My father sent me this with an admonition to immediately throw away all the metal caulk guns I have, since I will never want to touch them again — and I have to agree. This one has an integral spike to break the internal cartridge membrane. It’s lightweight but won’t break (nor will it break anything else) if you drop it. It’s as strong as I have ever required, has never jammed or failed in any way, and the orange color is easy to find in the tool cabinet among all the other junk. As a Victorian homeowner, I use it several times a year and have had this one 3-4 years now. If I were to lose it, I would put off a caulking project until a new one arrived in the mail.
