The L-frame came in at the tail end of service revolver, and I doubt many dept's ever carried it all that much, but IMHO it was the best of the breed.
I bought my first one, shortly after they came out. I was getting into NRA Hunter Silhouette, and bought a 6 inch blued 586. I also about the same time started shooting IPSC not having the money to buy a good 1911, I shot the revolver division with the L-Frame. As far as a basic stock .357 revolver goes it had no pier in competition.
The smaller K-frames had too much recoil, and the N-frame .357's have a higher bore axis and for me anyway have a harder kick. The L-frame was controllable And won a lot with it. But later I did go to the Smith and Wesson 25-2 in 45 ACP with full moon clips, because I could reload it a little quicker.
I had a customized 3 inch L-frame that was fantastic, and probably the smoothest revolver I ever had, and I carried it for CCW for a while but quickly found out that it really was too much weight and bulk for me pack, but it served as a pickup gun for several years.
I shot everyone's revolver back in those days, and I never had any use for the Colt Python or Trooper because the triggers were never as good as a Smith IMHO. And I can't remember a single shooter using one in IPSC, however If I had realized how stupid high they were to become, I would have started a retirement program by buying mint Pythons back in the 80's
