Love the P guns, 1911's are great guns but they don't do anything my P90 wont do. The only thing the P90 gives up to the 1911 is, IMO, the nostalgia factor.
But... I have to say that for me the SR9c has the best blend of size, accuracy, weight and firepower. If it proves to be 100% reliable like the P guns it will be my new favorite.
