I have had 2 framing nailers, a porter cable which I lost in the shop fire and a Rigid which was the replacement. Both are excelent tools. As near as I can find out the advantage to cliped head nails is that they can get more nails in a strip. This might be important to a framer, but I always opt for the round head because even home projects can require a permit and inspection. My experience is that inspecters are really hair spliters particularrly with people who do thier own work rather than hire a contractor. It would be just my luck to have some hair spliter tell me I have to replace every nail in my new 50×100 barn because I used cliped nails instead of round. I would be more concerned wit the differant lengths of nail the gun will take. Some things just don’t need 3” nails but some do. rt
