This message forum's search engine cannot handle the term "+P", so I have to post a new thread...

Can the M&P 9c handle the +P ammo? I'm looking at the Speer Gold Dot +P. Nothing in the owner's manual mentions +P other than for revolvers.

Thanks,

There shoudn't be any problem with plusP in the M&P9c. Like anything the harder you run it, the sooner it will wear out. So instead of being good for say, 50,000rds you might only get 46,000 out of it.

I suspect like most, I will shoot 99.9% range ammo, with Gold Dots in the mags for carry. And the occasional milk jugs full of water, for fun! ;)

Thanks,

You should be find with the +p ammo. I have shot about 200 rounds of my carry ammo that is +p+ with out a problem.
 
Pages 11-13 of the owners manual covers ammunition. You aren't supposed to use +P+ ammo at all and no +P in those specified revolvers. +P ammo, as recognized by SAAMI, falls into the catagory of ammunition your weapon is chambered for. Frankly, SAAMI +P is about the same as European CIL regular ammo.
 
This thread save me from asking, thanks:o.

I was wondering about +P+ in my Storm Lake barreled "9c" (converted from 40c). Obviously it wouldnt be a constant diet of such, but was still concerned enough to ask. We'll see how it goes.

I'm looking at those 127gr Ranger T +P+ as well.

Here's a link to a copy of the M&P Owner's Manual.

The pertinent text reads:

“Plus-P” (+P) ammunition generates pressures in excess of the pressures associated with standard ammunition. Such pressures may affect the wear characteristics or exceed the margin of safety built into some revolvers and could therefore be DANGEROUS. This ammunition should not be used in Smith & Wesson medium (K frame) revolvers manufactured prior to 1958. Such pre-1958 medium (K-frame) revolvers can be identified by the absence of a model number stamped inside the yoke cut of the frame (i.e., the area of the frame exposed when the cylinder is in the open position).

“Plus-P-Plus (+P+) ammunition must not be used in Smith & Wesson firearms. This marking on the ammunition designates that it exceeds established industry standards, but the designation does not represent defined pressure limits and therefore such ammunition may vary significantly as to the pressures generated.

By specifying which guns cannot use +P, I assume that means that non-specified guns can use +P. Especially since the specified guns are older revolvers, and this information is printed in a newer M&P owner's manual.

As for +P+, it seems to be saying that there is no inherent meaning to that designation, so who knows how overloaded it really is!

You're good to go with +P. I don't of anyone that's going to shoot a whole lot of it, simply due to the cost, but even if you did I doubt you'd break your gun.
 
Just follow the money. If you can afford enough +P+ ammo to put serious wear on your M&P, you can easily afford to buy 8 or 10 new guns.

A couple of hundred or couple of thousand hot rounds will not make any difference to the wear of your gun.
