Heavy duty caulk guns

 

— this category includes pistols in which the body thickness is 2 mm or more. This provides increased strength and allows you to work with high extrusion pressure. However the specific extrusion force in such tools can be different, this point should be clarified separately. But what the reinforced body definitely affects in a positive way is the reliability and durability of the pistol. The downside of these benefits is increased cost and weight.
