The Smith & Wesson 340PD AirLite .357 Mag 1.88″ 5rd No Lock is a lightweight J-Frame revolver built for serious concealed carry. It weighs just 12 ounces empty thanks to a scandium alloy frame and titanium cylinder, letting you carry full-power .357 Magnum loads without the bulk of a steel gun. This no-lock version eliminates the internal lock for a cleaner sideplate and one less potential failure point.

Key Features
- Scandium alloy frame — WHY IT MATTERS: Keeps the revolver under a pound while handling .357 Magnum pressures, so you get serious stopping power in a pocket-friendly package.
- Titanium cylinder — WHY IT MATTERS: Sheds ounces compared to steel cylinders and resists corrosion, critical for a daily carry piece that sees sweat and humidity.
- Enclosed hammer — WHY IT MATTERS: Snag-free draw from pocket or waistband holster. No hammer spur to catch on clothing during a defensive presentation.
- Red ramp front sight — WHY IT MATTERS: Gives you a fast, visible sight picture in low-light or high-stress situations, cutting down acquisition time.
- No internal lock — WHY IT MATTERS: Removes a potential failure point and gives the sideplate a cleaner, more reliable design. Preferred by many CCW holders who don’t want a keyed lock on a defensive gun.
Who It’s For
This revolver is for the CCW holder who wants maximum concealability with minimum weight. It fits deep-cover roles: ankle holsters, pocket carry, or as a backup to a semi-auto. It’s also a solid choice for home defense if you prefer a revolver’s simplicity under stress — point and press the trigger, no safeties to fumble.
Pros & Cons
- Pro: Ridiculously light for a .357 Magnum. Carries all day without dragging your belt down.
- Pro: Snag-free profile and enclosed hammer make it one of the smoothest drawing revolvers on the market.
- Con: Recoil with full .357 Magnum loads is sharp — the lightweight frame transfers energy directly to your hand. Practice with .38 Special +P to stay proficient and save your palm.
Comparison
| Feature | Smith & Wesson 340PD | Ruger LCR .357 | Kimber K6S DASA |
|---|---|---|---|
| Weight (empty) | 12 oz | 17.1 oz | 23 oz |
| Capacity | 5 rounds | 5 rounds | 6 rounds |
| Frame material | Scandium alloy | Polymer | Stainless steel |
| Barrel length | 1.88″ | 1.875″ | 2″ |
| MSRP | $1,140.31 | $719 | $1,099 |
The Ruger LCR is heavier and less expensive but has a polymer frame that can feel less rigid under magnum loads. The Kimber K6S holds an extra round but weighs nearly twice as much, making it less ideal for pocket carry.
FAQ
Can this revolver handle .357 Magnum loads without damage?
Yes. The scandium alloy frame and titanium cylinder are rated for .357 Magnum pressures per Smith & Wesson’s specs. That said, the lightweight build means recoil is stout — many shooters run .38 Special +P for practice and carry .357 for defense.
How does the no-lock version differ from the standard 340PD?
The no-lock version omits the internal lock mechanism found on some J-Frames. This means one less part that could fail, a smoother sideplate, and no key required. It’s a popular choice among CCW holders who prioritize simplicity.
What holsters work with the 340PD?
Any holster designed for a 1.88″ barrel J-Frame with an enclosed hammer fits. Pocket holsters, ankle rigs, and IWB holsters from brands like DeSantis, Galco, and CrossBreed are common choices. Since the hammer is enclosed, you don’t need a hammer shield.
Is this revolver suitable for beginners?
It can be — but the light weight and .357 Magnum recoil make it challenging for new shooters. Start with .38 Special +P loads to build familiarity, then move up to .357 once you’re comfortable. The simple revolver operation (point and shoot) is beginner-friendly in terms of manual of arms.
