The mag was MADE for the 10/22 period and full stop! The Charger pistol was made to use existing 10/22 mags. The 25 rnd 10/22 mag predates the Charger pistol by decades.
MM, just wait until they ban all .22 mags over 10 rnds. That is the truth gun owners live with since Bill C-68, they will just make more and more laws and you will have your legal taxed goods stolen from you by the RCMP just like when you used to buy 30round anything mags and now with 25rnd .22 mags.
What needs to be done is to legally change the current system. The RCMP is a self-serving, self-interest group that is no different than asking the deer to make the deer hunting regulations. Only when the government sees the truth of this and agrees to the unfairness of it, will they change; but they will only change if they care...good luck with that one! Only a gun owners cares about guns and there are very few gun owners in office today.
