I finally had the time to get to the range and put 100 rounds through my new Heizer PKO 45. The factory says that these gun require a 200 round break in period so I am only 50% through that period.

My initial impression when holding this gun was it was not terribly heavy and the controls are intuitive, although it felt totally different then any other firearm I have shot. The large mag release button is a plus.

One of there spokespeople said firing the pistol is like shooting a .22. I totally disagree. The recoil impulse was more similar to a .38 spl +P out of my SS S&W 649. After the 100 rounds I did have a bit of a hot spot on the web of my hand just below the joint where my index finger meets my palm. Surprisingly the gun was not a beast to shoot and was relatively comfortable. I once had a Micro Desert Eagle .380 and this puts it to shame , that gun was beast to hold on to.

Accuracy was about what I expected. I could easily achieve approximently 2.5" - 3" groups at 7 yards. The sights are very good. Consisting of red and green fiber optic pipes. Follow up shoots were easy to make and quick to acquire. Point of aim and point of impact were very close together and I had no problem making repeatable shots.

I did have several malfunctions. I had 3 light primer strikes on S&B 230 gr ball, and a couple failures to feed. The primers were seated farther in then I usually see and that may have been an ammo isse. I had 2 failure to feeds and no light primer strikes on Remington 230 gr ball. Sometimes using the slide release the PKO would not strip off a round from these super tight magazines, racking the slide eliminated this issue. All ammo that was loaded back into the pistol fired without a hitch. The slide always locked to the rear on empty.

The grip ergonomics, I think could be better but were not terrible at all. Even with the short grip and flush magazine I could get almost get my pinky on the frame. The gun feels very solid and a high level of finishing went into this pistol.

Stay tuned to Part 2 and Part 3 once the factory break in period is achieved.

The overall fit and finish of the gun was very impressive with a lot of very tight tolerances. It may be worthwhile to note this is like the easiest pistol to field strip, it took me like 10 seconds with no practice and like 12 seconds to put it back together. It is such a plus.

It is very odd but I like odd pistols. It seems also pretty well built and finished but I don't see many room for this gun in the market.
I mean, what this pistol does that a Kahr CM45 can't do?

Having rented a CM45 before. This is considerably thinner and easier for at least for me to shoot. Felt recoil was less noticeable and seemed more controllable with less twist. I also found the slide easier to rack. PKO45 mitigates muzzle flip to a much higher degree. CM45 is pretty impressive.

I really thought this gun was smaller , surprised by the size (using your hand as perspective). Sounds like it's working out alright for you. I'll be watching to see how it breaks in and how it functions long term for you. I consider these specialty guns and as such it will likely show ammo preferences (I would suspect), I would find a loading that it likes and stick to it. What ammo do you plan to carry in this one? I like gold dot 230 grain short barrel for my sub 5" barreled 45s, less flash and a hollow point cavity that's designed to work better at lower velocity.
Good luck.
 
Interesting gun. Hopefully the function issues will iron themselves out once the break in is done.

Thanks for sharing.

I am with you bro, I thought the gun was smaller despite all the photos I came across. There is a comparison pic on the internet with a Officers model 1911. Its essentially the same length and height, but way thinner. It makes sense when you put it a light jacket's pocket, it doesn't really print like a gun. I too consider this a specialty gun, I strongly doubt I will carry it. I have to admit I love the space pistol look, it would make a great candidate for some stupid cerakote.I have this thing about carrying semi-autos. I absolutely need the fire arm to go bang when the trigger is pulled and I feel a revolver is better suited, that is simply my opinion. If I were in the future more comfortable carrying it I would probably go for the 118 gr polycase ARX, I hear that the Gold Dot is some really good stuff. I honestly wouldn't have any problem carrying regular 230 gr ball.
