I purchased the Power Shot Heavy Duty Brad Nails in the largest size that would fit our Power Shot combo staple & nail gun which were the 9/16" of an inch size.
I have never used any sort of nail gun and was very excited by the prospect of nailing things up with a simple squeeze of the Power Shot handle. Ironically, the hardest part was getting the staple/nail gun loaded with the nails! After finally figuring out how change the setting on the stape/nail gun, I began to load the nails and found the strip of nails broke apart very easily and it was near impossible to load the gun with single nails.
After getting the gun loaded, I attemtped to hang a cardboard backed print on a wall. The nail shot through the cardboard, but barely even knicked the wall! I made sure the gun was set on the most powerful setting and tried again with the same results. I found this quite annoying as when I use the staple part of the gun, the staples are dislodged so fast and hard they sink into whatever I am stapling on the wall.
I gave up, but later my husband purchased a different brand of nails for the staple/nail gun and these ones had a pointy tip (whereas the Power Shot nails had blunt tips) and they worked wonderfully. Maybe these just weren't the right kind of nails for what I was doing, but they were the kind recommended by the manufacturer, which is good, because I won't recommend them ;).
