I received a M&P today that I bought on GB. Closed auction now, still viewable, #1006655580 if anyone cares to look. Really nice condition with nearly 100% case on hammer and trigger. Matching serial numbers S 922362 on the gun, so 46-47? I would have thought it would have magnas but does not. The right grip has a number lightly scrawled in pencil that I cannot quite make out but MIGHT be matching. The grips fit very well so would they be original or long ago replacements for magnas? Thanks for any enlightenment.
