+P+

[Short Bus]

Does anyone use +P+ in a MK9? I use Federal HST 115GR +P+ in my Glocks and would like to use it in the Kahr.

I don't think Federal HST ammo is +P+, where did you get that idea? There is no reason that your Kahr won't shoot Federal HST factory ammo.

No major bullet manufacturer that I know of makes or sells +P+ ammo. I could be wrong but it will have to be proved to me.

I was wrong, the +P+ I have are Gold Dot

I also have some of these Federals https://www.ammunitiondepot.com/499-federal-9mm-115-grain-p-hi-shok-hp.html

How many gun manufactures have you found that will say their gun will handle +P+ ammo? I think they would be opening their company up for giant lawsuits from people injuring their self and blowing up their guns. Post a list of these gun manufactures names if you know of any.

No manufacturer recommends +P+ that I know of, but Glocks handle them without issue and Beretta PX4s really like them.

I am asking here because people here may have real world experience using +P+ in these guns, I know it's not recommended because there's no SAMI specs for +P+

I did bookmark your ammo supplier. The prices look very good.

I like that they sell 50 round LE boxes also.

My personal choice for self defense ammo is to never go over maximum loads. I am a reloader and when I load to book maximum on my loads they are plenty snappy for my tastes. I never load +P loads and +P+ is definitely out of the question for any of my guns. Safety is my first priority. I have never felt the need for excessive pressure ammo. Too many things can go wrong. Max loads will always get the job at hand done.

I like the added velocity to ensure the hollow point expands.

I've ran 50 rds. or so of Federal BPLE 115gr. +P+ through my CW9 without issue. They really didn't feel any hotter than HST 124gr +P.

No, but my Glock G27, with a Storm Lake 40-9mm conversion barrel, has eaten box after box.
My MK40 is an all stainless steel tank.
Feel that a limited dose of +P+ 9mm wouldn't be a problem for an all steel MK9.
But the real question is why?
New high tech ammo performs really well from a short barrel.
Federal HST or Winchester Ranger T-Series in 147 gr standard pressure is what I run in all my 9mm guns.
Soft shooting and very accurate.
You may want to reconsider.

My Kahr MK40 was running Speer GDHP Short Barrel (only comes in 180 gr sub-sonic standard pressure).
But later switched to Federal HST 180 gr.

Recommend you check LuckyGunner Labs for quality short barrel 9mm performance.

I like HST 135 gr. In .40 (good luck finding it), but I am currently clearing out my .40s and switching to 9mm.

Light 40 S&W (High Velocity & Energy) tend to under-penetrate.
Velocity and Energy isn't the whole story.
FBI Protocol isn't an exact science.
But it's the best we have to compare ammo performance.
Things have changed...

Again, recommend you look at LuckyGunner Labs data.
