I sympathize with those folks who have experienced problems with their RM07s (M&P Shields, M&P Bodyguards, lawnmowers, etc., etc., etc.) but for every one of those items that has been problematic there are hundreds (if not thousands) that have performed flawlessly.
I'm sure everyone agrees that in an ideal world no "out of spec" products would ever leave the manufacturing facility.
However, as adults we all know that the world we live in is far from ideal, in the secular realm and certainly much more so in the moral realm.
I've owned scores of S&W firearms and have had less than a handful that have ever had to be returned for service.
Years back my wife bought me a PC1911 as a gift. It had to go back to the factory for a sub-standard trigger.
A few months back I bought a new 4 1/4" M&P 9 C.O. R.E. It had to go back to the factory for a sub-standard trigger.
I then bought a new 4 1/4" M&P 40 PC Ported C.O.R.E. It had to go back to the factory for a sub-standard trigger.
I wanted a MRDS for a specific purpose and after spending many hours looking at them and researching features there was only one that I thought would fit my designs / needs - the Trijicon RM07.
I just put about five hundred rounds through my M&P 40 PC Ported C.O.R.E. with a RM07 this afternoon and it never missed a beat and is still as bright as when I first installed it.
It's something made by fallible mortals and it may fail the next time I use it. If it does I'll have it fixed and go on.
Take care
