I have a Pardini. 22 pistol i use for Standard and Bull's eye shooting. The gun is great, but the magazine is the pits. The Plastic/rubber base at the bottom of the magazine is very thin where the strakes of the metal shell tube slips into the base and the thin rubber breaks, making the magazine useless. Does anybody know how to fix the bottom part or can I purchase just that bottom section and not the whole magazine?
