If range I always say whienchester white box or eagle or pmc all decent good brands .. I think whenchister is making a combo range and defensive pack too.
For carry/HD you will get a lot of answer but the common fav rounds are hornday critical defensive , sxtp or ranger whienchester , pdx1 is good , golden sabers are nice and sper is good . Buffol bore makes hot stuff .. Bascily most any name brand is going to be fine if you can try to get a low flash powder round I know pdx1 and CD are low flash the rest too I thik
All of 'em. Every one. If a gun like an M&P, Glock, SIG, or whatever would hang up on a specific make, that gun would be headed back.
These guns pride themselves on a well rounded diet.
I run WWB or AE at the range, HST (165, 180, doesn't matter), 180 Rangers, or 165 Gold Dots for carry. Eats 'em all.
Ahhh, the often asked question of which ammo to use. The answer is always the same, it depends.
Your M&P should feed, fire, and eject any of the major brands reliably. Everything else is a matter of what you want out of a round. I find the heavier weight bullets flip less and have more of a push when compared to their lighter counter parts.(ie. 180gr gold dot vs 155gr gold dot).
The heavier bullets typically get a little better penetration out of 3.5" and shorter barrels than the light weight bullets. The lighter weights typically get better expansion due to higher velocities. Of course these differences are small. We're talking, generally, 1"-2" differences in penetration and 50 thousandths of and inch in expansion.(.050)
For self defense purposes all the major brands design their newest stuff to meet about the same penetration and expansion with very little difference due to barrel length and even less difference for bullet weight. Buy a name brand that you like the looks of their bullet when expanded and try them out. When you find one that has a recoil you like and is affordable enough that you'll practice with it from time to time, stop looking you just found your carry load. Don't over think it. It's about having a quality round that YOU can be accurate and quick with.
For range ammo find one that has a recoil that feels the about the same as your carry load and is cheap.
As for range use, I always choose the cheapest that's available on the shelf (usually Tulammo, WWB, Rem, etc.).
For SD, again the cheapest available hollow points, after all, they'll all make a .355 hole in what they hit.
If you don't fight for what you want, don't cry for what you lost...
Sometimes you win, sometimes you learn...
It never gets easier, you just get stronger...
I have put more than 7000 rounds of reloaded brass ranging from Tula to Winchester through my M&P 40s. I have NEVER had a single problem with any of them. As far as self defense rounds go, I am partial to the 165gr. or 180gr. Black Hills hollow points. But, as others have mentioned above, the M&P will not be finicky with the ammo that you feed to it. It is made to be very willing to shoot what you provide. Enjoy your new gun!
165 on up.
Shoot the 155 for target, but keep HPs in the 165 and up
I would rather die with good men than hide with cowards

For the range, reloads. For defense I like Hornady Critical Duty
Ammo these days... your lucky if you can find it, even luckier if you get a choice.
My m&p loves the 165 Winchester fmj for practice critical defense for carry. But it's like a fat kid it'll eat anything you give it.
Walmart and Academy in my area have had lots of Winchester white box 100 rounds lately. Around $36/box. 165 grain has worked well in shorter barrel 40.
This one will give you the best 'proven' performance for 'Personal Protection' with no intermediate obstacles: Detail Page for Part # 23962
Also good is Hornady Critical Defense.
These are made with 'Fast-Burning/Low/Flash Powders' for a 'short 3-3.5 inch barrel.
There are others that 'may' work well for carry, but I wouldn't be the one testing them.

I normally shoot American Eagle 165gr FMJ or Winchester White Box 165gr at the range, Speer Gold Dot 165gr for SD. I also have Federal HST 180gr & Hornady Critical Duty 170gr SD ammo. I've experienced no problems with any of them.
