If SAAMI created a .380 +P spec, then it would be acceptable to fire ammo that meets that spec.

Buffalo Bore ought to call this ammo +P+ since it is loaded beyond any set pressure SAAMI limit. +P always has a pressure limit. I wish +P was copyrighted so SAAMI could tell people not to use it when it isn't correct -
it's false advertising. There are only four +P ammo specs - 9mm +P, .45 ACP +P, .38 Special +P and .38 Super (which is the +P version of .38 ACP). There is no +P spec for .40, .380, .32, .45 Colt, etc.

There are loads that are common and well above any SAAMI spec, like .45 Super, but those loads have their own non-SAAMI definition, and the Walther manuals say to stick to SAAMI. If you call Buffalo Bore as the Walther manual suggests, Buffalo Bore will tell you their .380 +P is not loaded to a SAAMI spec.

Personally, you couldn't pay me to fire overpressure +P+ ammo in a gun with a cast zinc slide (PK380). Don't do it.

SAAMI; 9mm is 330 ft/lbs., .38 Special is 170 ft/lbs., .380 is 215 ft/lbs., .380 Buffalo Bore +P (not on SAAMI, off of BB site) is 294 ft/lbs .

The PK380 is a steel slide, not a cast zinc slide. The P22 has a cast zinc slide.

Howdy y'all.
Thank you to all who took the time to post replies. It is eventually up to me to decide to shoot/don't shoot, but the opinions are a valuable resource. I have not shot it yet with the Cor-Bon, mainly due to it being rare and such a small box.
I may decide to use it for the zombie attack, if it ever happens.
And my apologies to Mr. UberAlles (etc.). I was not criticizing your post, I was simply interested in the PK380 and the so-called +P ammo. Plus I was wrong anyhow; I have now gone up to nine 9mm handguns.

It's all good Moonburn.

I shoot/EDC 230 grain .45auto, even with Walther +P approval, I avoid it.

Sig Elite V-Crown chronos at 830 fps/352 ft-lbs (summer carry), Win Defender PDX1 chronos at 920 fps/432 ft-lbs (winter carry) thru the 4.25 polygonal barrel Q45. Really like these 2, both have shown single digit standard deviation.

I have 200 rds of +P+/super velocity in 38 Special, got it with a like new Charter Arms Undercover from my FIL (was my MILs purse gun). I'm willing to bet 200 +P+/SV thru that little 38 would kill it!

I will chrono the two guns soon (but that means after I get back home for leave on Christmas).

I tested approximately two feet from the opening of the chronograph. Here are the, mean average velocity, numbers I produced:
Federal HST -- Most felt recoil
99 grain Hollow point, stated velocity 1030 f/s
Tested 985 f/s
Winchester (white box from Walmart)
95 grain FMJ Flat Point target ammunition, stated velocity 955 f/s
Tested 849 f/s
Magtech (From Midway)
95 grain FMJ, Stated velocity 951 f/s
Tested 856 f/s
Inceptor -- Least felt recoil
56 grain ARX, Stated velocity 1315 f/s
Tested 1260 f/s
Please keep us informed as to what results you get when you take the PK380 out and test the velocity through it.

Today I made it out to the range, with my chronograph. My main purpose was to check my hand-loads. I ran them over the chronograph using both my PK380 and my Kimber Micro .380.

Because I wasn't focused on comparing factory ammo I just used one factory load for a baseline. I then compared that to my hand-loads.

Here I post the standard disclaimers: don't treat my numbers as anything you should use. After all, I just might be a total idiot, you have no way of knowing. Don't exceed anything in tested reloading manuals.

I used 3 grains of tite group with both of the bullet types that I loaded. 100gr FMJ flat point, and 90gr XTP hollow points. I am only listing the mean averages. I did notice that I had less Standard Deviation with the XTP than even the factory loads. The FMJ loads had more SD than the factory ammo.


Magtech (From Midway)
95 grain FMJ, Stated velocity 951 f/s
Tested:
PK380 953
Kimber 854

Reloaded
100gr FMJ flat point
PK380 964
Kimber 943

Reloaded
90gr XTP
PK380 993
Kimber 933

As you can see, using the factory loads, there is a considerable gain from the extra barrel length in the PK380. However, the fast burning Tite Group isn't gaining as much from the longer barrel. Again, be aware that these loads are close to max. I am not as bothered by that as some may be.

What follows is pure opinion: The factory .380 loads are a bit light because they need to be safe in blow-back pistols. Further, those pistols are of wildly varying age and quality. My .380 ammunition is only used in pistols that have a locking breech design. As such, I am comfortable shooting the max loads listed in the reloading manual. However, I do not exceed those numbers. I suspect that, if there were such a thing as .380 +p, these would be close to them. So, what am I saying. Simply, don't go beyond the loads in the book, but I feel comfortable with any load that is in the book.

For chronograph data comparison:
I get 862 fps from my Beretta Pico 380 acp (2.7" barrel) with an 102 grain lead cast bullet for 168 ft-lbs of energy.

Aguila 95 grain clock at 877 fps from that pistol (Beretta Pico).

So the PK380's 3.66" barrel makes about a difference of 100 fps gain.

But on the other hand the Pico is a true mouse pistol for EDC while the PK380 is kind of an full size pistol not able to CC.
Pico is 5.1" long x 4" high x 0.75" wide.
PK380 is considerably bigger not being anymore an pocket pistol with it's 6.5" Long x 5.2" high x 1.2" wide.

The PK380 is more or less an home pistol and the ideal weight with it's 22 oz for the 380 acp caliber. Most 9x19 in 22 oz plastic pistols are not that pleasant to shoot and are snappy. For 9mm Luger one wants an 34 oz gun as the Beretta 92 is and not an 22 oz gun. 22 oz weight is fine for 380 acp however although I am not uncomforted with the 11.5 oz of the Pico but for extended shooting like 20 rounds in a row my hand goes red and starts to "feel" something.

In my opinion, the PK380 is far away from being a full size pistol. It`s a compact pistol with great ergonomics and is easy to use. The accuracy on shot distances is ok, for what it is and what it costs.

In terms of CC, I think it`s a good size for CC. Not to small that you can`t get a good grip and to to large to be bulky.

+1 for what Ken said. This person likes to talk Beretta and what a full size gun the PK380 is, well I have a PX4 Storm compact that is my EDC(larger than PK380) and it does just fine with CC. I don't think the person owns a PK380 either based on their other posts.
