I'd happily snap up a duty size M&P in 10mm. Assuming it would tolerate a minimal diet of hot 10mm, it would be just fine for those of us living in bear and cougar country who could be in the city an hour later.

In fact, it leaves me wondering... a common course for those who want a 10mm but can't find what they want is to buy a base pistol similar to what they're looking for in 40 S&W and then use a finishing reamer to chamber it in 10mm.

So... I wonder if you could take an M&P in 40, ream it out to 10mm, and then find the necessary springs to adjust for 10mm loads. Hmmmmm....
