Tokyo Marui 1911 magazine

[Fat_P]

Hello, I do not know if I'm spas in the right place to put is thread. If not, I'm sorry,

I have a Tokyo Marui 1911 and I have a problem with my mags. I have trouble to make 8 bb with a load of gas. I do not think this is normal.

I tried to twice the gas. And the same.

Continue like to put the same gas when the mag tells me it is full. And also without success.

I do not know what to do or if it is really a problem of seal. Thank you

[redzaku]

don't worry, the tank in it is small, you'd be lucky to get 12 shots off

[Fat_P]

This is very disappointing same. Paid too much and not be able to drawn the full capacity of the magazine.

@ redzaku, have you ever used a TM product before? they are extremely gas efficient in stock form.

Stock TM 1911 will get more than 30 shots off on a single fill.


What kind of gas are you using?
Do you have access to more than 1 mag? (try different mags, if the problem persists you will know its something within itself)
Are you using a - near - empty can of gas? (this one has gotten me more than once, resulted in something very similar to what you are describing)
Is it in stock form?

Never before.

But I know this is really execellent as products.

I use King Arms Green Gas and Propane.

odd, i used both TM and KJ and got about the same amounts of shot capacities in both TM and KJ 1911 and then again, one had a metal slide and the other had a polymer slide

[GBBR]

I can confirm hattrick's statement, my KJW gets minimum 20 shots before it starts to "cool down" and / or run out of gas

Try the following

- hold magazine upside down, inject with duster ( TM is NOT supposed to use green gas / propane ) inject gas for 15 seconds, seriously, count to 15....

- manually press the magazine upward, worn mag catches = poor gas transfer, = poor effienceny seals that are in bad health = poor effienceny

then post results.


BTW!!!! if you leave you ANY gas blow backs cocked for a long period of time springs will compress and weaken, also, try using WE magazines, although WE has a bad rep, I prefer WE mags over TM mags as they can hold much more gas

Man you don't know frustrated i got troubleshooting a build one night and all my mags did this because of an almost empty can, it has enough gas to give 2 good shots or lockbacks and then nothing!

Guys, stop with the disinformation. With a plastic slide, TM 1911 mags can shoot over 30 BBs easy on propane and when my 1911a1 was brand new, I'd get 42 shots on duster.

Also, WE 1911 magazines will NOT fit a TM 1911 and they do NOT hold more gas. Actually, whatever brand of pistol you have, if they fit TM magazines, you will always get better performances. Even if its just the slide catch working better or getting slightly less cooldown when firing rapidly.

Fat_P: if this happens with all your mags, the problem might not be with the magazines themselves. Maybe your loading nozzle is cracked, the piston head o-ring is damaged or has dried, there is a problem with the floating valve in the loading nozzle that lets too much gas escape reducing efficiency.

Also, what weight of BBs are you using? If you are using .30g and more, you will get fewer shots on a 1911 because they use slightly more gas and the mags do not hold much gas to start with. Heavy BBs weight will not reduce your shots count so low, but it is something that is good to know (ie. this is not the problem you are trying to fix, just extra info I'm putting here).

Ok, I'll watch with my other mags Tokyo. I generally use the .25 g or .28 g BB BASTARD. I loaded yesterday in real cap and I take 8 shots and the last I ran out of gas and I was at .20 G. if the problem is not the mags you know a good gun tech could check me?

[Drakker]

I don't know of any guntech that advertise themselves as good with GBB around Montréal. But since we are both going to Long_Bong's game on September 7 I'd be happy to look at it there. I am pretty familiar with the 1911/Hi-Capa platform, I can probably find what's your problem before/after the game.

[ILLusion]

If you're willing to sh ip, I can look at it for you. It's definitely not normal to get only 8 shots, or even 20 shots with a stock Tokyo Marui 1911. You should be able to easily get over 30 shots on a single fill of gas.

Gee this guy seems to know what he's talking about....


@drakker you would need to use 3.5g (non-existent) bb's to add enough weight to reduce your maximum shot count by 5. Never mind the 25 round loss he is having.

@GBBR In regards to what you mentioned about the hammer spring tension, though 100% -TRUE- IMO this is not the problem.

If his hammer spring was weakened he'd get more shots off, not less. On the other end of that spectrum he would get a dead, drop, click. (as i call them) where the spring doesn't have enough tension to release the valve.

Before you do anything, get a fresh can of gas.

If that doesn't work I'd look into drakkers OTHER idea regarding the condition of your floating valve.
Though i've never had a TM floater break...ksc on the other hand :P

If you read my original post, I did say it was not the problem he was trying to fix.

But, I did some tests 2 or 3 years ago with my TM 1911a1 with different BB weights, you do get fewer shots with 0.30g BBs, my shot count went from around 30 to around 25. This was back when the only upgrades I put in were a Tanio Koba Twist barrel and a Firefly extra soft bucking.

It might be due to the way the twist barrel works, but I think the low gas capacity of the mags is to blame. The heavier BBs spend more time in the barrel, keeping the floating valve open slightly longer. You would never notice the decrease on a larger magazine like a Hi-Capa mag, but on the TM 1911 the difference is there.

[hattrick]

Re-reading your original post I do see that.

However I've gone from .2 to .4 with no change in round count using a TB barrel on an otherwise stock 1911. This makes me think the TK barrel might have been to blame for that. Since as you said it works differently from regular inner barrels.

I've never tested a TK barrel properly so i cannot comment for sure in that regard.
