H&k hk4

The model 4 was probably ahead of its time, with integration of polymer material and conversion barrels. I have one in .380 with a .22 conversion. Its weak point seems to be the plastic buffer that degrades over time so I preemptively replaced it.

It's a neat little plinker, very concealable but a bit on the heavy side compared to more modern mouse guns.

Agree with above. I believe I paid $500 as well back then, with original box, 2 barrels and 2 magazines for each barrel.

It was hard to find magazines for .22 when I was looking around 4 years ago. Never did add more.

Good price for a two barrel set. I've seen the complete two box sets go in the thousands. Learn about the buffers... ask questions.

The HK4 is not a polymer gun, other than the grips. That would come about with the P9/P9S which utilized a good amount of polymer in the frame. The frame of the HK4 is alloy.

It isn't clear from the listing what caliber barrel is included beyond the .22. .32 is listed and then the .380 is specified. If it is .380 I would probably pass. This gun really sings with .32/7.65 but is pretty doggone snappy with .380. I have owned them in both calibers. Some have also suggested that there is a limited lifespan of the gun in .380, buffer replaced or not.

That said, I would possibly go $500 for this gun simply because it has the spare .22 barrel. If the other barrel is .380 (9mm Kurz) I would begin a search for a .32/7.65 immediately.

HK's version of the Mauser HSC. Designed for 32 cal, and is iffy in 380. The aluminum frame with a worn or hard buffer won't take the shock. Here's one of mine.

I believe it had a .25 acp barrel available for it, as well.

Alex Seidel designed both the pre-war Mauser HSc and the post-war H&K HK4

I believe the H&K VP70 pre dated the P9s.

It certainly did featuring a truly polymer frame, not just one with polymer integrated into the construction.

I would again encourage the OP to acquire a .32 barrel for the gun , or even the .25 ACP barrel that has been mentioned. He should certainly avoid hotter .380 loads. In any circumstance it is essential to check the condition of the buffer and replace it is need be. Err on the side of replacing it. I have seen buffers in HK4 and P9S that were crumbling. Numrich currently has the buffers in stock. I believe that there may also be someone at the HKPro forum who is making buffers.

Great find and at a very nice price. Last one I saw was the 4 caliber set-up, in the box, for a little over $1K.

congrats


I regret not buying when had the chance.
