The Amazon Basics Heavy Duty Sealant Caulking Gun is designed to handle standard 310 ml caulk cartridges, making it suitable for many home improvement and repair tasks.

In terms of comfort, the aluminium handle with a rubber-coated plastic grip and trigger helps reduce hand fatigue during longer use, making it easier to work on bigger projects.
