People have asked Armscor directly about the M200 series revolvers. "Not +P rated" might be a bit of an overstatement, but Armscor's own correspondence has always been that their design and metallurgy is insufficient for a steady diet of +P. They won't blow up. They will shoot loose or break.
In terms of ruggedness, I wouldn't consider that promising.
Here is a thread on that subject at Armscor's own forums with feedback from Armscor and forum Admins: http://armscor.proboards.com/index.c...ay&thread=1110
