About the Smith & Wesson Model 940-3 9mm J-Frame Snub Revolver
Quick Answer
The S&W Model 940-3 is a DAO 9mm Luger J-Frame snub revolver with a 1.875" barrel, 5-shot capacity, concealed hammer (snag-free), moon-clip compatible cylinder, textured synthetic grip, matte black finish, ~14.4 oz unloaded, ~6.3" OAL, ~1.3" width. Returns to S&W's catalog in 2026 after a long absence.
What Makes the Model 940-3 Stand Out
Smith & Wesson's J-Frame is the most refined small revolver platform in American production history. The 940-3 sits on that foundation with a specific caliber twist: it chambers 9mm Luger rather than the traditional .38 Special or .357 Magnum you'd expect in a J-Frame snub.
Why 9mm in a revolver? Ammunition commonality. If you carry a 9mm semi-auto as your primary gun — and the majority of defensive handgun carriers do in 2026 — you can now run the same ammunition in your backup revolver. The Model 940-3's cylinder is moon-clip compatible, which solves the headspace challenge that comes with running a rimless cartridge in a revolver. Moon clips also speed reloading significantly — instead of feeding cartridges one by one, you load all five rounds simultaneously in about two seconds.
The concealed hammer is the detail that makes this a true EDC tool. External hammers on snub revolvers catch on clothing during a draw — fabric, a jacket lining, a pocket seam. A concealed (fully internal) hammer eliminates that problem. The double-action-only trigger pull is the only way to fire the gun, which also means there's no accidental cocking in a pocket holster. The tradeoff is a heavier, longer trigger pull — typically 10–12 lbs on a J-Frame DAO — which takes more finger strength and practice to shoot accurately, but is widely accepted as the right balance for a close-range defensive pocket gun.
At 14.4 oz unloaded and 1.3" wide, the 940-3 is genuinely pocketable in cargo pants, a jacket pocket, or a quality pocket holster in larger jeans. The 6.3" overall length keeps it shorter than most compact semi-autos. If you're comparing it to a micro-compact like the Taurus GX4 XL 9mm, the revolver is slightly thicker but shorter front-to-back, and it doesn't have a slide that can catch fabric during a pocket draw. Different compromises for different carry styles.
The matte black finish reduces light signature. The textured synthetic grip fills the hand adequately for 5-round defensive use — it's not a target grip, and it's not meant to be. The low-profile fixed sights are appropriate for a defensive snub at the ranges where this gun would actually be used: under 10 yards. You're not punching paper at 25 yards with this revolver. You're carrying it every day so it's there when you need it.
S&W brought the 940-3 back to catalog in 2026 after a long absence from production. Original Model 940 revolvers from the early 1990s appear regularly on the used market, but getting a new-production example with a warranty is a different proposition. For buyers who want the dependability of a new-production S&W J-Frame with the 9mm caliber advantage, the timing of this reintroduction is well-placed.

How It Compares
The Chiappa Rhino 60DS 10mm represents the opposite end of the revolver design philosophy — a 6" barrel, 10mm chambering, 6-shot capacity, and a barrel that fires from the bottom cylinder rather than the top. The Rhino is a full-size revolver designed for range use and power. The S&W 940-3 is a pocket-sized 9mm with 5 rounds and minimal mass. They share the revolver action type but serve completely different roles.
Honest Pros and Cons
Pros:
The concealed hammer and DAO-only action makes this the most pocket-carry friendly revolver configuration available — no external parts to snag on clothing during a draw. Running 9mm Luger means ammunition commonality with the most popular defensive pistol caliber in the U.S. Moon clips enable fast reloads and solve rimless cartridge headspace completely. New-production S&W J-Frames come with the factory warranty and quality control of current production — not a used gun with unknown round count.
Cons:
Five rounds is all you get without a reload — that's a real capacity limitation compared to a micro-compact semi-auto that runs 10–15 rounds. The DAO trigger pull of approximately 10–12 lbs requires consistent dry-fire practice to shoot accurately; new shooters often find J-Frame snubs harder to shoot well than a semi-auto with a lighter, shorter reset. Moon clips are required to properly headspace 9mm — carry spares and don't lose them at the range.
