extended hi cap .22 magazine?

[2fast4u]

for my markIII target? do they make any higher cap mags then the 10 rounders?
i don't care if they are 15 rounds or 30 i just would like a bigger one for playing around at the range

I've never seen nor heard of one.

A long time ago, Ram-Line made a 12-round metal bodied magazine or a 14-round polymer magazine for the MKII.

Those are the only two that I'm aware of for the MK series pistols.

It would be cool of someone made an extended mag like the 30 rounders you see for the p-series 9mm's....

A 30 rounder magazine for a RIMMED cartridge is harder to get to work than any cartridge that is RIMLESS such as the 9mm.
