dobe:
with LEO market at least 90% autoloaders, the questions about "hot" law enforcement loads for .357 are almost moot, although there are "hotter" commercial loads that are aimed at the hunting market. With many LEOs carrying 9s, concerns about the lack of stopping power in the .357 are humorous. Of course, the .41 mag was developed to give state troopers more power than the .357 offered without battering the guns of the time period. (it's now exclusevly a hunting round)
The article in question was in shooting times a few years back, I'll have to search my archives and still see if I have that issue. I think I've also read similar interviews in American Rifleman.
I've never had any problems with my Security Six.
I've went from the factory wood grips to pachymars to Hogue Monogrips, which I really like.
Another thing about the Security Six, at least in my hands it is as much of a "natural pointer" as the Colt SAAs, and much more of a natural pointer than my blackhawk or super blackhawk. Go figure.
The Security Six shoots where it points. Not so with the GP100, at least in my hands.
Is that important, well lets just say that it has impressed a few people, bouncing pop cans at 40 paces without aiming.......
And since it has been retired to "house gun" status, if I ever need it, I have confidence in it.
Back to the original topic - IMO, if it needs to be done with a .357 mag, you can do it with "standard" loads. If you need more, buy a bigger gun.
