I just was given a nail gun by a friend, he replaced it because it was giving him problems and he could not figure it out. It started to shoot 2 nails at a time and also it was give him trouble with bending the nails.

Personally to me it sounds like a bad batch of nails, any ideas on what to check for?

Double Kiss
Many woodworkers have the problem of firing two nails when they pull the trigger a single time. This is called a Double Kiss. A double kiss is extremely dangerous since the second nail can strike the head of the first, and ricochet back and hit the user. It is also very bad for the driver and piston, as the second nail can impact the head of the first and the impact can jam the driver shaft and even bend it.
The actual cause for double kissing is when the pressure-foot safety of the nailer is first released, and then reapplied. That is, the nailer will bounce off of the wood far enough for the safety to disengage, and as the nailer again makes contact with the wood, the safety is re-engaged; and a second nail will be ejected. So the actual cause is due to the bounce of the safety.
While the most obvious cause is that the user is not applying enough pressure to the nailer to keep the head on the surface, this is compounded when the air pressure to the nailer is too low. The low pressure will make the nailer bounce much more. (If you don't believe this, turn the pressure way down to say 20 PSI and shoot a nail. The nail will only penetrate the wood a little bit, but the nailer will lift away from the wood by a lot., no matter how hard you hold it down

Its a Porter Cable, I dont know what gauge nails it takes and such yet, I need to research the model number. My buddy is a framer though so I would guess he was using the right size nail, but who knows, he said he didnt have time to mess around with it and just bought a new gun.

Download the manual and check the specs.
