Is everything else a browning action?

ETA I put this in here b/c of the arguable improvement of function w/ suppressors.

Blowback pistols; like PPK, Markorav, Beretta Cheetah, etc.

Yeah, quite a few, HK p7, p9s, Desert Eagle...

The P7 is an odd one: the barrel is fixed so it should work without a Neilson device. accuracy is supposed to be excellent.

What makes it odd is it can handle the hottest 9mm ammo. It does this by having a "delayed" blow back by using a port in the barrel and a piston delay device.

It also has that weird HK routing in the chamber; allegedly its possible to remove the extractor and the gun still fires/cycles just fine.

Lot of innovation in that gun.

The new Walther CCP also uses this gas-delayed action (w/ a fixed barrel).

hadn't heard of this one...


someone imbed this shit! brilliant! Make double stack service pistol w/ threaded muzzle please!
https://www.youtube.com/watch?feature=player_embedded&v=zd6yiyYm63o

well, in the mean time i doubt there will be any threaded barrels availible for this, whatever the barrel really is in this gun, its not like something you can just remove and replace...

better video perhaps:

Ha ha, that could be used on a rifle, funny, use a gas piston not in place of blowback action, but to delay blow back action.

was aware of the hk p7 & p9, P9 being roller locker delayed, both being fixies. was aware of desert eagle fixe gasser, and of various blowback 380 or < pistols. I shoud have specified 9mm.

AR15/9mm pistol
SP-89 and clones
MAC pistols
Uzi pistols
Tec-9
Hi-Point pistols

And FWIW, the Beretta 92 still has a moving barrel. It just moves fore and aft, engaging a tilting locking block vs. a tilting barrel. It can still only handle so much weight hanging on the end of it before causing a malfunction.

by pistol i meant like the conventional definition or a normal handgun pistol (e.g. 1911, Glock etc), not what is called pistol b/c of our legal distinciont b/t pistol, rifle, SBR etc.

The hi-point, fixed barrel?? Its a blow back even in 45??

I am aware that the 92 is not a fixed barrel, but it seems tha for aft movement is easier than pivoting w/ a suppressor. I woul use a booster on a 92.

The Beretta PX4 series has a rotating barrel on the non-subcompact versions.

Though, if you are going to put other stuff on it, it might not work so well.

CZ52 uses roller locks.

Steyr GB uses gas delay.

Arsenal Firearms Strike One has a non tilting barrel. It moves like a Beretta 92.

So is the highpoint just a basic blowback??

Yes, the torkerev pistol

Very interesting. Same principle as the new walther but uses the outside of the barrel as a piston and a large bushing, if you will, as a cylinder which when pressurized holds the barel and breech together.

Ahh yes, the one that looks sorta like a glock w a picatinny rail from russia.

Hey, how anout the steyer..you kmow that newer one for the last 10 yrs or so. Is it M9.? Is it a browning action or more like the beretta?

Also, there was some, i think checq, pistol that STI was importing for a while that used a roto locking barrel like a beretta 8000/stoeger cougar and the px4 storm.

Yep, bloback, fixed barrel pinned to the frame.


Inspite of the action, a guns merica blog said it is softest recoiling 99 he ever fired.

Bad dope on the p7. It Does NOT handle 147 well, and the HK armorer's manual does not recommend it. Shoot 124 or less.
Link Posted: 1/17/2015 9:57:01 AM EST
HK P9 is a 9mm roller delayed also.
So is the oddball Wolf Ultramatic

Blowbacks might be fixed barrel but a lot of sound escapes through the unlocked chamber

Walther P38 is also a 9mm non-tilt barrel pistol. (You may recall "The Man From U.N.C.L.E." had suppressed P38s at times).

That is a single stack right? Are they any new ones, perhaps double stack ones or are they all old surplus units?

Yes, the P38 is an 8 rnd, single stack mag pistol.
I don't make any claims at being a firearms expert and, while I do have a P38, I do not have a Beretta 92 for comparison but it is my understanding that the Beretta 92 action evolved from the P38 design. As such, the Beretta 92 or equivalent, would likely be the double stack version of a modern P38. As for newer P38s, I believe the P1 is an alloy frame version of the P38, and some but not all parts interchange.

Best of luck.
