I searched the forums and couldn't find anything about it. I use my M&P as a carry weapon for now (I would love to get into competition shooting, I just don't know where to begin to look in my state of Minnesota.) I only use the +P rounds when I'm carrying. When I'm at the range, it's 115 gr Winchester white box all day. My question is will the Winchester PDX1 124 gr JHP +P be fine in my weapon? As in no serious damage, blown out barrel or things of that nature?. I don't want my EDC to fail when I need it the most lol.



Thanks for all the help!

Manual says +p are safe, and many/most police departments issue them.



PDX-1 is what the FBI is currently using, I hear dependability is an issue with them too.



You might want to look to DocGKR for help with selecting your Service Pistol Duty and Self-Defense Loads.

Thank you so much for these links! Are they both primarily pistol or do they vary?

I am not too sure about this. The last time I looked at any S&W M&P manual, all of them warned about using P+ or +P+ or any non-compliant SAMMI ammo.

I have also written to S&W and they were very clear about it: DO NOT USE it.

The M&Ps by design are fully supported and capable of firing +P+. I suspect for product liability purpoes S & W, just like any other Mfgr will not advocate anything referencing +P+ or maximum SAMMI.



My limited experience of about 6000 rounds in my M&P FS40 proves to me the handgun capable of functioning at minimal and maximum power factors without stressing the shooter or the M&P. FYI: Over 95% of the ammo were reloads.



Shootem up!

Never heard of P+ before, I emailed S&W about it and they said the exact opposite, they said as long as the ammo is SAMMI compliant, which the +P

is you can use it.

You obviously have not kept up with your reading. S&W manuals are readily available on the S&W web site if any of you wish to know the truth.

I am sure of my post and fail to appreciate your implication. I would never risk the safety of any one of our members by guessing/fabricating something like this... PDX1 124 gr JHP +P will be just fine in his M&P pistol.



Edit: Toned it down a bit.

Guys:



My earlier reference to +p or +p+ loads was only in reference to the 9mm. There is not a +P that I am aware of for the 40 S&W.



My point still stands, an OEM Mfgr will be conservative and likely recommend against using any extreme hi power loads due to their product liability exposure.

Just me, but +P and +P+ seem to be more bragging rights and extra wear than anything else, although I guess it would help a 9mm a little....



My vote is to practice with "standard" loads, and run a few of the nasty ones, if you feel the need, through, just to get the feel of them, and to test function.



(IMHO, in the winter, when dealing with heavy clothing, the +P rounds might actually be useful. +P+ probably is still a bad idea....)



It always gets my attention when somebody buys a new gun and is immediately looking for sights, grips, and hot loads.... Not to disparage the OP, but it's always best to shoot the thing "stock" for a while.



(There is one exception, besides the winter clothes things. Some SD loads just don't like short barrels all that much, and you may be better off to find some loads that were designed for that. There really is a significant velocity drop, below what's really a good idea to depend on....)



Opinionated-R-Us, I guess....

For your convenience, here's what the latest manual says:

Quote:
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.


Use of “Plus-P” ammunition may result in the need for more

frequent service.

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

and could be DANGEROUS.


For those who disagree, guys, I am just a messenger. I did not make up the rules here.

Sure, there may be a lesser risk with +P but they are clear about premature wear and tear. Now, why would you want to do that to your M&P?



Again, I have direct confirmation from S&W and that was only a few months ago. I am pretty darn sure the manual has not changed and the products have not changed yet to accommdate +P ammo.



Also, I am not trying to argue here, guys. This is a fact, IMHO, that I am presenting and I am not pulling it out from somewhere just to scare people. Do as you wish. I have no intention to displease anyone here. Let's be calm about this.
