The 640 Pro is yet another in Smith & Wesson’s seemingly endless line of small revolvers. Two things distinguish the 640 Pro from Smith & Wesson’s inexpensive mass market J-frame revolvers like the 642. First, the 640 Pro is a real stunner of a gun, crafted of the most luxurious stainless you’re likely to see. Second, one can buy two 642s for the price of one 640 Pro, with enough change left over for dinner for two at the 99.
Continuing the fly-by, it’s hard to miss the sights that embellish the 640 Pro. Unlike the vestigial and almost useless sights on a typical J-frame revolver, the 640 Pro sports actual gunsights fore and aft. Both front and rear sights are dovetailed and drift adjustable by anyone who owns a punch and a hammer. And these are not just any sights. Smith & Wesson opted to embellish this revolver with Trijicon® tritium night sights. Literally standing above typical J-frame sights, these Trijicons never snagged in my IWB or pocket holster. Obviously, Smith & Wesson intended the 640 Pro for something more than a gunfight in a phone booth.
The rest of the revolver is pretty much conventional J-frame, which is not a bad thing. The 640 Pro boasts the high quality fit and finish for which Smith & Wesson revolvers are known. Even the point-and-shoot handle geometry is the same, just with a larger grip. The 640 Pro is equipped with removable full grip that should please ham-handed shooters. The handle offers a significant edge in leverage over the two-finger grip attached to most snubbies, but the difference doesn’t stop there.

Be advised that loading the moon clips with most brands of ammo was easy, but I struggled with one brand in particular. Depending on whether a shooter uses the supplied or aftermarket clips, it might be that some brands of brass or steel won’t fit as readily into the moon clips as might others. However, once loaded into the clips, all the brands of ammo that I tried functioned without flaw.
The sights that looked so impressive during pre-flight functioned slightly less impressively. Although the Trijicon sights are absolutely a step up from the pitiful sights on most J-frame revolvers, I found the three tritium dots to be too small for rapid target acquisition. The front sight was especially difficult to use. I ended up ignoring the dots and aligning the revolver as if I was shooting with plain patridge sights. Not connecting the dots proved to be faster than aligning them as they were meant to be used, and actually improved accuracy.

The trigger was about what I expected from a Smith & Wesson snubby. It was smooth to be sure, but as heavy as a Christmas fruitcake. Conan might be able to press this trigger with the pad of his pinky finger, but I had to use the power crease of my trigger finger. Using the distal joint changes the finger action from a press to a curl, which can lead to inaccuracy. Which is what I got.
I would also have given myself tendonitis. The 640 pro’s trigger was far too heavy to get a smooth pull with the pad, forcing me to use my “power crease.” Blasting away at the target and point shooting, I was able to craft this interesting string.
While one can say that the problem was with me and not the gun, the fact remains that a fancy shootin’ iron like the 640 Pro should facilitate accurate speed shooting, not impede the same.

Firing full-on .357 Mags proved to be an exercise in pain management. The covered backstrap wasn’t covered enough. The grip coverage does not extend to the top ½” of the backstrap, which is exactly where the web of my hand would like to be located. The same web that was deliriously happy shooting .38s suffered an unpleasant stinging sensation firing .357s. I countered that problem by taking a lower grip, which was well under the bore axis. With .38s a low grip was no issue. Unfortunately, the lower grip position allowed extra muzzle flip when shooting .357s, so it took me too much time to get follow-up shots on target.
For my last bitch, I found “Smith & Wesson Model 640 Pro Series” to be a tad cumbersome in both name and weight. I was able to change the former to “640 Pro,” which seemed to roll trippingly off the tongue or the keyboard, as the case may be. But there was nothing I could do about those 24 ounces.
All things considered, Smith & Wesson’s Model 640 Pro Series reminds me of a girl I dated way back in college during the Pleistocene Era. Like the gun, she was flashy, beautiful and comfy to hold. In the end she promised more than she could deliver. And in retrospect, she too was probably just a bit overweight.

RATINGS (out of five stars)
Style * * * *
Droolworthy style touches, such as the elegant fluted barrel and tapered underlug, dress up this revolver. The finish, which looks so sexy in the box, is hard to keep looking good after a day at the range. Owners will want to invest in many forms of exotic cleaning solutions and use them frequently, or suffer the consequences.
Ergonomics (carry) * * * 1/2
With its full-sized grip, it fits into a pocket but not as comfortably as it should. Swapping the full-sized grip for a smaller boot grip (standard on many other J-frame revolvers) would improve concealment to the detriment of handling, especially shooting .357 Magnums. Although it conceals well in an IWB holster, it feels a little heavy.
Ergonomics (firing) * * * 1/2
Recoil with .38 SPLs is almost pleasant; shooting .357s from such a small revolver is an exercise in self-abuse. The tritium dot front sight is easy “lose” when firing rapidly and hard to see at all times. The rear sight is better, but both sights would benefit greatly from larger dots.
Reliability * * * * 1/2
Expect “five for sure” – but wipe it down from time to time, okay? The finish attracts dirt like a Swiffer duster and allowing carbon and dust to accumulate near the crane or hand is begging for trouble.
Customize This * * *
J-frame revolvers can be accessorized with fancy grips, enhanced with laser sights or personalized with engraving. That’s it.
OVERALL RATING * * * 1/2
Firing .357 Mags, the 640 pro has a high “power to weight” ratio. However, it’s too heavy to be called a lightweight, and too light to shoot Magnums comfortably. It shoots .38s like they were .22s, but for half the price, a .38 Spl. Centennial Airweight would be a better choice.
