Why no modern top break revolvers?

[MCgunner]

The locking area in the frame of that Izhmash looks very small to handle the pressures of a .357. Top breaks usually don't loosen up all at once, but over time. It might work OK for a while (500 rds? 1000 rds?), but IMHO it will shoot loose pretty quickly.

Yeah, Jim, that's what I was thinkin'. I think I'd stick with swing out cylinders or my Blackhawk for that sort of pressure. Nothing wrong with a SP101 for a powerful carry piece. If five ain't enough, I'm dead anyway.
