I'm reminded of when Ruger introduced their SP101:
- first it was chambered in .38 Special +P,
- later, it was approved for some .357 Magnum loads, but, not all of them,
- later still, it was authorized for any .357 Magnum ammunition.
Maybe that was evolving R&D, or maybe it was a marketing ploy?
Some guys, bought all three increasingly powerful versions of the SP101 as they became available.
Not for collecting purposes, but, because many customers wanted an unrestricted .357 in a small frame revolver.
Maybe Ruger will continue to upgrade the GP100 in the same fashion?
Or maybe I should just buy the mid-sized, 5-shot, S&W model 69 in .44 Magnum?
Since everyone "knows" that a S&W is more stout than a similar sized Ruger . . . Right?
