I swear I'm a broken record when it comes to the 9mm question.
Taurus PT-92 in stainless. This is by no means a very concealable gun but for fun plinking it'll do great. It dose have a large grip so take the old lady down to the gun shop. Way under $500 sometimes under $400 shop around.
For the quality of the gun and price no other suggestion is gonna touch it. Trust me
And on another note I'm still looking for complaints about the gun. Malfunctions only, no fit and finish crap. If it goes boom...its good.
