I have been confused about the cocking lever on the p7 for quite some time.

Exactly what does it do and how?

Squeeze to set up the striker. It locks to the rear and is held back ready for release and the spring sends it forward onto the primer. I assume the 77B is striker fired too.

The 1911 has also been given the treatment...

DAR, it's your thread, so tell them how the GB system is somewhat different. I know the answer, but you go ahead.
 
The Steyr GB is a gas brake system. There are 2 gas ports located halfway down the barrel. The barrel just before the gas ports has 3 gas sealing rings. The gas is bled off behind the bullet and fills the void inside the slide. The bushing on the end of the barrel serves as a gas plug. The pressure prevents the side from recoiling backwards until it drops to a safe level (after the bullet has left the barrel) and then the slide can cycle. It is a ridiculously simple system and results in a pistol with very few parts (someting like 30 less parts than a Beretta 92F). My GB with the comp has logged over 80k rounds with NO jams of any kind. Never had a hiccup either. Like all gas retarded pistols using lead bullets can lead to a kaboom as the gas ports get clogged and can lead to dangerous pressures. Always use jacketed rounds inside a P7, M77B and Steyr GB.

Not mine. :( The 77B is a bit ugly, but (hypothetically) it would make a nice platform for a suppressed version due to its fixed barrel. This 1911 would probably be a single shot if it wasn't a gas gun. You see, the heavy can weight can prevent the barrel tilting on a stock 1911. This is all academic, of course.

The GB was also produced in FA. That would have been interesting.

This, I presume is a recent mod to prevent the cocker from coming back and taking out the trigger finger as that other thread suggested. I actually feel better about it.

Thanks for the pix. I believe you are the first poster ever to post the real goods. We do need targets and groupings though.

I'll try to post pictures of groupings in the next little while. Going to try to take it to the range again on Thursday and drag the digital camera along. The way that the trigger guard cocker is made it is very very unlikely that the slide can drag it back and with the blocker there, there is no chance of losing a finger.

Being gas operated does have its academic benefits...

A FA GB would be interesting. Would be a beast to control for those 18 rounds though! Your arms would start straight and end up fully bent with its recoil. Would be easy to stay on the target, esp. with the comp! The comp is very effective and dual purpose. There is a threaded insert in the end, with the insert in it is a full comp and with it out it becomes a flash suppresor that
reduces ALL flash from stiff loads. Very neat design.
 
I think that 77B is butt ugly, but I really like that Steyr GB :) I have to admit this is the first time I heard about them :redface: are they still being made?

EDIT; never mind, I just did little research...

I wonder how fast the gun heats up after rapid firing... anyone know? Wouldn't that be one of the reasons for the trigger guard design? When the gun gets too hot the user doesn't have to burn his fingers on the slide?
 
lol, instead of having a soldier who got one of his arms blown off to leave the battle field, the Commies say: Comrade! You can still shoot with the other hand! Charge!!!! lol
 
I noticed that the sights are sort of greenish...are they 'glow-in-the-dark' (tritium, or other material)? Are these sort of sights common on other Norinco pistols?

i *think its just a green paint, other norcs i've seen like the Sig clones have a yellowish white painted dot
 
I met someone at the range with one. It is terribly hard to #### with your trigger finger. It is almost hopeless. But I think if it is cocked, then insert mag, then use cocker it is easier. But pull (I'm guessing) goes from about 30 pounds, to about 20.

Mine has some crappy green paint in the sights. I will be replacing that with white paint.

I ran through an entire mag of dummy rounds today with the trigger cocker (just to see if I could). The last 2 were really tough to do but it can be done. I agree that the pull is around 20lb as it needs to compress the recoil spring and the spring around the gas chamber. I have also been working the last 6 years with my hands and have quite strong forearms which helps a lot. I think the trigger cocker is mostly there as an alternative to press cocking to check for a chambered round. I could not see 5'4" Chinese soldiers using this feature very often... It is a nice pistol and the trigger guard cocking is just a nice added touch.
