Can a new malfunctioning gun be returned?

[Charles]

I have been shooting for 3 years. Still feels pretty new to me. I own a Glock 17 and an M&P shield. They both worked flawlessly out of the box. Just purchased another 9 mm handgun from a different manufacturer. The weapon fails to return to battery and fails to feed frequently. I have tried three different types of ammunition. I have cleaned the gun twice. It feels like the wrong choice for a concealed option. Just have no confidence that it will run more than one magazine without a failure. I asked the salesman if they would exchange the weapon and they said they could not. I asked what the return policy was and they said they don’t have one. they said once guns are fired they cannot be returned.

Not sure if it matters, but I live in Nevada. The weapon ran me about $500.

I returned the weapon to the manufacturer for warranty work and expect to receive it back in about a month. Upon return, if the weapon still proves to be unreliable, what are my options?

Can defective guns be returned? Are they all purchased on faith alone?
