I bought the large Weston
jerky gun on
Amazon, it holds 1 1/2 pounds of meat, that means less time refilling and it came with some spice mixes, I'm really happy with the large size and it operates very smooth and effortless. What sold me on this make is the ad said, "easy squeeze trigger," being in construction I've used lots of different caulking guns and some work better than others, this gun didn't disappoint me, it is very easy to squeeze.
I also lay fiberglass window screen on my grates and shoot on them, keeps the snack sticks from drooping through the grates, I lay the tip on the screen and just pull and shoot, just before I reach the side I release the trigger, push the release button and wipe the tip on the grate to cut the stick, works fine.
Bearcarver has an excellent pepperoni beef stick tutorial in his sig that I and others use.
