    +P+ ammo and M&P

    Is the M&P line of firearms able to handle +P+ ammo?

    from the manual (a good source of information about guns in question)

    “Plus-P-Plus (+P+) ammunition must not be used in Smith &
    Wesson firearms."

    Thanks for the quick reply ...

    I am thinking about buying a M&P 40 and wanted to see if +P+ ammo is okay to use.

    There is no +p or +P+ in .40 caliber.

    You are correct. I would just add that I just recently looked at the SAAMI website. They only list +P for 9mm and .38. They don't show +P+ in any caliber. It can mean anything the ammo company wants it to mean. It could make a loud bang, or a really loud bang, or maybe something really, really loud--perhaps louder than you might want.

    There is no reason to use +P+ in .40

    No such thing.

    As for using +P+ 9mm in the M&P, as was previously stated, the manual specifically says do not do this. But the reason they make this statement is because there is no SAAMI specification for +P+ 9mm loads. So there are no pressure standards by which the loads can be gauged. You could most likely use a +P+ load, such as the Winchester Ranger RA9TA (127gr +P+), if you wanted but were something to happen the gun or you, you would have no legal recourse since S&W covered themselves with their statement regarding such loads. S&W is protecting themselves by making those statements in their manuals against the use of +P+ ammunition.

    FWIW, the above mentioned load by Winchester generates 42,000 psi which is quite high for a 9mm load. As I recall, NATO specs call for pressures of 38,500 psi.

    There are some excellent 9mm loads in standard and +P from which you could easily find something that works for you. Take a look at Gold Dot 124gr +P (53617) and Federal's HST offerings for starters.

    Hey guys, thanks for all of the replies .... As it turns out, I meant M&P 9. However, since I first posted this question I have now decide to go with a .40s&w. Either the M&P 40c, Glock 22 ... Or maybe Glock 23.

    If you are willing to go to a G22 but still like the M&P, skip the M&P 40c and get the standard M&P 40. You'll be happier. Then install an Apex USB (Ultimate Safety Block) to completely remove the gritty trigger.

    I'm not so sure about that. I like my .40c alot better than my full sized .40. Also I don't find the stock trigger that bad. In fact I never noticed it until a few people started whining about it. Even then I didn't find neither one of the triggers to be that bad. Especially not bad enough to drop money to "upgrade" something that didn't need it IMO.

    Anything can be improved upon. I have three M&P's and have installed the Apex USB in all of them. M&P's are famous for having gritty/sandy triggers (in their pre-travel) out of the box. It's easy to see why when you field strip and examine them. The Apex USB completely eliminates this and returns a nice trigger. Both my M&P 9 Pro Series and my M&P 40 come in at under five pounds (the Pro averages 4 pounds 12 ounces).

    DITTO Have had a 40c for two years. Never a problem, feels great in my hand, and the trigger is just fine.

    EDIT: To the OP, the only M&P I use +P in is the 340. Much nicer on the hands than a .357.

    The several triggers I tried seemed ok to me, and better than the XDm. I can't see putting in $100 of new trigger parts into a $500 gun that I will use mostly for self-defense. Certainly for that purpose, the stock trigger is fine.

    I know one guy who is just so picky it isn't even funny when it comes to little stuff like that. I am pretty dang accurate and have the tightest grouping I have ever had out of any of my other pistols with the M&P. One thing I would recommend is putting about 500 roudns through it to break it in. Alot of people said after 400-600 rounds the trigger started feeling alot better.

    I guess it really is just personal preference. To me it has one of the nicest triggers I have ever felt. But that is for my feel.
