Framing nailer is a rough gun it’s made for high impact framing for rough millwork and specially made by design to get into tight corners and to toenail with high impact velocity so you really the finished product on the framing nailer is less than desirable again the siding nailer, on the contrary, is made to go upright
if you notice it’s lighter and weight and most importantly it’s got an adjustable trigger that adjusts the depth of the nail getting shot into the siding so you can have a uniform shot in siding over and over and over again.
