Great product and customer service! Sharp needle is larger guage than hollow point but read review
I was having an issue getting the sharp needle to fit in the gun. It's a negligible size larger than the hollow point needles. I reached out to John and he was very responsive and helpful. Use the provided socket to start the sharp needle into the nozzle... that easy😆. I would recommend emphasizing this in the instructions in big bold letters for people like me that skim through instructions😅. They also have video tutorials that i had overlooked.
I tested it with water and it seals very well. Can't wait to try it out.
Thanks John!
