Review on Powerful and Portable P6 20L Headless - 4 Inch Length: A Top-Notch Product with Compact Design by Marcos Fiallo

I bought the 1 3/8" and 3/4" sizes to use in my Makita nailer. The 1 3/8" size is one inch and 3/8" in length and works great. However, "3/4" is NOT a 3/4" length. 3/4" is basically 19mm. It's 20mm. It's even listed on the packaging. They are marked as 3/4" AND as 20mm, but as said, 3/4" = 19mm, not 20mm extra length, they tighten up and won't feed properly. The first shot works, but the remaining pins are misaligned in the magazine because the retaining bar is on top, not behind, to keep it level.
