I was a very active Silhouette shooter in the 1970s. I was also a writer and contributor to the National News latter. Served as state director for Wyoming.
This BS about Mdl. 29s being more likely to fail etc is just another load of nonsense. The Ruger BH had problems with ejector rods falling off and the new rod safeties blocks falling in to the actions. Dan Wesson were racked with barrel spacing problems. Actions binding was a Dan Wesson on going failure.
The real facts are the S&W was more expensive than the other guns. Shooters who could not afford good equipment was always findings something "Just as Good". Some things never change.
The very idea that dropping pinned barrels was an improvement is so ridiculous I won even reply.
