I always search through ArtStation for subject matter that hasn't been modeled before when starting a new project. I was (somewhat) surprised when I didn't find any caulking guns. Here's my chance to corner the market! But wait, how do I make my work stand out in the sea of potential caulking guns that could suddenly fill the void at any moment? Ah, of course. I will put a scope on it. For the tactical craftsman.
Naturally, I thought about modifying the "firing pin" with CO2 canisters so that the scope would make sense, but in the end, I felt that overdesigning it would betray the spirit of the thing. A caulking gun doesn't ask for more power. Like the turtle, it knows that slow and steady wins the race. But also like the turtle, it doesn't know its full potential until it has a scope strapped onto it.
