Since grip tape can be used for both legal and illegal purposes, it is regulated by Massachusetts law. Grip tape is only allowed to be sold to adults over the age of 21, and only in certain locations. It is also illegal to use grip tape on a gun in Massachusetts. Doing so will result in a fine or imprisonment. If you are caught using grip tape on a gun in Massachusetts, you could be charged with a felony. So, while grip tape itself is not illegal in Massachusetts, there are some restrictions on its use.
From what I can gather, grip tape for guns is not currently illegal in Massachusetts. However, that could certainly change in the future so it’s always best to stay up-to-date on the latest laws and regulations. In general, though, firearms accessories are subject to the same laws as firearms themselves, so it’s always a good idea to consult with an experienced attorney before making any purchase.
