Is the installation of the Radian magwell for Glock 43X MOS difficult?

The installation is considered intermediate. It requires careful attention to detail, particularly with the expanding plug and the detent mechanism. Basic mechanical aptitude and the use of included tools are necessary.

What tools are needed to install the Radian Magwell on a Glock 43X MOS?
