I did some research on these nails. It appears that they just make fasteners for other brand nail guns. What is the concern of using them if they fit your gun? http://www.magnumfasteners.com/pstrip.html
well I have had problems with sub standard nails .I'd rather spend the extra money than buy new guns.I looked them up also.I did pop a strip and they worked fine. I had just never heard of magnums.So far so good though.
