because i'm not convinced this issue is a feed failure.
it sounds more like a failure to go into battery.
his OP stated the following
that's not a feed failure. if the bullet were stuck on the ramp, it isn't going to go into battery so easily.
sometimes the striker channel liner is ****ed up for whatever reason. anytime i've seen issues w glock failing to enter battery, i've stripped out the striker channel. sometimes they need a new channel liner which is a $1 part. i've found straight up mud in some channels precluding striker movement and thus slide gets stuck partway into battery.
the other issue here is if the firearm doesn't go fully into battery, it can still fire. no bueno. glocks do not have a out-of-battery safety like a sig (oops I used the S-word in a glock thread!)
regardless if the channel is clean and striker moves easily, then that's another potential issue off the table. process of elimination.
