As was asked need some more info. I am as much of a Ruger guy as the next on this forum but if you are limiting yourself to current production 9mm semi you are pretty much down to (LC9, SR9c, SR9) the LC9, which is pretty much a CCW, and not a range gun. Mine shoots great but its not a fun gun to shoot for extended range practice. The SR9c tries to be a CCW and a Range gun, many guys like them, its a compromise. Now, I don't have much experience with the SR9c. The SR9 is a full size pistol, it is a good range gun, I use mine frequently for steel challenge, it is also a good full size combat pistol. I have thousands of rounds through my SR9, have had to replace the firing pin spring retaining cup when it cracked and fell apart that was at about 6000 rds. That being said the current 9mm offering is pretty limited.
As much as I am in to Rugers, there are a lot of other potential options. with SA, SA/DA, Striker fired pistols.
The M&P series are some very good striker fired pistols and various options in 9mm with different barrel lengths and the pro series offering.
The other question are you only looking at domestic made in USA, or Pistols made or headquarters out side of the US. CZ makes some very nice 9mm.
Price point
if where it is made a consideration
what do you want to do with it. Range, CCW, competition
Good luck
Shoot straight and shoot often
