I just picked up the Senco SFN 40 nailer, In one word PERFECT.When I got home I pluged the gun into my air line took a two and half inch nail and sent it right into a piece of 3inch hard maple without any effort.I had a Bostich model 62 and it couldn't even put a 2 inch nail intothe same wood and it was more noisie and had more recoil, I tookthe gun back to where I bought it.Senco the only way to go!!!!!!!!!!!!
