Does Glock use any MIM parts in any of its handguns?

MIM parts so bad?
Off and on I've read on this forum how serious, die-hard Glock fans prefer Gen 2 and older Gen 3 Glocks due to the lack of Metal Injection Molded (MIM) internal parts. I guess the older Glocks used different parts (machined?). Is the difference really that significant? Does it make the newer...

IIRC - GLOCK started to use MIM (metal injection molding) parts around 2009. Some part examples are the firing pin, extractor and locking block.
FWIW - MIM parts seem to have held up nicely, overall.

Just enough to start forum discussions and debates, but still the No. 1 polymer striker fired handgun in the our galaxy.
And Glock parts are known to be the most reliable not only for their own guns but the P80 crowd too.

Yes, but it’s no big deal. MIM parts have greatly improved since initial introduction. No biggie.
You literally trust your life to MIM parts every day when you get into any recent production car. Many brake and steering system parts are MIM... LOL. Ohhhh noooo...
But.......properly machined billet parts are better PERIOD.
I have done 6 P80 builds and 5 have billet strikers and extractors.
My only remaining Glock is a Gen 2 built in Austria in Feb. 1990.
No powered metal critical parts for me.

I don't know and I don't much care.
What I do know, I have way over twenty-thousand rounds through my G48 - not one malfunction.
One caveat: when I ran 1911's (Baer, Brown, Colt (70 & 80 series) and Detonics) I always went with this sear.

The last two I bought were polished chromaloy steel from Spinta Precision in California.
I have also used their 9mm billet extractors.

New here. The striker was not MIM in 2018 and should not be now. Expensively turned and milled from a finger thick rod.
This, the striker is still a machined part.
The only MIM parts in a Glock are as follows: Locking block, extractor, extractor depressor plunger, and the firing pin block.
That is significantly less than the amount of MIM parts found in most other modern pistols.
And seriously, MIM is fine anyways as long as it is not made in India cough

I have to laugh at the level of absurdity people in the gun world push themselves to and the knots they twist. Back when I was shooting high-power everyone argued over which was better a forged M1A receiver or a cast M1A receiver,,,
Well,,,a cast M1A receiver had an estimated useful life of over 120,000 rounds while it was expected a Forged receiver was good to 400,000 rounds. So obviously a forged receiver is better... But at a dollar a round for match ammo and a new $500 barrel about every 5,000 rounds you are quibbling over a service life of a $600 receiver (Maybe $350 back in the day) after spending about $140 k on ammo and barrels....and how the forged receiver is so much better...LOL. C'mon. Get real. Forget the fact that I used to shoot against some boys own the Tennessee National Guard rifle team and they routinely cracked the USGI forged M14 receivers...LOL.

Been fooling with the works inside a Smith 25-15, which are entirely MIM, except the hammer block. It isn't as elegant as the older, forged stuff, but it is still remarkably well fit, and can produce a smooth action.
Would I prefer the older stuf?. Sure, and a gun that costs less than $2000.
Can't say I'm uncomfortable with good MIM.

Some still don't realize Glock has long since moved over to MIM strikers / firing pins.
The old machined firing pins will have tool marks.
The MIM pins will have a slightly gritty surface texture similar to the locking block and also have notches around the nose to identify the caliber (molding marks). These pins also show a hint of copper from wear.
The old pins had rings or the caliber marked on the tail end of the lug and could turn black from use (like any steel does when burnt).

Disassembled a lot of Glocks, never seen a MIM FP. I know they made and tested some, but their fanatic obsession for confidence will not allow to put a MIM FP in the pistol. Actually, I believe that the FP from a Glock is the third expensive part - after slide and barrel. All other parts in the pistol are cheaper, even the frame. Just checked my gen5 G17 - turning marks on the FP. No MIM.
Extractor claw, locking block and firing pin safety (gen5) are the ony MIM parts on the Glock. And also the iron sights.

That is the most poorly finished striker I have ever seen. Nothing like the striker in my Gen 2. None of my after aftermarket strikers are near that ratty.
Glock Perfection indeed!

Macrophotography with increased contrast to show it's not MIM. You won't see this good with bare eye.
My gen3 FP looks identically - no problems so far.

Gas turbine blades are MIM. Each blade on the high speed turbine of a jet engine produces 800 horsepower, as much as a NASCAR engine. They do it at 3000 degrees c and turning 25,000 rpm. And they do it hour after hour.
Glocks with MIM extractors run hundreds of thousands of rounds. I carry a G19 with MIM extractor. If the gang approaches, I have confidence.

Glock strikers have been MIM since sometime in 2009 . That's the facts jack , the only issues I have heard of have been premature wear with green ammo, but this also occurs on the breach face and extractor , it also happens on tool steel strikers as well.

I get a kick out of the people that think they have to spend money on aftermarket billet extractors. The OEM LCI extractors hold up just fine. Plus like on any firearm, the extractors aren't meant to last forever anyway. You should be checking them periodically along with all springs and replace as needed.
On firing pins, there is OEM MIM and junk aftermarket MIM that will fail. One of the worse aftermarket firing pins I have seen in the last couple of years is the Lone Wolf firing pins. I've seen a lot of them break. On other aftermarket firing pins I've seen where the front is not long enough and can cause light primer strikes or the striker too short and cause bad sear engagement.
