I have both and the Shield is definitely thinner and a little lighter than the SR9c. You give up 3 rounds for the thinner pistol. The Shield with the 8 round mag a little more concealable and comfortable than the SR9c with the finger extension. The SR9c takes a 17 round mag as well as the 10 but it is not nearly as concealable. Both shoot very well and I have had no malfunctions with either. My wife also has the SR9c so they would likely be our shft handguns for their sharing capability.
