Tanaka Sig Sauer P226 ... Alternative Cartridge?

Knowing how easily the 5mm 0-rings peel off the piston in Tanaka's standard cartridges, is there an alternative MGC, KSC, or other cartridge that can be used with little or no modification please

Thanks

Cerwyn,

I assume there was a conversion kit by Mulberryfield, to make firing Tanaka Sig with KSC/MGC 9mm CP-HW, the kit comes with det pin, recoil sp and 5 or 6 rounds, cost around 5-6,000JPY, but do not know if that is still available.

Regards,

K

Hello K,

Thank you for your help This particular gun belongs to a friend of mine and he's already discovered that the small 5mm 0-ring used in Tanaka's cartridge peels away from it's groove almost EVERY time it fires.

A cartridge using a 7mm cap, piston and 0-ring sounds a much better idea. KSC / MGC 9mm C.P.-HW should be perfect.
MulberryField would have supplied their 9mm Real Look cartridge I guess... would they be the Luger type
I'm certain he'll be interested in this conversion. If the kit is no longer available, can you advise why a different recoil spring is in the kit please
Cartridges and a Det. pin should be easy enough to find but a spring could prove more difficult if it's necessary.

Thank you again K,

Cerwyn, i had the mulberry field conversion kit and it never worked the rounds were to long for a start and the slide never went fully home, tried a few things with the kit and it was never succseful so went back to tanaka rounds even though the seal is a pain. never tried other 9mm rounds in though with an adjusted det oin so there may be something that will work but in my experiance not the conversion kit.

Thank you Claymore, that's worth knowing and will save spending good money needlessly

Another worry I've got is Tanaka's reputation from breaking easily... I understand that both 5mm and 7mm caps contain the same amount of "powder" BUT would a cartridge using a 7mm cap be too powerful for Tanaka's fragile model
The Mulberry conversion contains a new Recoil Spring... is that a stronger spring to handle stronger blowback
