Question which of the nail guns are any good?
I had the old blue 6-in-1 framing nailer. It was good for the price (I got it for under $60), but got jammed a bunch. I had to turn it upside-down with no nails in it, and drip oil on the hammer directly to get it to run reliably.
It looks like that model was replaced with a red/silver one.
The palm nailer was pretty good, but I ended up buying a PC, because of the option to use different tips (otherwise the HF one was just fine by me).
I've got an 18 gauge nailer/stapler (I believe Item # 97524).
Well worth the $20 I paid for it, to be used as a stapler. As with the other HF nailers I've used, the depth control just doesn't work as well as on my PC nailers, and since the hammer is as wide as a staple, the impression left behind from a countersunk brad nail is also as wide as a staple. If I'm using brad nails, I'm using them to be inconspicuous, and with this machine, I'm left with a lot of putty work to make up for the wide dimples.
So, PASS on staples. FAIL on brad nails. Stick with a dedicated brad nailer for that.
My pin nailer is PC. I wasn't going to buy the HF one, because it has no safety on the trigger. The PC safety trigger is really cheezy plastic, but it's better than not having anything at all.
I've had good luck with their 16 gauge finishing and 18 gauge brad nails and staples.
I haven't tried their pin nails, and I'm a little scared to, because I know that one bad pin can trash the hammer because the parts in there are so fine.
