There are rubber basepads available for the tanfoglio mags. I bought mine from Brant Shooting Sports (site sponsor) Whether they are legal for production in IPSC is debatable, but I don't think that Canadian RO's are making an issue of them at this time. I have installed them on my tanfoglio mags but have not shot any matches with them yet.
I use both the normal tanfo. mags and the chrome ones - no difference except price & I like the looks of the chrome ones. I also have the rubber butt base pads and would recommend them as they definitely help cushion the drop on concrete. As Maurice stated-no issues using the rubber base pads in IPSC production.
