Is the only difference between the two the size?
Can the 9c really take +P if so can the sr9? May be a stupid question but I can't seem to find information anywhere on the Internet and my local gun store isn't the smartest. The girl I dealt with didn't even know how to check to see if it was loaded
I have shot both and myself I prefer the sr9c. Yes it can handle +p. I've had mine for over a year and it functions perfect with over 2K rounds fired. I only shoot stand velocity rounds out of mine and on rare occasions shoot +p, but it handles it well.
I have the 9c and it has had no problem with +P. I looked at a Walther PPQ to replace it and decided not to. Have 400 rounds through it and most of the issues have been the cheap range ammo. All but one round have fired when re-loaded into the magazine and gun. I have never had a problem with self defense ammo, and have about 100 rounds of a couple different manufactures fired through the gun.
I have both in stainless. The SR9 and the SR9c are excellent guns with mild recoil and they are very accurate. The SR9c with the 10rd mag is very easy to conceal. It and the PT145 are my main EDC guns. For target shooting, I like the SR9 a bit better because it feels more balanced in my hand.
