How to suppress a HK P7M8?

OnyxSkyDV · Post by **OnyxSkyDV** » Mon Nov 27, 2006 11:02 am

My wife has a P7M8 that she would love to suppress.

It seems like with the fixed barrel it would be perfect, yet I have no idea how you get an extended threaded barrel, or get it installed onto the pistol.

Anyone have any ideas they can clue me in with, or some links they can send me?

Thanks!

We silenced P7M8 and M13's for the military several years ago. We made the barrels and silencers. HK installed the barrels in the weapons. We still have several barrels in stock.

Please save me at least one barrel!

That's great news. PM sent.

Now I gotta figure out how to get a barrel installed in a P7M8...

I have no personal experience with a suppressed P7, but I have heard numerous times that the P7 is not a very good suppressor platform... something about being gas retarded... not very quiet, and a lot of blow back.

I heard that also. But I shot the AAC Navy 9mm can on a P7 and I was satisfied.

I would have thought that the fixed barrel aspect of the P7 would have made it ideal for suppression, I am interested to hear otherwise.

If the P7 is not a good candidate for suppression, what other pistols, 9mm or larger, are considered the best choices? (Shooting for "movie quiet" or as close to as possible)

I suppose I should mention that I am looking for a quiet Dry can, not a wet one, though one that can be shot wet on occasion would be nice.

Thanks for the info, I find this very interesting.

I swapped the barrel on my P7 PSP and it was reasonably easy to do. I made three jigs/fixtures to help support the frame and allow the barrel to be pushed out as well as the new barrel pushed in. We used a big press at the local technical college for the actual swap.

The can is my own creation built on a 30mm unidirectional carbon fibre tube. It is 6.7" long and weighs a scant 130g (4.6oz). It is pretty good dry - certainly hearing safe. It is is very VERY quiet wet.

Very sexy looking can. Very... "Hollywood."

Is it threaded, glued, or both?

What are the theads on the barrel and what can was used? How much for the barel?

Thanks,
Chris

Once you learn the wife can count toys in the garage you buy a gun safe. Now I need a new gunsafe and an airplane hanger.

No thread, just glue ...... or more properly epoxy, which is a lot stronger than "glue".

I don't expect this can would survive a ton of abuse like a fully metal can would but it is strong enough for normal shooting rates. I have already put a couple of mags through it with no problems.

The thread is 1/2" x 28 and the barrel came from AAC. The can is my own design.

Hey I call polymer 'plastic.'

While the carbon tube is high on the cool factor it actually isn't much lighter than the equivalent aluminum tube. It has quite a thick wall for strength but which ultimately adds to the weight.

I am in the process of making a version to fit a short recoil pistol to see if the extreme light weight of this can will allow it to cycle without a booster.

I found this pic but don't know who threaded it or made the extended bbl. Anyone know?

I think this is the same gun but better pics

This is my factory, polygonal threaded barrel for the PSP. I shoot it
often. It's one of my favorite suppressed pistols to shoot. Not the
most "silent", but to my ears very pleasant. It's also wickedly accurate
suppressed.

I am thinking of selling it but really want to trade for a locking slide
Beretta from Knight's if someone knows of one?

Found this thread on a search.

Does anyone know who makes tall sights for a PSP?

Would they be needed (all ready tall enough)?

Here's an ad for a P7M8 threaded barrel over at HKPro:

Haha..That's me! Although I want that in my PSP. I have decided to go with an Hk barrel from AAC. It'll be all Hk part. Just thinking ahead if I don't like the project.

As for the sight issue I asked above. From talking to Rsilvers, a can in the line of sight isn't to big of an issue with 2 eyes open. After all you don't focus on the target, its the front sight. I have never shot a gun with a can covering the target but I'd imagine I can get it to an acceptable level of accuracy.

I like super heros that endorse P7's.

My can is 30mm which is just slightly smaller than the standard 1.25" OD tube. My PSP sights are not obscured by the suppressor.
