The M&P (and descendant Model 10/64) is elegant in its simplicity. It is a revolver designed to function as a revolver should. it is basic and uncomplicated. Its form is its beauty. It is certainly in the top 2 or 3 of handgun designs when it comes to form and function.
Yes, every serious shooter should have at one. I have several (I'll only illustrate the model marked examples.)
A 5" 10-7 I bought new in 1979 and gave to my mother for protection in her home. Retail price was $133. I really didn't think it necessary but I fired 6 rounds through it to make sure it worked before giving it to her. It has not been fired since. It lived in her nightstand until she died on Christmas Day of 2011 and I brought it home along with the box of Federal +P 146 grain SWC HPs with 44 cartridges remaining in it.
I read a magazine story about 2" M10s with square butts and wanted one. I'm like that. Around 1998 I saw this 10-5 on Gunbroker offered by a pawn shop in CA (illegal to sell within the state because not approved as a safe gun by the state DoJ). Bagged it for the starting bid of $150. Ten years ago my wife had it engraved for my 50th birthday and added the ivory stocks. Gun letters as shipped in 1969 to a dealer very near to the where I bought it. Hadn't moved much in 29 years.
Maybe 12 years ago my wife asked me what I wanted for my birthday and I blurted out a 4" M10 in nickel. She got this c. 1979 10-7 off GB for $177 and I added the ivories a couple years late that I bought at the Tulsa show for $225. I hate it when the stocks cost more than the gun but I've done that several times.
A few years back I decided I needed a new "house gun." I immediately thought about a short M&P as nearly perfect. To make it even more practical I figured it should be a stainless M64. Again, my old friend Gunbroker produced this specimen that I picked up for $265. It's stamped for the San Antonio PD and I can't imagine a better working revolver. I hate the look of stainless, and it had some scratches from years of service so I polished it up bit after this photo was taken.
