I love mentioning my new Sig Scorpion 1911!! But this time I have a real reason. My Sig came with 2 mags, Nice! I want one maybe 2 more. Now any real difference between the Sig factory or say Chip Mccormick or what not? The Scorpion has a mag well and needs a plate to go flush. I wonder if a flat plate can be pushed up into the well?
