The P250 was Sigs attempt at launching a new "have it your way" gun platform. As a Sig collector I was turned off immediately. If I "want it my way" I'll go to Burger King. Sig makes exceptional weapons...modular change out parts aren't required IMHO. The Sigpro's on the other hand got an undeserved bad rap...they are excellent shooters and a real value in today's market!
