    Can anyone give me some guidance on adjusting my sights! I have to hold to the right and at 3 o'clock position to hit target dead center. Do I need special tools or is it best left to a gunsmith!?

    Afternoon Mountainskytop,

    Make an adjustment to the front sight that follows that direction. For example, if the bullet is hitting right of the target, adjust the front sight by moving it to the right, or move the rear sight in the opposite direction of the POI.
    Your stock sight is what some call "combat sights" where you have to cover the POI to hit it. This is what I used to adjust mine after I replaced the rear sight with the Sig rear sight. You will only want to move either sight you pick about 1/32 at a time.

    ***More info***
    My rear sight seemed to be a little loose so Bersa put some glue under it to hold it. When I replaced the rear sight I seen it and had to remove the new one to put more glue on for it to hold as it was loose, not much,, but a little. I think they cut the dove tail wrong. The front sight is nice and tight and can be moved like it should be with out the glue. The front sight is metal as the new Sig sight is, but the rear Bersa sight is a plastic.

    I just took a close look at my sights for the first time and the rear sight appears totally out of whack toward the left and apparently needs to
    Be tapped to nudged to the right to correct my sighting POI issue previously described as I have to aim to the right if the target. Now apparently I gotta find the way to tap that sight gently to the right to correct the problem! I don't have a too to do this. Any suggestions? Thanks!

    As you seen in the picture I used a wooden dowel and a small hammer. The sights go in and come out From the left side. Mine looks like it has a lip on the right side so you don't want to go past that point. You want to "TAP" not hit the sight. 1/32 or less at a time. You'll be surprised at how little movement of the sight will give you a LOT of movement at the POI. BE CAREFUL and do it slow and easy. You might have a spring under the rear sight or you might not, mine doesn't. If for any reason you have to glue it, you don't want to move it to far over so the spring will fly out. (tap only)

    IMPORTANT
    Tap at the base of the sight, not at the middle or top.

    Thanks for that sight adjustment input! I gotta get a small hammer and dowel now to tap that sight into position .

    I think Bersa firearms ROCKS!

    I tried tapping the sight to the right but it hardly moved. Put some oil on it this morning and will see if that helps! I used the body of my Swiss Army knife to try to tap it but I guess i really gotta get a small hammer and dowel to do it right.

    The rear dove tail on mine looks like it has a stop on the right hand side so you can't go to far to the right with that one. From what you said tho I am guessing that you are trying to move the front sight to the right. They are wedged in to keep them from moving, they need to be tight.
    If you don't feel comfortable doing it then take it to a gun shop and have them do it. Altho they will have to fire it to check the adjustment. Can you take a closeup picture of the front and rear sight and post it here??
    Remember,, the front sight is medal and it could mess up the dove tail cut in the weapon if moved to far.

    You can tap the sights left or right but you will need to use a brass bar or another "soft" metal so you do not mar up your gun or mess up the sight.. TO correct the issue I always move my rear sights. For your issue, move the rear sight to the left. Tap it a few times lightly, then test. If it needs more then keep doing it till you get on target. Another option is replacing the sights (both) with a set of adjustable combat type sights. Not too expensive and any gunsmith will do it for you.

    Thanks for the sight adjustment info help. Just to clarify, it is the REAR sight I am trying to tap to the right as it is way out to the left. Hopefully the oil will free it up and I will try tapping it again. If no luck guess a gun smith might be in order. Thanks again for the info.

    Ok I've had to tap my rear sights before so I clamped my pistol down using rubber to keep it from scratching, then used a 6inch piece of 2x4 because its heavy and solid enough and used a heavy hammer to tap it. Start lightly but increase your force till it starts moving.

    The great gun store where I bought my Bersa loaned me a brass punch and advised me to lay the pistol on a heavy folded towel and tap the rear sight and that should do the trick of finally moving the rear sight into position. Stay tuned!!

    Using the brass pinch loaned my by my gun store did the trick and I was able to finally move the rear sight. Now just have to fine tune this on the range. Thanks for all
    The help here! This is a awesome forum!
