    The pin that holds the release button in my Mark IV Hunter works loose and moves out after shooting 2/3 10 round mags. gonna call Ruger tomorrow.
    It also shoots high at 25 yards about 2" with a 6 o'clock sight position hold, screw on the rear sight is bottomed, shim front sight up? or see if I can lower rear sight blade?

    I called Ruger Customer Service today, I spoke with a lady named Angie( I hope she won't be upset I mentioned her name here?) I explained my problems and she gave me a suggestion on my sight adjustment and she said she would ship out parts to me for the pin shifting, first she ask to send the gun in, I then ask if possible I not send it in and I also shoot in a competition this weekend, she agreed and said she would ship parts out to me, THANK YOU ANGIE!
    I have to be honest I have dealt with many customer service people in the past, It was so pleasing to deal with a lady that listened and agreed to go out of her way to help me ! She is the best and I feel the same for RUGER. Thanks Again Angie!

    This is a well-documented issue with many of the Mark 4s, the walking out of the grip-frame by the pin that holds the lock button/bolt stop in the frame. There is supposed to be a small spring under the release button that fits in a groove in the pin, but the pin walks out anyway. Probably the groove is not deep enough or the spring tension is not enough or a combination of both. Ruger will fix it, but they want to have the gun to do it for you.

    Thanks but if you read my next post on the 10th of Oct, I called and spoke with a lady named Angie and she sent me new parts to fix the condition, I installed them myself and have had no problems, it is a bit tricky but if your use to working on guns/springs it's not a bad job, Angie was informative and helpful and said I could send it in or I could do it myself.

    Yes, I saw that, but many other folks, if not most, have said Ruger wants the gun back to do the fix. You are the exception. I am glad they did send you the parts and you were able to do the fix. Can you mention what the parts were, and say what differences there are between the new and the originals?

    They sent me a new pin and spring, from what I could tell the parts are not different other then the spring is bent a bit farther apart to create a bit more pressure on the spring, almost like they spread it a bit farther so it puts a bit more tension on it, after I did install and compared the parts I almost wonder if I just stretched the spring out a bit it might have worked. note I did notice the new spring that has more tension on it is more difficult to install than the original spring was.
