+p Ammo

So the MP 45 says it can handle +P ammo. Does it?
Reason is.... I also have a SR45 that claims it can handle +P ammo and ended up sending the gun back to Ruger for repairs after 100 rounds.
Anyone shooting +P on their MP's?

Running +P in .45ACP (assuming 230gr) isn't that common is it? In 9mm, a common defensive load might be 124gr +P, but that's a different animal.

What jasonuscg posted from the manual pretty much says it all though.

Well... the +P I received was duty ammo from Minneapolis SWAT buddy. So Ya you're right... it is uncommon.

Interesting. What brand/bullet design are these rounds?

Ive put about 40 rounds of +P through my 45c with bo problems yet. Im aware that thats not a large enough number to say if it can or cant handle it but i trust and believe in the M&P. I had a SR40 and i just believe the m&p is a better built pistol

How about +P out of a 9mm Sheild? I just picked one up and had the same question.

The Shield can handle 9mm +P as a defensive round, but not as a steady diet (every day range fodder).

Have you browsed the manual? It covers it... Somewhere between Pgs 11-13 (iirc).

No I didn't look at the manual yet, i was being lazy. I thought i read it was good for it but one of my buddies from work disagreed. I'll look at the manual and point it out to him.

I am unsure why anyone really uses +P ammo for anything. If you want "more power" than a 9mm then get a .40S&W. And 45 ACP+P makes very little sense to me as well. The 45 ACP is a well established round without the extra pressure and even the FMJ loads have a good service record.

Just my humble opinion.

I just wanted a little extra in a short barrel of the shield while keeping the extra round capacity. I carry regular pressure stuff in my full-size, but +P in my compact, so i was wondering if the Shield could take it too.

Hornady Critical Defense is designed to expand better from a short barrel. I carry it in my Shield. The non +P version of the load.

I'm interested in 45 +P for black bear. Particularly the Buffalo Bore 255 gr hard cast lead flat nose.

I'm wondering if the pistol will handle it--not much just enough to see where it shoots and of course kill off the legion of black bears that are going to attack me. They've been getting a little too cozy 'round here lately.

If that doesn't pan out I've always got the .44 Super Blackhawk.

Thanks

I use Underwood Ammo hard cast 255gr FP .45acp +P for deer hunting in the swamp down here, and my Colt Combat Elite 1911 handles it fine.

I'd think an M&P would do fine as well when using it as a bear load. It's not like you going to be shooting a lot of bears day in and day out.

Kinda what I figure.
Plan A is bear spray.
Plan B is the .45.
After you've got him all pissed off with the pepper spray, and he keeps comin', you kinda want to deter him with, um, predjudice.

UNLV? What year?
I was graduated in '96 but was a non-traditional, IOW old guy.
History major.
