Warning: Dirty joke below.
Many guys buy really large guns to compensate for their rather small ... you get the idea. Using that logic, I bought the smallest S&W there is. Here is a model 337. It weighs less than 12 ounces unloaded (the frame is an aluminum-scandium alloy, the cylinder is titanium, the only steel is a thin inner lining of the barrel). It fits into a tiny holster, and holds five 38SP+P rounds.
In this bad picture, it is equipped with a laser sight grip, which is sort of dumb; I usually have the original wooden grip on it. It is also quite unpleasant to shoot with full-power rounds, after a few dozen rounds I have blood blisters on the palm. And aiming it at distances larger than 7 yards is darn near impossible.
There are two guns I'm wanting to buy. One is the model 360 scandium, which is roughly the same gun but set up for 357Mag. I've borrowed one at the range once, and it isn't unpleasant to shoot, it is torture. The 360MP (the black alloy+titanium version) isn't hard to find in California. The other one I'd love to own is the 337-3 or 337-4 Ti "kit gun". It is the same as my 337, except in silver color (not painted black), and with a 3" barrel. It has never been on the roster, but was only made after the roster came into force, so they are exceedingly rare in California. Not that there are many in the other 49 states either.
