Problem with titan. safety plunger?

[jdgardner]

upon disassembly I noticed that the titanium safety plunger was being beaten significantly.  Many peen marks on the lowest part of the upper portion (not the part that protrudes). This is on a Glock 21.  Factory striker. So far hasn't caused a malfunction, but this is the second time I've had to dress with a file and clean up with a stone.  trigger bar seems to push it up out of the way sufficiently. Anyone else had this problem? Thanks, John

John,

Do you get any light primer strikes?

JD,

During this past weekend's polishing expedition of my Glock 30 I noticed my firing pin safety plunger has these same peen marks (a factory plunger but I do not know what the material is).  They were not deep, simply noticable.  I went ahead and polished all of the bearing surfaces, put it back together and it shot like a dream.  No problems.

I have some very minor dings on my safety plunger as well.  I can't see anything that would cause them in normal operation, but did notice that the edges where plunger hole meets the firing pin channel are sharp and a little rough.  The damage might be from installation/removal.  

But, if your plunger is that soft, why not put the $3 Glock one back in?  It's tough to believe that the miniscule weight difference is getting you that much mileage versus the consequences of a safety system malfunction.  

Just my $.02,

Eric

Remove the extractor. Does it also have "dings" on the top side edge of the half circle recessed area?

I'll bet that's where the dings on the plunger are comming from.
