Picked up a used C9 and everything's fine except the rear sight is chipped. I have a replacement sight but I didn't get one of the allen key tools to take out the second screw on the sight. Does anyone know what size it is?

Thanks

I usually just start trying allen keys until I find one that fits.

LOL! That's my usual technique too!

I'm guessing he doesn't own any hex

Yeah, just buy a set of hex wrebches and you should have one that fits.

Don't forget to get some "millimeter" (metric) size of allen head wrenches also. I've found many screws nowadays being millimeter over using ASE that are measurements to the USA.

Yup. Harbor Freight has a fairly complete set of both pretty cheap. Mine came as a set of each in one package. With the coupon, cost me about $5 - 4 years ago.

I do buy a shed load of stuff there. Wouldn't want to make a living with some of it, but it works fine for an old dawg DIYer. Usually way cheaper than the orange giant or the blue monster.
