Glock doesn't like Fiocchi 170gr?

[CaptBuzz]

My Glock 23 hates Fiocchi ammo? 3 failures in one magazine? It simply wont cycle it. I tried it again today and after the first round it failed to cycle so I put the box back in the bag and continued the day with reloads and had zero issues. 3000+ rounds of reloads and a few hundred Fiocchi/Winchester/Federal/Gold Dots and now a sudden refusal to shoot the Fiocchi.

Do extractors needs to be replaced every x amount of rounds? Are there any other parts that could cause this?

A broken extractor will not grab the empty case, but your reloads run fine, so that's not it. When you say fail, what exactly happened? Double feed, stovepipe, all the mags, or just one mag involved?

[CaptBuzz]

From what I could see it would fire the first round racked in, fire, kick the brass then click.
I'd drop the mag and pop the round and not even a micro ding.

Reload the round...boom-click. *repeat*

I'll pay more attention to what's going on next time, maybe even take a video.

How old is the Glock? First owner?

A video would be helpful, but from what I am reading, it fires one round, ejects the spent case, and then the chamber cycles in a new round. The new round will not fire, and when you clear the chamber and observe the round, there is no primer strike.

Can you show some pics of the spent brass/primer strikes of your other cartridges (Winchester, etc)? It would appear to be a issue with the firing pin spring if there is little to no primer strike.

Does it fully go back into battery after the first shot?

^^^Forgot to ask!

Could also be a need for a new recoil spring as well.

Is there a round in the chamber?

If there is a round in the chamber is there a dimple on the primer?

If you put oil/solvent into the firing pin channel it tends to gum it up and can cause light strikes. Also the high pressure of the .40 SW destroys the firing pin and causes early and excessive wear.

It takes about 100,000 rounds to get noticeable wear on the striker tip.

It's the ammo. Had the same issues but possibly worse last night with 180gr Fiocchi ammo. No wonder it's 12.99 a box.

It wouldn't feed every so often, sometimes 2 or 3 times in a row and was very dirty ammo.

I had probably 15-20 failures out of 200 rounds.

This is not an ammo problem because the first round fires, chambers the next round, you pull the trigger and get a click. Rack the round out, no primer dent, reload the round into the mag, chamber, then it works for the rest of the mag? Are you running 10 round mags or 13 rounders? Are you starting full at 11(or 14). Are you loading the first round by putting the mag in and racking the slide? And then putting a full mag in?

I have run several thousand Fiochi 180's thru my G23 without a hickup. Fiochi is fairly warm compared to WW

Try this, if you have 10 rounders, only put 9 in the mag. Lock the slide back, put the mag in and let the slide go forward by pushing the slide stop. Number your mags and try this on all mags.

Try pulling your firing pin out and making sure it's clean. Could be that your shooting some dirty ammo and Fiochi has some hard primers. If it's dirty it could slow the firing pin down not allowing it to set off the primer. Interesting how it doesn't even leave a mark on the primers though.

Is it going into full battery and then mis-firing? (Hear the click)

Incorrect; it has been a major issue in my dept.

This is odd. I used to have a personally owned Glock 31 (.357 sig). At the time Fiocchi 357 sig ammo was only 8.99 a box from CTD, which was a steal even five years ago and I ran thousands of rounds through it with no issue.

More recently, my department switched to Glock 23 gen 4's, they were concerned about reliability & recall issues so they had another rangemast and myself run 800 rounds of Fiocchi 170 grain through each one prior to issue to make sure they ran good, again no issues.

On a side note, getting paid time and a half to burn through 20,000 rounds of ammo was both awesome and tedious at the same time.

I was going to add, per the Glock armorer's school, so take it with a grain of salt, the .40 is the only Glock model which specifically starts showing excessive wear after 10,000 tounds, the 9's and .45's are supposedly good to go darn near forever.
