When I first saw the Milwaukee M12 3/8” Crown Stapler (2447-21) at the manufacturer’s yearly New Product Symposium media event in June of 2017, it immediately became one of the tools I was most looking forward to using.  It’s not the first non-manual stapler to exist, nor the first cordless version to exist, but nevertheless I thought it would be a worthwhile addition to the sub-compact M12 line of tools upon first inspection.
