Title: +P+ ammo on a Scorpion?
Post by: Phyffe on May 06, 2021, 10:24:33 AM

OK, so don't judge - I took advantage of a friend with LE connections to help source some JHP ammo.

He turns around and says he got me a great deal on a few boxes of Magtech JHP ammo.

So I go - Sure, why not? At the price given me I thought I would be getting some of their Guardian Gold.

And then what arrives at my place are boxes of 115 grain +P+ JHPs.

I am assuming I don't want to run these on my pistols but am I right in assuming the Scorpions can run these easily? Anyone use +P+ ammo?

I haven't tested it yet by I have different hollow points in a few mags for home defense.

Kinda have same question also. But regarding the liberty defense rounds. Anyone try these yet thru scorpions? What I've seen YouTube is nasty. Gonna order some next month maybe in 9mm and 10. They have something like half weight rounds that get really fast. And can penetrate "stuff".. and still do alot to gel behind that stuff. If anyone has negative reviews on it I'd like to hear it tho prior to buying them.

CZ states that +P ammo is safe in CZ pistols but extensive use will cause the gun to wear faster than if standard ammo is used for the obvious reason.

As I understand it +P+ is not really anything definite- it sounds like it would be more powerful than +P; but some is and some isn't . . . 

Marketing hype or fair warning?

There is a SAAMI spec for 9mm Parabellum and 9mm+P, but there is not specification for +P+. With no standard for a percentage higher than +P means these could be only a little lighter than proof loads and earn that designation. YMMV

Per the Magtech website the velocities of their +P+ ammo looks very similar to their 9MM Nato ammo.

Can I assume Scorpions were built to handle 9MM Nato?

I’d never heard of +P+ ammo until a couple of weeks ago. I purchased a couple Arsenal Firearms Strike One pistols, they’re rated for +P+.

Magtech lists some data on their website but no pressures are given. These rounds do appear to be available here in the US as well. I would address any concerns with Magtech and CZ.

Definitely. In fact, that's probably what many agencies/departments in other parts of the world are running in their Scorps.

Not a fan of +P+ ammo.  As companies and nations can treat the designation differently and pressures can vary.  Remember one ammo tested +P+ where we were getting 1500 fps out of a Beretta 92.  Needless to say a steady diet of this would destroy the pistol.  +P designation have a more uniform pressure limit. 

The Scorpion was designed as a machine gun and around higher velocity ammo, so it would probably handle it in the short term.  Would not use it myself, just not worth the risk for a nominal gain in performance.  Putting even normal 9mm in a longer barrel will improve the velocity into the 357 mag category. 

Good luck on your decision.

+P is a SAMMI/CIP designation. +P+ is whatever the particular manufacturer says it is, so you have no idea what the pressure really is, other than what they put on the box.

So a pot luck then? ;D
