Heizer Defense PK 045!

They had a two shot .223 version at the local shop a while back. They couldn't sell it so they gave it away in the monthly raffle.

Word was it was NOT fun to shoot.
 
there are videos of the PK 045 being shot and it doesn't appear the .45 ACP is giving the shooter any major issues.

He fires a few rounds at 1:40. Going by the sound/report, kick, and big puffs of black smoke I'd almost be willing to bet those were weak target loads.
 
Yes, but if you notice the barrel is not at the top of the slide like most other semi autos. Looks like the recoil spring may be above the barrel. Recoil may not be as bad as one would think.
 
I think the idea is neat and lets be fair there has not been a ton of firearm innovation lately so anything novel is worth a look IMO.

However the first time I saw a video of this firearm the thing that struck me is the method for disassembly. A single locking block and the slide comes the rear of the gun.

If I remember correctly the initial designs of what ultimately became the 1911 had a very similar setup that was corrected so a malfunction would not send a sold chunk of steel at your head.

I might be wrong here and the gun may have been changed since I watched that video several months ago, but if not I think this would concern me as an owner.
 
I want it and I'll learn how to shoot it. There isn't anything I can't learn how to shoot. About the only thing I really don't ever want to shoot are the few examples out there of 50BMG pistols.
 
Any ideas how this thing works in .45 with a fixed barrel? Simple blowback like the HighPoint with a very heavy slide and strong spring?

Also, I couldn't find the other dimensions apart from the width anywhere on the net...

IMHO you've guessed correctly.

Based on watching the Gunblast video on YouTube, the pistol does not appear to incorporate a locking mechanism. The Heizer staff boasts about its small number of moving parts, so I don't believe there's any sort of hidden locking block, gas piston, or separate breechblock.

The pistol's operating system appears to be a scaled-up version of the Smith & Wesson 422/622/2213/2206, albeit with a takedown pin that improves on those pistols' field-stripping procedure. (Taking apart the Smiths requires wedging a shell casing between the slide and recoil spring guide to allow the recoil spring retainer to be withdrawn. The Heizer takedown pin simply releases the tension and the recoil spring is removed forwards, as there is no massive barrel "overlug" on the Heizer to block it from coming out.)

About as ugly too.

When I first saw it, I thought of an overgrown and overdecorated S&W Model 2213... ironic, considering that I now realize that's basically what it is!

Of course, IMHO the M2213 isn't exactly a beauty queen either.
 
I had an AMT .45 Backup years ago. Mine was reliable with FMJ and pretty easy to shoot. The construction did reflect the times and it was heavy for its size though.

This might be the logical evolution of that nifty little gun.

I seriously doubt they would make a .45 this small in straight blowback configuration.

How much does it cost?

I think this is a very cool looking pistol. If the price point is right ($500.00 or less) I'd love to give one a try when they come out with a 9mm version. But, if the capacity stays the same as the .45 version then I'd just get the .45. The only thing that concerns me is the design of the grip safety, seems like it would be too easy to accidentally disable it when holstering or putting it in your pocket if that's how you would carry. I would think with a pocket holster, if you holster first then put it in your pocket it would be sufficiently safe so probably no big deal.
