Bit Embarrassing but ...

Does anyone happen to know offhand or can check to see what size screw a Wilson 2011 trigger uses for overtravel adjustment? I stripped the gun down all the way and somehow managed to lose/misplace/send into oblivion the little allen overtravel screw and I cannot find any reference to what size it is. Would save me a call to Wilson and bothering busy people trying to help people with actual issues.

Can't seem to find the answer myself, so I would suggest calling their customer service and put them to the test and more than likely they'll send you one.

Other than that, bring the trigger and 1/16" allen wrench to your local Ace Hardware's screw area in the back and try out what they have. I get most of my odds and ends gun-related screws from there.

Wilson comes through, 6-32x5-16th" screw, in case anyone was wondering

In general, if you know the allen wrench size, you can usually figure out what the setscrew size would be.

0.050" wrench goes in a #4 setscrew.
The most commonly found #4 fastener will be 4-40.
1/16" wrench goes in a #6 setscrew.
The most commonly found #6 fastener will be 6-32.
5/64" wrench goes in a #8 setscrew.
The most commonly found #8 fastener will be 8-32.

Then there are non-typical ones like 5-40 (1/16" wrench) and your fine or extra fine threads like 6-40, 6-48 etc.
A 2mm wrench happens to be almost identical to a 5/64" wrench so watch out for metric stuff too...
