Check your area for in door pistol ranges at gun shops. They will rent pistol for you to try and will be more than helpful in finding the right one for you.
Pennsylania is a big place. I'm sure there are ranges around that will rent, perhaps not close to where you live, but how far are you willing to travel to keep from buying the "wrong" gun.i have done alot of research..... still don't know, i need to get a 'feel'. where i use to live, in NJ, you can rent guns at the range, where i live now, PA, there doesn't seem to be any place to rent 'firearms', so i don't want to buy a gun on a 'crapshoot'.
I agree I have a sub compact .40 and a service 9mm. These are really easy to use, very reliable, and readily available.Take a look at the Springfield XD-9 or XD-40.
