Defensive Use of the Smith and Wesson Airweight Revolvers:

Probably 99% of Airweight revolvers are purchased as defense guns, and the majority of those are used as carry guns. That's only natural, as the light weight and small size of these revolvers lend themselves pefectly to carry.

If you're choosing a gun for carry, you might want to consider more than just the gun itself. For example, the majority of defensive shootings happen at night or in low light, where the criminal thinks he has an advantage. Even if your revolver has night sights, you may find it difficult to engage your target quickly.

Devices such as Crimson Trace laser grips make aiming in low light so easy that it's almost automatic. Crimson Trace laser grips on a Smith and Wesson Airweight revolverOnce the laser dot is on the target, you know where your shot will go if, heaven forbid, you have to shoot. The Crimson Trace laser grips don't alter your grip on the pistol, as they're patterned after the factory grips. They don't add more than a fraction of an ounce of weight. What they do add is the ability to got on target fast and dependably. If you're looking for one accessory that will help you the most in a defensive shooting situation, a laser sight is probably it.

Given that the Airweight revolvers hold five rounds, you just might find yourself needing more. That's why it's a good idea to carry a speedloader with extra rounds. A speedloader will fit in your pocket or in a pouch without weighing you down, yet gives you five additional rounds--or ten or fifteen if you choose to carry more than one speedloader.

There are several brands of speedloaders on the market. Some require twisting a knob to release the cartridges into the cylinder. Others require the user to push on the top of the speedloader. Use whatever you feel most comfortable with, but be sure it's a quality product. You don't want to skimp on defensive devices.

Smith and Wesson 638 Airweight Reviews:

Overall Rating: review stars, 5 out of 5 possible stars 5 out of 5
By Kevin, Lawrence, KS

Purpose: Defense/Law Enforcement

"Just picked up this little gem last week. I've fired about 100 rounds of range ammo through it. I love it. I got the 637 model with the snubby barrel. A lot of fun to shoot and surprisingly not bad recoil. I just ordered some walnut grips for it. I'm a big fan of wood grips even though it now won't allow me to add a crimson trace. I pocket carry this as my only defense weapon in the warm months and carry my 9mm in a paddle holster the other months of the year."
