This is my experience: both are unreliable for different reasons.
The $130 Apex starts out feeling like an improvement. I bought it because the stock trigger pull of my 17 gen 4 was too much and I couldn't keep it on target and pull the trigger. So I got on the internet and groggled "better trigger pull on my Glock" and saw all the lovely, Glowing reviews of the Apex trigger and others and bought the Apex.
But after about 50 dry fires it starts changing and after about 200 changes significantly with the pull getting longer and longer until your pistol will not even fire anymore because the trigger is now travelling all the way back up against the back of the trigger well before it releases the firing pin. Back on Groggle, I for the first time found info exhorting Glock owners to NEVER USE ANY aftermarket parts on their Glocks, especially triggers and even to avoid Zev barrels. I also learned at that time ,many days late and $130 short, about the GLOCK minus connector and got one on Ebay and installed it, trigger pull issue solved.
So this year, I got a Glock 45 gen 5 and it has a slightly gritty take-up and a mushier break than my Gen 4 17 and i learn about the new GPT and got one from GS.com. It's supposed to be for gen 5 only, but I put it in my 17 last May, deciding to sell the 45, and it worked fine. I didn't like the flat face trigger shoe, so I removed it and put my OEM shoe on it. It worked fine and was even better than the stock trigger with the minus connector until today when the housing shattered!
How it shattered is a mystery but why is not: The housing of the GPT is hollowed out below the trigger bar to literally construction paper-thin walls in 2 places (where it shattered) to make room for all the extra trigger components underneath the trigger bar. Note that in the gen 4 housing, the only trigger part in the middle of the housing is the bar itself with a hook at the bottom that connects to a spring in the back, leaving a lot more housing material in teh front and side than that of a GPT housing.
Today I did get the slide jammed on and had to take it down by removing the back plate and the slide parts out the back. But before I did that, I kept trying to remove the slide by pressing back and forth pretty hard on the slide and the barrel. That's the only thing I did to it untowards that could have broken a flimsy part like the GPT trigger housing that I didn't know was that flimsy until it broke.
But note that in the past, I'd done the same thing to it and treated it worse with the OEM trigger assembly installed and it didn't shatter.
Now, words about things I read today about another aftermarket trigger, specifically a Timney for Glock: one blog poster said he had to bend the tab on the end of the bar to keep it from not releasing the firing pin! That begs the question why he could even bend a steel part that is supposed to be so strong that if enough force is put on it to bend it, in a vice, like he did, why it didn't break before it bent at all like all good steel gun parts should?
Another review said drop testing a Timney trigger installed in his Glock on a shaggy rug (not a steel plate from 2 meters like in the 1982 Austrian military trials that the P80 passed) made the trigger release almost every time. But the very first bad review I came across for a TImney trigger for Glock, said it wore out in short order just like the Apex did!
Note about OEM gen 5 trigger housings:Tthey also appear to be not as robust as the gen 4 housings. w the same material missing at the front of the housing like on the GPT in an area where the gen 4 housing is solid. I note this bcuz the first thing I did when i discovered the GPT housing shattered in my gen 4 17 was to take the trigger assy out of the gen 5 45 and install it in my 17. But first I compared it to the GPT housing and it was the same. Still not satisfied, I got out the 17 housing and saw that it's solid in the areas where the gen5 and the GPT are not.
Also selling the 45 MOS, which is black and a nice straight shooter, is getting like a $200 haircut. I thought I got a good deal on it at $650 and now can't give it away, even after stripping the sights off and selling them separately, for more than $450 after having it for 3 months up on Gunbroker.com with all the accessories and unused magazines in the box it came with. 45s aren't in fashion I guess.
For those not in the know like me, the 45 gen is a 19 with a longer 17 grip. Being Gen 5 means it has an ambidextrous slide catch with a internal coilspring (loperation of which is a complete mystery to me) a coil compression spring under the takedown lever instead of a leaf spring and a leaf spring in the trigger housing instead of a coil tension spring.
And the moral of this here story is: Don't be dopes & put no aftermarket shiite (or GPTs) on yer Glocks.
Oh, And don't buy a new 45-5 and expect to get nearly the money you put into it back out a short time and a few rounds later.
sleep tite.
