I am not positive but don't think so..the one article I read stated the basically built the gun around the magazine as they wanted to have at least 10 rounds in a compact...the one thing I wish it did do however is accept magazines from the other Sigs like a Glock..if its a 9mm you can switch between the model 17,19,23,etc...but, I get it..cant have it all... and having a concealable compact holding 10 or 12 rounds..that is pretty cool..carrying an extra mag or two..quite a bit of firepower on a sub-compact..
