In today's "tacticool" world, high capacity, plastic, semi-autos seem to be all that is talked about in the gun rags as well as on many forums. Yet if you were to check with with those who "have seen the elephant" it seems many carry a short barreled revolver as a back-up, or in some cases as a primary when a pocket gun is called for. Why? The answer is simple enough...they work. While no firearm (or anything made by man) is 100% reliable 100% of the time, the revolver when made by a reputable company comes closer than any other type of action. When loaded it can sit for years with all springs is a resting position. Shrouded or hammerless versions can be fired from inside a coat pocket. It comes in a variety of calibers that anyone can handle from the lowly 22 rimfire up through the mighty 44 magnum and beyond. While many of the 5 shot, 2 inch snubbies are fixed sights, the slightly larger 6 shot 2 1/2 inch barrel guns come with adjustable sights and all are capable of minute of felon accuracy. They can also be very lightweight, scandium frame J-Frame S&W weighs in at 12 ounces. Even my N-Frame 45ACP 325PD weighs in 4 ounces shy of 2 pounds.
Accuracy is one of the issues that always crops up when snubbies are discussed. I have heard "they are accurate out to 10 feet" many, many times and have never understood that. Trust me the bullet doesn't go 10 feet then turns left. While the shorter sight radius makes being accurate a longer ranges more difficult it is a simple matter of practice. Actually if you look at the traditional pocket semi-autos the sight radius on the snubbies is actually as long or longer and quite often the sights are larger and easier to see on the revolvers. Even with the fixed sight 2 inch guns it is not that hard to keep all shots center mass on a FBI qualification target at 25 yards with just a bit of practice.
Today the selection of available snubbies is quite large as well. S&W alone offers dozens of variations and the market is solid enough Ruger recently introduced a snubbie. Other makers include Taurus, Rossi, Charter but I do recommend sticking with the US made versions. Also on the secondary market many Colts are still available both in the 2 inch D-Frame as well as the 2 1/2 inch J-Frame guns. And while prices tend to run hi9gher than some of the cheaper semi-autos such as the Kel-Tec they are inline with semi-autos of similar quality.
Here is a short list of pros and cons regarding the snubby, this is not a complete list nor is it meant to be...it is just the highlights:
Pros:
lightweight
many different calibers from light to heavy
shrouded or hammerless can be fired from inside a coat pocket
easy to conceal
if a round fails to fire simply pulling the trigger brings a fresh shell into play
will function even when in contact with the target
easy to make safe at home
easy to check to see if loaded
same trigger pull for every shot
ease of loading, unloading
very simple manual of arms
Cons:
lower capacity than many semi-autos
slightly wider depending on caliber
can be slower to reload (with practice this can be alleviated for the most part)
longer trigger pull in many cases (again practice negates this)
heavier trigger pull in some models versus a SA semi-auto
exposed hammer models can snag if you don't recognize the problem and dress for it (avoid jackets with mesh linings)
speedloaders are bulky (I used speedstrips quite often)
The vast majority of self defense shootings occur at near toe to toe distances, what is often described as ECQ (extreme close quarters). The firearm used needs to be as operator proof as possible meaning the simpler it is to use the better. In a stress situation it is too easy to miss swiping off a safety, in contact shooting a semi-auto can easily be pressed out of battery, will likely only fire one round when shot from inside a coat pocket, may suffer from a failure to feed/extract if the slide's movement is impaired. The revolver works many times in situations that will reduce a semi-auto to a single shot that has to be manually operated for a second shot.
I would also say I am not anti semi-auto, I own and carry several including Glock, H&K, Kel-Tec, Browning, and Colt. But the simplicity and reliability of the revolver appeals to me and the snubbies are easy to carry and easy to conceal. Whether in a coat pocket, pants pocket, belt or shoulder holster the snubbie fits very well. It also hides well in purses, fanny packs, even more unusual carry methods like the Kramer Confidential T-Shirt. Of course semi-autos also carry well in these positions but the point is a revolver carries as easy as the semi-auto and the short barrel makes concealment easy.
Currently I utilize mainly three snubbies for daily carry. They are a S&W 325PD, a 45ACP revolver that uses full moon clips to hold the ammunition. For carry I also use 45 auto rim in speed strips. Two of these fit nicely in a belt pouch and looks like a cell phone case. Second snubby is my old model Detective Special with an original Colt Hammer shroud. This gets carry time on the belt, in the pocket and with winter approaching will get a good amount of time in my coat pocket. On the bottom is a Model 12, an airweight K-Frame. This also gets both pocket and belt carry and I like the fact it is a six shot rather than 5 like the standard J-Frames in 38. Quite often all three of these will be carried at the same time. Also shown id the best book written on the subject of the snub nose revolver, "The Snubby Revolver" by Ed Lovette. I recommend this book to anyone who carries are snubby or is looking for a small gun.

Perhaps it is my advancing age but I find that simpler is almost always better. The revolver is a simple firearm with fewer steps involved in it firing cycle. The fewer things that must happen is sequence for anything mechanical to work is always a good thing as there are fewer things to go wrong. The snub nosed revolver is a robust simple tool in today's high tech world. I absolutely love my H&K P7M8 but despite the fact it has always worked I still have more confidence in my revolvers. My Kel-Tecs have always worked nearly flawlessly but the revolver still feels better in hand.
Don't discount old school when looking for that perfect pocket gun, the older I get the more I realize old does not mean outdated.
