I have the 9c... 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.
Actually the number is 4000 rounds, and at least 50 are +P. Like someone else said, I don't think that is all I would shoot through it, but so far it has been fine.
A bad day at the range is better then a good day on the job!
The P stands for pressure. There are industry standards (SAAMI) for the pressure generated in various cartridges. The +P indicates cartridges loaded to higher pressure and thus higher velocity than "standard". Most modern guns will tolerate +P ammo just fine and it is quite popular for use in SD weapons.
I believe the SR9c is one of the top carry guns of all time. It is that nice!
For Home defense, range, and carry the SR9 full size is excellent also, just depends on what size gun you wish to carry. All I know is that they are very impressive guns, dependable, accurate, nice trigger, large magazines.
What more could you want?
