I have tried just about every tupperware compact out there and feel that the M&P edges them all out (for me). It shoots like a full size, has good capacity, reliable, durable, and easy to conceal. What more do you need?

Me too - but as others have said OP needs to run the drill for himself. Good deal on the SIG (never cared for them myself though) - it's just so much personal preference.
