I was wondering if a small diet of +p+ 127 grn winchester Ranger or Federal 9 BPLE 9mm 115gr be ok to shoot periodically in my Performance center shield? They would be leftovers from my Glock 19:)

I would encourage you to read the manual. It clearly states S&W position on +p+ ammo. You can then decide for yourself if you wish to run it.
 
You can, it won't hurt anything provided you don't use it as constant practice however you won't get much out of it due to the short barrel of the Shield. It would be a waste of money. You're better off with a good +P or standard pressure or even better short barrel pressure specifically for use in short barrel guns. It's made to expand reliably out of short barrel guns. It's harder to find but is out there. Otherwise standard pressure is fine


I'm not going to tell you not to read the manual but they have become a mix of fact and liability (cover your a..). For instance HK, despite being test proven for reliability with more than 30,000 high pressure +P cartridges and 6,000 proof loads without damage or excessive wear to any major components still tell you not to use them.

True and true. Two other points - any damage to your Shield (however unlikely) resulting from +P+ use will void your warranty, and there is no standard for +P+ pressure limits. Good luck in your decision.
 
As stated, manufacturers are in the habit of not saying that +P+ ammo is okay for their guns because there is no set standard for what +P+ means (unlike with +P and non +P). If someone wanted to just load ammo up with double charges that will grenade your gun and they call it +P+, technically, they aren't wrong.

That being said, Federal and Winchester are a little more reasonable than that.

Personally, I don't see the need. If you really want more energy than +P, get a longer barrel or a .40 or .357sig.
 
The last couple of times I've asked different folks at S&W (as an armorer), they told me they'd check and call back. I was later told by both that while +P is okay, they don't recommend the use of +P+ in the Shield 9.

I've not yet heard of the same restriction given to LE agencies using the M&P 9 or 9c, though.

There's a lot of good quality standard and +P loads offered by the major American ammo makers, so it ought to be easy to find something to use.
 
Thanks for the input guys, ill refrain from using it. like others have said, plenty of great +P Stuff to meet the requirements.
 
Trade in the 9 for a 40 and run standard pressure rounds.

Um, what? My H&K manual says this:
NOTE: In compliance with NIJ Standard—0112.00,
currently there are no known ammunition types that
meet the general guidelines set forth in this section
that are not compatible with the USP 9mm, USP .40,
or USP .45 pistols. All USP pistols are approved for
use with +P and +P+ ammunition.
The use of +P and
+P+ ammunition does accelerate wear and reduce
the service life on the component parts of any pistol,
including the HK USP.

Conversely, the S&W manual says this:
"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.
 
The P series guns do say that since it accelerates wear, +P and +P+ is not recommended. However, it appears to stop short of saying don't use it.
 
however you won't get much out of it due to the short barrel of the Shield. It would be a waste of money.

Winchester 9mm 127 gr +P+ clocks 1206 avg out of my Glock 26.

In addition, Massad Ayoob states that round is his favorite load for a Glock 26. It's been proven in numerous Law Enforcement shootings.

That being said, I had an opportunity to discuss this round with a Winchester L.E. Ammo factory rep. He stated he's only comfortable shooting it out of Glocks & Springfield XD's.

I friend of mine purchased a 9mm Shield and asked to borrow enough of my +P+ for his magazine. The first round popped the white insert out of the front sight. That being said, he stated the recoil was manageable.

If he's comfortable shooting them in XD then there ok with most everything else. I'm surprised he didn't mention HK USP since those things will digest over pressures all day long

The white insert is a known issue with the Shield. Probably nothing to do with the ammo being fired.
