I know Mack is going to chime in and try to make me feel bad
because I broke an almighty Glock part. I’ll preface this by saying that it
wasn’t a true piece of tupperware but it still had their guts. I somehow
managed to break, not the normal way, a Glock firing pin. This is the first one
I’ve broken like this, but surprisingly (or not), I’ve broken 2 other %100 Glocks
prior to this. I’m what you would consider “hard on stuff.”
So, let’s look at some facts and then try to diagnose this
break. (A quick aside, I was only able to find one other article on the entire
interwebs about a similarly broken firing pin.) Not exact numbers, but I have
fired roughly four thousand rounds of NATO spec 9mm, another two thousand rounds
of various ammunition, mostly steel cased, and probably put about another two
thousand dry fires on my “Not-a-Glock”.
How did I find out it broke? Thank goodness I was dry firing
when I found it. I was shooting invisible holes in my light switches and all of
a sudden, my trigger wouldn’t reset. I looked in from the rear of the slide and
it didn’t appear anything was catching. I then took the slide off and saw the
rear portion of the firing pin that catches on the trigger bar was floating
back and forth. So, off came the striker plate and out falls all my little
striker pieces including a new piece that wasn’t supposed to be there. After
pulling apart some other tupperware like pieces and swapping parts like Tuco in
The Good, The Bad, and The Ugly, I got that gun running again. But now I’m standing
by for everyone’s favorite Counter-Jockey/Glock Armorer to make sure I don’t
break anything else.
I spent awhile scouring the depths of gun forums everywhere
looking for what may have caused this or similar mishaps only to find a single,
one-page conversation about the same type of break. After all this searching,
the creator of this conversation never actually pin-pointed why it broke. Luckily,
I get to be around amazing men every day that put Uncle Sam’s hard-earned tax dollars
to work. After a quick conversation with our Company armorer, it appears that
the culprit is definitely the NATO spec ammo. (NATO spec 9mm is usually hotter
than normal +P so it has some oomph to it.) He also confirmed that while an odd
break, it is not out of the norm for guys who put a lot of NATO spec ammo
through their guns and has happened to a fairly good number of people in my
Company. We shoot the wonderful plastic fantastics that come in 15 and 17 round
flavors for work.
This just reiterates that no matter how “Perfect” your firearm
may be, it is always good to have a spare or some spare parts for just these occasions.
Welp, time to get back out there and see what else I can break!
Hey Pudge;
ReplyDeleteEven though you shoot the "Plastic Fantastic" Firing Pins are metal and those over time will suffer metal fatigue from heating and cooling, or as we call it in the aviation business "Cycles" and over time metal expands and contracts on the micro level from the heat and eventually this generates microfractures and one day *Surprise!*. That is why we track plane parts and airplanes so strictly. Lawn darts are rough on the company stock on the NASDAQ.
Now go out there and have fun and poke Mack with a stick...keep him stirring.
Mr. Garabaldi,
DeleteI never thought about the heating and cooling cycles that I've put this particular handgun through. I'd say on average, every 4 out of 5 range trips this gun got ran extremely hard and heated up more than the average range plinker. I appreciate the info. Good to know smart people! I'm sure those big lawn darts cause problems for everyone.
He's moving about now but I'd hate to prod him too much.
