MD Charlton please get this right. This would be a deciding factor in buying this "pistol" or not.
If Sig Sauer manufactures a magazine that is designed for BOTH a pistol AND a semi-automatic rifle, then I would expect the RCMP lab to rule that they all have to be pinned to 5 rounds. If an after-market company designed a magazine for JUST the pistol, then I would expect that one to be allowed to be 10 rounds.
