NO it isn't non-drip. Every sealant gun has a clip/tab that YOU press to release pressure and cut off the caulk/sealant stream - NON-DRIP guns do this AUTOMATICALLY but they cost a bit more, BUT in the long term you will save money on spilled sealant and your finishing will improve.

What is the Thrust Ratio of this gun

I dont know the exact answer but it's an amazing mastic gun I use it all day quite alot it's very good

How do you get the cartridge into the gun ? The silver bar is solid to the end of the gun ? Is there a release button somewhere?

press the silver lever in at the back of the gun and pull the hook back while lever is depressed

Solid made & fits various sized tubes.

This is a very well made holder. Tne good news is it takes both 330 size tubes and the longer 380 tubes. Little more expensive than some and heavier than my other holders - but I think it will have a longer life. Recommended

Product Quality

This caulk gun is worth the money compared to most caulk gun's I've had in the past. It feels strong and comfortable to use. Like how you can twist the gun to where your caulking to in which makes the job alot easier. Can not fault this product for the cost. Even bought another one for my work colleague as he was impressed with the product. Definitely will look out for ox products in the near future.
