I shot 100 rds of hot ammo with a 22 lb ISMI spring. No FTEs. I will try another 300 rounds of hot ammo with the 22 lbs spring. If not FTE's I will consider the problem solved. From what I have read, the G40 slide is thin walled and weighs a few ounces less than a G20 slide. This may be a reason more spring is needed on a G40.

I put in a brand new LCI extractor, spring, SL bearing and plunger from MidwayUSA. It certainly did HELP the problem. I only had one malfunction in 60 rds of hot ammo. I'll be trying the heavier recoil springs soon.

I will swap in a new extractor, spring, bearing and plunger and see if the problem persists. I have some heavy recoil springs to try if the problem remains.

I swapped in a brand new Glock ejector. It did not fix the issue. These malfunctions ONLY occur with VERY hot ammo (Hornady factory 180 gr XTP loads, all Underwood 180gr + hollow point loads) I do not have issues with mediocre ammo (FMJ practice ammo or Winchester 180gr Silvertips).

Yes I hold pistols with a thumbs forward grip.

I will swap in a new ejector and see if that helps.

This is a brand new Glock G40 (10mm). This happens sporadically with several varieties of factory ammo...Hornady and Underwood. Maybe 1 in 25 rounds. I'm guessing ejector or extractor.

Has this match been canceled?

I tried this mod and was pretty unimpressed. My 1050's run a lot better without the bearing IMO.

Are you sending out email confirmations? I sent in my check and app like a month ago and have not heard anything and my check remains undeposited.

Those in the know have piles of them.

With CProducts 40rd round mags I can run out to 2.27" reliably.

Very nice job! It's good to see jobs done properly with a mill and not a dremel.

Daniel used a 10.5" at the first and 2nd 3GN pro matches.

Long tubes can be very advantageous. It's not really about cramming in an extra couple shells at the buzzer. It allows a more flexible loading plan that could potentially save some amount of time.
