Older S&W revolver.
Power, superior workmanship and beauty. All in one package.
I agree 100%. When I began my search for a revolver for Service Pistol Class, PPC, I knew that a 4.2" barrel on one of these older S & Ws was going to be a bit of a unicorn hunt; even 5" are a bit of rare bird. I also noted that the Ruger GP100 was held in high regard by many shooters, so, I would wait for either a S & W or a GP100; what ever came along first. A new in the box, 4.2" GP100 came along at a great price, and I grabbed it. I have either close to, or just over 1000 rounds with it. All have been home-loads that are very mild, firing 158 gr. lead SWCs. I have yet to fire a full pressure .357 in it. I will at some point, but right now my goal is to get as good as I can for a discipline that I love. The GP100 had a good trigger right out of the box, but after shooting it a bit and dry firing, it is super smooth.
Negatives:
Well, I can't reload as fast yet with speed loaders as I can with mags. Part of the issue is me needing more practice, the other part is the Hogue rubber grips that most come with, not giving enough room to align speed loaders easily. I have a set of the smaller rubber ones, with the Rose Wood inlays coming. Others claim these are better for speed-loaders.
Not really a negative, but the tolerances are tight on this pistol, so if a primer is not quite fully seated, it will bind and lock up the gun. Now that I know this, I clean all of the primer holes, and I pre-inspect my ammo much more closely. My 9 mm, my .40 and my 1911 .45 don't seem to care.
I am pretty good with semi-autos, but I have already noticed that in double action, I can out shoot my groups with the semi autos (which are also minimally loaded).
A good, solid, heavy gun that runs smooth, that will shoot .38 special might be a great starter; reloading costs are similar to 9mm if reloading light, target loads.
Despite the few negatives, I find myself really liking that revolver more and more, and having less desire to shoot my other pistols at this time. The one below is not mine, but it is identical to mine.
