Is there any difference between the 15ga and 16ga nails/nailers?

I have a 16ga nailer and I sometimes get a nail that will turn or pile up in a wad and mess up the trim. The 15 ga usually drives a nail with a point. The 16ga drives a T head brad with a blunt end. The blunt end will not split boards as easily as a pointed nail. Since I don’t own a 15 ga nailer I am not sure if you can get blunt end nails for it but I have a friend that owns one and I used pointed nails when I used his. To get an angled magazine you have to get the 15 ga nailer. I think they both have a place and we often use them interchangeably.
You are correct the supply of nailers is endless. If I were buying today I would get one that has a service center in my area and something I could buy nails for locally. Sometimes you have to be careful buying on the internet because you can’t get the tool serviced in your half of the nation.

Thanks for the info and insight. I will have to go back and look at the nailers and nails more carefully.
At this point, I am leaning towards a 15ga unit because of the angled magazine and the pointed nails. The only other thing I want is that the tool be oil less. I know they make them. I will just have to see how much they are and hopefully when I am ready to buy/need it, there is a sale going on somewhere.

There is usually a sale….somewhere. You just have to find it. Get on the internet and look around. I have a gun that needs to be oiled. I have not had any problems with it leaving stains so far. I have had it for ….12 years I believe. The oil blows out with the air discharge in the top. I am not against oil less guns I am just saying I haven’t had a problem with that. I buy some tools from CPO. they are tools that someone has had a problem with and returned. These folks repair them and sell them. I think I get a better tool in many cases.
