EAA Witness Polymer 10mm Pistol

CS8161
I an trying to figure out what size hex head driver I need to loosen the two set screws on an EAA Witness rear sight. I want to drift the rear sight slightly to get it to shoot to point of aim. Anyone have one of these pistols and know what size driver is needed?

    Chances are being it's made in Italy, their metric. Don't screw them up by by trying to use U.S allens, if they don't fit correctly. Most auto parts stores carry metric sets for not a whole lot of money. If you have a caliper you can measure them. The small metric allens usually run from 1.5, 2 & 2.5mm.

    For what its worth, here's the gun manual. I don't think it contains the information you want, but its worth a look:

    +1.

    For what its worth, you should be able to pick up a COMPLETE allen wrench set with 15 sizes EACH of Metric and US/Imperial for for roughly $20 or less at any hardware store (or Sears, or Walmart, etc).

    Thanks, I just got back from Home Depot, bought a whole set of metric allen wrenches...one of them has to fit!
    Update: Yep, it was the 1.5MM wrench that I needed!

    Glad to hear you got it adjusted OK.

    Out of curiosity, how do you like that EAA poly 10MM? How does it shoot? I have been considering one for a camp gun. It has to be reliable and accurate, mostly for protection against a a black bear.

    BTW...10MM is the only standard auto I would consider for that task.

    I shot about 60 rounds thru it today and 50 yesterday, no jams, no stovepipes, no problems. Accuracy was excellent but recoil, due to the polymer frame, is stout! The trigger face is not smooth and after about thirty rounds, my trigger finger was bleeding. I am going to have a gunsmith smooth out the trigger face and that should alleviate the problem. I was impressed with the pistol, loaded with 15 rounds of Buffalo Bore or Double Tap full power ammo, it would make a formidable woods gun. I plan on carrying it up on the mountain where mountain lion and black bear roam.

    I'm glad the metric allen worked out for you OK! It's funny how many Stateside gun guys don't realize that their are European firearms with metric allen screws, that aren't compatible with US fractional allen wrenches.

    The most amazed I ever been about about people trying to use/misuse U.S. fractional allens, was at Marks old stamping ground the Stockade. Sam had got his hands on a bunch of Browning GP Competition High Powers somehow. Every one of the had the allen screw that held on front muzzle weight buggered up. Some imbecile had deliberately driven a U.S. sized allen wrench into the allen screw to enable a U.S. fractional allen wrench to fit. Even back then GP Competitons were pricer then regular High Powers, the buggered screws really detracted from their value IMHO.

    I know enough not to do that, I hate buggered screws on a gun, looks like Bubba got his hands on it! I won't buy a gun with buggered screws, who knows what was done on the inside if the outside screws are all chiseled up! [;)]

    The Double Tap ammo like you mentioned is the way to go. I have around 70 10mm auto's (well over half my entire gun collection) and there is very few other loads that do the 10mm auto justice.

    I had a trigger job on my mid-90's era Witness and it really made a slick shooter. I have since sold or traded it but it was a good gun for the money. In fact, I think I accidentally sold it without the cleaning kit and extras if you know anyone looking for a set.

    I have found that a set of metric wrenches can be had in a pawn shop for very little money.
