I am new to this forum but appreciate the info on 9mm. Question: Is the 9mm x 18 Makarov suitable for regular 9mm weapons? I know it's Russian but I am unsure about using it in my 9mm Ruger SR9, Sig P250, Springfield XDm 9, or my Glock 26. Can you expand on the great info provided previously. I look forward to learning from all those who post here.
