Well, I do have a few AirLite Smith & Wesson firearms.
Starting with the more unusual stuff is my SW40Ti. This is the mythical Titanium SIGMA. I have only seen one but I heard that 5 were made. The Titanium slide saves quite a bit of weight. The stainless steel brothers and sisters weigh in 20% heavier.
My 625Sc revolvers are so cute. I just had to have a NY reload. 45 Colt in these little guys make this a GREAT fighting revolver.
I do love the 8 shot 327s. I bought both the 2" barreled 327 Carry and the 5" barreled 327 JM.
Now we come to my favorite caliber........41 Magnum. I have one of the 357PDs as well as a Taurus 415 Total Titanium. I know it is not a S&W, but it is a nice 2 1/2", 5 shot, K-frame sized revolver that weighs in at 19 ounces.
Of course, there has to be a 386PD. What a great L-frame snubby. Mine has the C&S Extreme Duty rear sight in place of the traditional S&W adjustable.
And last but not least, I have a 340PD for pocket carry in shorts or other light clothing. Sorry, but the only photo that I have of this one is nestled i with some other J-frames including the model 317 which is not a Sc, Ti or PD, however, it is one of the lightest S&W revolvers ever made. The aluminum frame and cylinder drop it down to 10 ounces.
