Locking Block Plating Wearing Off

Discussion in 'General Glocking' started by hearsedriver, May 29, 2012.

  1. I noticed tonight that the plating is wearing off of my Gen 4 19 locking block, mainly on the top side. This gun has about 400 rounds through it. Is this normal or anything I should be concerned about ?

    I'm not expert but IMO I shouldn't be an issue. Do you have a pic?
     


  3. Picture added to OP. I do use Hoppes on the barrel but nowhere else on the gun.

    Absolutely normal and I only clean my Glock frames with a dry brush and Q-Tips ;)

    Doesn't look like much has came off, I wouldn't sweat it.
     
  6. Mine looks the same and it will only wear to a certain point and stop. It is normal.

    I polished mine and do not have any wear. When I clean it, I do rub across it with oily finger but not enough where oil is visible

    My Gen 4 G17 is doing the same thing. I was searching the forum for the problem when I found this thread. I wish I could find one of the older locking blocks. My Gen 2 G19 locking block shows no sign of this type wear with a lot more rounds through it.

    Normal wear.
    Hoppes #9 will cause the plating to peel on the block & the frame
    mounted slide rails.

    Sorry, I didn't word that correctly :embarassed: . I meant one of the earlier investment cast type locking blocks before they went to the MIM ones they are now using on the 3 pin models.

    My locking block is actually flaking not just wearing off. Of all my Glocks it is the worst. The others have what I would say are normal wear. I will try to post pictures later today.

    Normal wear. And, Hoppes or not, the frame rails will eventually wear-through. Again, normal on newer Glocks (post-Y2K, anyway, but I'm not sure when the changeover took place from non-plated frame rails). No worries. Shoot the heck out of it. Proper lubrication will slightly mitigate rail wear, but it is inevitable.

    No Hoppes here, being the only Glock I have to do this, I like the OP was concerned when I first saw the flaking. Doing some searching I find unfortunately it is normal. I have a Gen 4 G23 and a Gen 3 G22 with the same type locking block and they do not show the flaking like the G17.

    I dont know how that can be "normal" ? Why is the plating coming off all the parts?? If it is normal, why do they even put the "nickel " coating over the copper?? Why not just make the parts copper to begin with??
    I am glad I do not own a Glock newer than 2004... I have NONE of these problems. :(
