I currently use a Duofast wide crown electric stapler. I decided to try the air stapler from Harbor freight. Even though it also says it's a wide crown stapler up to 1/2 inch it only fits 3/8 inch crown staples. My question, is it ok to use 3/8 inch crown staples when recovering? One of the main reasons i'm trying the air gun is that the Duofast is hard to fit in tight spots sometimes, like the side pockets.
