Notes and Observations:

I want to love this gun but the BTF is driving me nuts. The trigger is smooth as silk and probably the best glock trigger I own; but the BTF is infuriating. It seems to happen mostly with weaker 115gr brass cased ball like Blazer or PMC. As I said in my range log, I am starting to wonder if it isn't the extremely dusty climate of my range combined with the tight tolerance of the Apex part. I may swap the apex FRE out for an OEM extractor as frankly I didnt give it much of a chance in that configuration.

That said either way this gun went 2k rounds in this configuration with no malfunctions, even if it does like to pitch brass at my skull. No BTF with my 147gr carry loads either. I gave it a solid cleaning and will be comfortable carrying it after I run another box or two of HSTs through it. Fed 50 147gr HSTs and 168 147gr Winchester RA9T Ranger Ts through it w/ no issues. I may tinker with it some but I would trust my life to it in its current condition.

To update: i shot this gun this weekend with 124gr RUAG. Had 1FTF with a magpul Gl19 mag. Disappointing. The gun otherwise ran like a top with OEM mags, so I wonder if it was the dirty Magpul mag.

Minimal BTF. Maybe 1? out of ~100rds.

As much as I like Magpul's AR-platform stuff, I've heard far more issue reports with their Glock magazines than I have with OEM.

Anecdotal, but my two cents anyway.

Same. In running through my logbook, I have at least 2 other failures with this gun or my other Gen 4 G19, vs only 1 with an OEM mag.

Comments:
Other than the factory up grades to this pistol I stippled the grip instead of running the provided Talon Grips, installed a spurless hammer, and a #12 Wilson Combat hammer spring

The one stoppage was a failure to lock open on the last round. This was caused by me riding the slide stop lever.

Followup to my last post:

It appears that at least one of the 4 FTFires was due to a slightly high primer. I've adjusted primer seating in my 1050, and have had no issues for the last 600 rounds.

Comments:
Brand new gun. 3 Malfs were the trigger not resetting. Happened on rounds 102, 402, & 1,575. I dropped the Mag, worked the slide, and we were GTG.
Probably something I did wrong, just had back surgery and was taking happy pills.
All Ammo was my reloads and they did fine.
No BTF!! I like the Autoforwarding feature.
I plan to strip the gun, clean it, then add an aftermarket trigger. I fired 700 rounds one day and my finger was not happy!
Will be waiting patiently for some Ameriglo sights.
This is a nice companion to my 3 Gen2 G-19's.

Too late to edit, but I found a solution to the trigger not resetting. Member earlan357 @ czfirearms.us posted a video with a fix.

Comments: The only mods that I made to this gun prior to the commencement of the Challenge were the excellent Ameriglo Defoor flat black steel sights, lubricating the pistol and adding a Glockmeister grip plug. I’ve found that with my Gen 5 examples, the trigger is “just right” out of the box, giving me a very smooth rolling break.

Today, I turned in a 93/100 (3X) on the Hackathorn Test at 25 yards, without putting a terrible amount of effort into the test. I could attain an even higher score with better quality ammo and taking a bit more time. I’m very pleased with the 17.5 and recommend them to anyone.
