Wesson 340PD shoot .38 Special as well as .357 Magnum?
Yes. The 340PD is chambered for .357 Magnum, which means it also handles .38 Special and .38 Special +P without issue. A lot of owners do most of their range work with .38s and carry magnum or +P loads, which keeps practice sessions comfortable in a gun this light.
What does the no lock version of the 340PD mean?
This model, part number 103061, is built without the internal keyed locking mechanism found on many other S&W revolvers. That gives it a clean sideplate with no keyhole above the cylinder release and a simpler internal action. Many revolver enthusiasts specifically seek out the no lock J-Frames for exactly those reasons.
How is the recoil on the 340PD AirLite with full power .357 loads?
It's stout, no way around it. An 11.4 ounce gun firing magnum ammunition produces sharp recoil, which is the trade-off for a revolver this easy to carry all day. Most owners train primarily with .38 Special, verify their carry load works, and appreciate that light weight every time they holster up.
Why doesn't the 340PD have an exposed hammer?
It uses the Centennial style enclosed hammer, which makes the gun double action only and completely snag free on the draw. That's a real advantage for pocket carry, ankle carry, or backup duty since there's nothing to hang up on clothing. It also means the revolver can be fired from inside a coat pocket if needed.
