405 Crimson Trace hex wrenches

[saltydog452]

405 g Crimson Trace grip panels on my 638-2 Bodyguard needs 2 (but considering my poor vision and how forgetful I am) needs two...but would like to buy 4) laser adjustment screw wrenches.

If anyone knows for sure the size of those adjustment screw slots I can order mini allen wrenches from Grainger Supply.

Thanks for the assist.
