mine takes 15 gauge LNT (LAMAR NAIL TECH) nails. I have two DeWALT nailers .... but the 18Volt one thakes those. My 14.4V angle nailer takes 16 Gauge .... can be a little confuddling.

BTW I became a convert to the DW product after building several Floats for the Myer Christmas parade a few years back. The Paslodes kept breaking down, but the DeWalts seemed unstoppable.

Bought mine secondhand out of the US for peanuts..... in fact I have saved SO much money of stuff, I am broke!
