We don't use coil nailers in Australia for framing .The coil nailers I'm talking about is the AN611. We use them mainly for nailing off bracing ply, cladding , decking and nailing off straps and tie downs. The older of the guns would be 8 or 9 years old and is only recently showing signs of wear. I bought a senco about a year ago but rarely use it as I like the Makitas better.
