One rear sight screw on my Wilson EDC X9L started backing out after about 675 rounds. The sight did not move due to the notched sight mount.

I tightened up the screw with the provided allen wrench... finger tight while pushing on the “small” end of the wrench... then a little tighter pushing on the “longer end” of the allen wrench.

I was cautious not to over-torque the screw, but I did apply moderate / firm force... about as much as I felt the screw could reasonably take.

Did I do the right thing?

Small screws can be over torqued and often is suggested not to reuse them. Using the short end of the allen works well on the initial install if a torque driver is not used.
Clean the threads and use a "drop" of blue Loctite and re install.
The Loctite basically stops the screw from vibrating loose.
