Query: Bostitch HP118K Pin Nailer

I was not able to make it sink one pin in any material. Those little pins hurt when you run your finger over them! Maybe I got a bad one. It is in the shop now being checked. My partner has a Grex and has had no trouble at all. I went with the Bostitch because I have had great service from their other products. If you buy this gun and have trouble, send it back before the return deadline.
