    photos below are the internal lock flag I removed from my S&W M&PR8. This is my first and only pistol with about 3000 rounds through it, 85 of which were full power magnum rounds (I have the second half finished box right here)

    Anyway I was at the range shooting target loads. but I had some 357 mag Winchester Super X 158gr JHP rounds in the bag which I like to shoot a few every now and again. So I will be better prepared if ever I needed them.

    So I loaded up the magnum rounds and after the second shot the revolver 'seized' 'bound' 'locked'. I am not sure of the terminology (Im Australian) and would not fire. Couldnt pull the trigger or the hammer or open it.
    After a small amount of wiggling and jiggling it seemed to free itself up.

    Dry fired it a few times and it seemed fine.
    I fired a few more target loads but I noticed the trigger felt a bit rougher than before, in the initial range of movment, so I thought it was definately time to pack it up.

    Got home got on the net and did a lot of reading and opened the pistol up and see if there was a bit of something inside it making it misbehave.

    Took it apart and while there decided to remove the internal lock just in case it was the culprit, as I had read of accounts of the lock giving some ppl trouble with lighter revolvers and heavy loads. Other than that I had no reason to think it was the lock and didnt really have anything against this contentious item.

    Upon removing the 'bolt' (I think it is called) I noticed some what I thought was wear on the frame, under the bolt, but it actually rubbed away so I think it was a bit of ground up metal.

    In fact I now think it was a bit of ground metal that had broken off the internal flag part of the lock.
    Unfortunately I am not sure exatcly what this piece should look like. Its hard to find a clear shot of it on the net. But the ones I could find make my piece look like it has a chip out of it in the bottom, near the semicicular cut out where the spring is visible

    See photos below.


    the pen shows how tiny this bit it and points to the bit I mean DSC_4525.jpg

    This is the best photo of the flag I could find on the internet. Notice it doesnt looked chipped !

    I was one of those guys that said I dont care about my internal lock because you never really hear any confirmed stories about it going wrong.
    Needless to say that opinion has changed
    Thought the good folk here might appreciate the opportunity to comment ;)

    Of course these is a chance that my piece is meant to look like that, which is why this post is here. If it is meant to be that shape then there is something else I need to find wrong with my revolver ;( as I want to know why it locked like that.

    A shooter at my club (whom I trust) has also had an ILS lock up on him; in his 329PD.

    Saying it can't happen doesn't make it so, as you found out. :)

    Now when you put it back together, just leave that part out, if you can. Check out the Smith & Wesson Forum for detailed accounts of How-To.

    I would call S&W and have them send you a call tag so you can send it back to them to show Saf-t that their parts arent worth a darn and not made right. Also tell them the Klinton era is and has ceased for a long time now.

    I for one hope they keep the locks. It will save me from having to buy a s&w revolver

    That part appears to be MIM!!?? :eek:

    We have it on good authority (ad naseum) that MIM parts don't fail!! They are < insert your favorite percentage > the strength of forged parts!!

    I'm sure the Safety Wesson apologists will be along to assure you that what you have experienced did not happen. IL's never fail or malfunction, its all internet rumor! :rolleyes: It was probably just a high primer, or powder under the ejector star. :rolleyes:

    Of course S&W has the best customer service.....I wonder how they got that good?......evidently by getting lots of practice! ;)

    You paid alot of money for that gun.....good luck!

    internal locks do not fail
    mim parts are 100% reliable

    you are obviously a conspiracy theorists that created this fiction

    current Smith and Wesson revolvers are the best in the world and never break

    I just talked to Jeff at Smith and Wesson customer service and he will look at your pics and he wants you to call to tell him about the breakage of that spring. I told Jeff that the ILS ;ocks are not being made right because the parts are kinda weak and not going thru quality control as the parts are suppose to. And also aknowledged to him that the computerized machinery that these parts are made from need maintance every so often and the drives and software replaced. Call Jeff at 1-800-331-0852 and discuss your problem with him.
