Just Ordered!!

Just ordered the Tanio Koba GM-7 Tactical Short model. It just came out at the beginning of November!

Lucky for me, my girlfriend is Japanese and has a friend there to ship it to so she then can ship it to me in the States!

Cant wait to get this one!! My girlfriend told me from reading, that there were only 100 made, not sure if thats true, but I did read that he makes certian productions in limited numbers.

These are probably the most reliable modelguns when it comes to firing, you should be happy without much troubleshooting :-) Limited series too, they are only made in short batches. Depending on model it is up to a few hundred.

Thats what I hear...they are very reliable! Im glad I got my other model working proprly now, with the execption of a few jams from trying to fire too quickly...double tap method...lol!

But I am hoping the first impression of this model will be a good one. How do these aluminum open carts work?

TK cartidges are originally plastic. They work in the simplest way - just a shell and a cap inside, facing a detonator pin in the barrel. O-ring is on the detonator pin instead of piston/o-ring combination in the cartridge.

Aluminum cartridges are an after-market conversion done by BWC company, I don't think you find them standard in TK models.

As smootik says, the Alumnium cartridges are aftermarket parts. There's an upgraded extractor too which may be required if firing them.

There is a whole frame insert that needs (?) replacing:

Actually, this model comes with the aluminum carts, so I guess the frame, and extractor are already upgraded...I had to find one that came with this stuff...all other sites I looked at had the gun solo.

Tanio Koba sells cartridges separately from model itself, as they are plentiful and cheap. That's probably why you weren't able to find a set with cartridges.

I am still not 100% sure if frame part and extractor are required, or just recommended:

The one I ordered was a set...it stated the carts came with it and that was confirmed with an email my girlfriend sent to the company...and they said that I could order extra if needed. So we'll see...I think Im addicted now...if this model turns out ok...lol!

Tattoojew,

I used to own TK GM-7, this is certainly one of best model for firing.

As to the metal rounds, it is not original rounds cames with a gun.
If you want to use those metal rounds, you need to replace an inner chassis with steel ejector.
It seems you have contact to get those, but if you need any help, drop me a mail anytime.

P.S. yes, it is 100 limited model.

Well if this particular modelgun is coming with these aluminum carts, wouldnt all that be upgraded already?
