leaves the tiniest hole imaginable. two things to get used to, if your used to using regular nailers, the safety is a double trigger, not a nozzle depression, so it’s easy to fire off, very easy. also there’s no rubber tip on the nozzle, so if you used to leaning into your nailer, you’ll leave a dent.
