Rear XS Sight

[ad5md]

Okay, now I was able to install the sear and spring on my M&P Shield and need to take the rear XS Sights out to change the USB and spring. I lost the allen wrench that came with it and it seems that it is not a standard one (tried several sizes from my toolbox-nothing fits). Anyone out here with the same sights who knows the size of the allen wrench? Tnx

If none of your standard wrenches fit, try some metric ones.

They are very helpful folks - call or email and they will provide an answer promptly.

I think it's 0.050.
