    How many of you have replaced a defective locking block?

    I have Gen 4, Glock 34 that just would not shoot as well as my other Glocks. Over the years I have probably owned about 25 Glocks and this one specimen just would not shoot. Had a Glock Armorer look at my gun and he replaced the locking block. Gave me the old piece back. It was readily apparent this part had uneven wear on the different sides. Gun would run 100% just not shoot well.

    Just wondering how common this is.

    I've replaced G34 locking blocks because I found that some loose ones were causing accuracy problems. Here's a long post on the topic:G34 Gen4 Locking Block Broken

    I don't have a source, but I'd guess five of us.

    So, how did you determine ypunhad a problem, was it simply due to uneven wear?

    In my case, a brand new G34 was shooting left or right, consistently ( I forget which side, it's been a while. ). Comparing the fit of several locking blocks in the frame, I found that the tighter the fit, the more accurate the pistol became. So, I swapped out the locking block and the problem was solved.
