Glocks and a potential weakness.

The other day I was shooting some 9mm reloads that are probably a good 10 years old. The Glock 17 would detonate only 2 out of 15 attempts. The Glock detonates WWB and other common ammunition without a problem. I tried the reloaded ammunition in a friends Glock 19 and got the same failures.

When I try the reloaded ammunition in hammer fired guns, all the rounds would detonate perfectly.

Although the Glock has never jammed, harder primers may be an issue with them.

Anyone have similar experiences?

Call Glolck. Tell them you are having trouble with reloads. They will hang up on you!

Glock says NO RELOADS. Some do use them but they CAN be problematic.

Hard primers or high primers can lead to misfires... in alot of guns. Reloads are fine for range use, and I have run thousands of my own thru many different Glocks without issue, but you should be wary of using them for self defense.

I saw a young man at the range a week ago with a new Ruger P-95. He was shooting a bag of BillyBob's House of Ammo Reloads that he also bought with the gun at the gun show. The gun jammed on every single round.

Gun or reloads? I'd guess the latter.

10 years old and reloads, i'd just blame it on junk ammo and move on.

Don't see how it can be the reloads if they fire fine in a different type of firearm...

But, too little info to pin down why???

How old is the Glock 17 and how many rounds through it?

Maybe it is time to replace the striker spring?

The problem is the Glock is striker fired. An often overlooked fact is striker fired systems do not hit the primer with the same punch as hammer fired systems. A Glock (or any striker fired handgun) has the potential to have more problems igniting hard primers than hammer fired handguns.

Exactly. I don't know if this is an issue with all striker-fired pistols but it is not unheard of for Glocks to have issues with hard primers. I recommend the Wolff 6 lb Extra Power Striker Spring if you wish to continue using ammunition with hard primers.

Have you guys checked the innards of the breech face?

I just detailed stripped the slide last weekend and cleaned out a whole bunch of brass from it. I used a Q-tip dipped in M-Pro7 and came out with gunk. After blowing compressed air through it and allowing to dry...I was back in business.

Just a Glock advice.

It's a 3rd gen with less than 5,000 rounds through it. This problem also occured in a G19. The Glock functions fine with commercial ammo, so there isn't anything wrong with it.

Very interesting.

My Beretta Px4 finished up the ammo without a hiccup.

Thanks, I will look into this.

There may be some gunk buildup in the channel that is keeping the striker from moving freely. I dry fire my G19, then shake it to see if it rattles. If it does, I'm good to go. If it doesn't, I spray it with some GunScrubber followed by some compressed air to clean it out.
