I am a Smith fan from way back, having been given my first one as a 13 yr old. I do not feel a comparison can be made from an oeiginal Model 19 to a current 2 pc barrel, key hile thingy they make today. Not the same, never will be.
However, given the current crop of wheelguns available to the public, I fell Smith is still the best, and really the only, option. Colt, the only true competition that Smith ever had is no longe in the wheelgun business. Taurus tries, and tries hard, but they just cant get there. They have some awesom ideas, and some cool concepts, but the results of these rarely pan out. Rossi...oh, never mind.
Ahhh, now we come to Ruger. In my opinion, Ruger was once on its way to eing the peer of Smith. When the Redhawk came out, and the Security and Speed Six were in production, they were on the fast track. With the introduction of the heavy, ugly, and unergonomic GP/SP series, they dropped the ball. The Six series guns had decent triggeres, and great handling attributes.The GP is a joke, IMO. I also believe the rumored strength discrepancy between the two makes is mosty rumor, with a tiny bit of fact thrown in, with all of it being remedied by the L-frame introduction.
In the end, there are a few "good" revolvers left, but for the real deal, there is only one choice, S&W, old or new.
