I just got a brand new glock 42 and I'm frustrated as heck. I shot 24 rounds of ppu and 24 rounds of Winchester white box. Stove pipes and failure to eject EVERY shot. I am pissed and now bleeding form trying to clear one of stove pipes. I then switched to Hornady critical defense. Shot two mags full with no problems at all. Not sure why this worked but not other fmj stuff. I must confess I didn't clean and lube as I should have. Any suggestions. Shooting ammo that's a dollar a round is going to cost too much $. My glock 26 functions 100% even when dirty and unlubed. I'm stumped. Suggestions?
 
Did you strip, clean and lubricate before shooting? Firearms often come with gunk in them from the factory.
 
Shoot more powerful ammo. It's not the guns fault that you're shooting underloaded WWB.

.38 and 9mm have more variation in plinking ammo than any other caliber. That's usually why this happens. Try Blazer, Federal, American Eagle, and Corbon.
 
The Glock 42s had a stream of problems. Mine did - a total jammer. I wouldn't fool around with ammo choices, lubes, etc. - it should run with every commercial common load.

Call Glock, they will give you a shipping label and fix it. That's what I did and many others have.

That copper-colored gunk it to be left in place until it wears away. It facilitates the break-in. Take a new Glock and fire it. Add some light oil if you like, but do not clean off the copper-colored gunk.

I bought the first G42 my LGS received. I experienced lots of FTF and FTE with the pistol using multiple types of premium and range ammo. I sent the gun back to Glock and they replaced almost all of the internal parts. This, however, did not remedy the problems I experienced. So, I sent the gun back to Glock again. Glock replaced the pistol and the new G42 has worked flawlessly. They have great customer service. So, give them a call they will take care of you.
 
I have shot very few factory rounds in my 42 since I reload. This gun requires loads at near max. I have shot over 5000 rounds through mine and it's a joy to shoot. Once it wears in it will run fine. It does have a strong recoil spring. I left the slide locked back on mine in storage for the first 3 months. Don't know if that helped but mine is extremely reliable.
 
I will run some more ammo through it but I have soured on glock. Not happy at all. I was worried when I bought my first 1911 since I heard all about break in and no jhp. My Colt has been flawless from day 1. I bought the glock because I thought it would be flawless too since my 26 has been great. Boy was I wrong. If I can't this to run good after 400-500'rounds I will trade it in and take the loss. I'm not sending it back. I guess cheap ammo is the problem. What ammo is available in fmj that is hotter?

Why would they use such a stiff spring on a .380?

Because it's a Glock. Glocks are self defense pistols designed to run self defense ammo.
If you want to try to live with your G42 try parking in safe with the slide locked back. And ditch
the clp and put some oil on the rails and on the underside of the slide where the barrel locks up.

Also, does the chamber look like it was polished? I was surprised to see a polished chamber
when I got mine, new in the box. Never seen that in a Glock before.
 
I held off buying my 1st G42 because the early production were having problems, but as soon as someone on this board noticed that Glock had changed some of the integral parts I purchased one and it has been flawless with every brand of Ammo I have fed it.

I purchased a second G42 and it too is 100%.

In my experience, this is usually due to limp-wristing when it's a small gun like the Glock 42. I can't count the number of times a customer will come from our range with problems like you're having, and I'll go shoot their gun and I'll have zero stoppages.

I'm not saying this is definitely the problem, but it's certainly worth looking in to before you decide the problem is with the gun itself.

When someone has a good, solid grip, sometimes it can be difficult to limp-wrist a gun even if you're trying. I tried like heck to limp-wrist my Glock 19, and I finally managed it after lots and lots of trying by using a really wacky one-handed hold. But I've seen people who did it all time due to a very poor grip. Also, it's easier to do if you're using weaker ammo like Winchester White Box.

As for the Glock 42, just the other day a man came out of the range and said his 42 was having a failure to eject about every other round. So I went over to the range with his gun and a box of the same ammo he was using, and I didn't have a single stoppage for the whole 50 rounds.

I knew a woman that could get a Gen3 G19 to fail from limp wristing repeatedly. Once I showed her the proper grip the problem was solved.

Proper grip and ammo is key with little .380's and 9mm. The fact that this 42 runs fine with expensive defensive ammo is a pretty major clue!
 
Warm ammo required

I agree with wlkjr ~ just give it a little time with good ammo instead of WWB. My G42 is EDC in pocket & my daughter's HDW. Exceptionally reliable over several thousand rounds :cool:
 
One common problem is resting the left thumb (right handed) on the slide because the gun is so small. Just a little pressure will cause stovepipes. My son does this regularly.
When I reload for a particular gun, I will test shooting one handed with a soft grip and make sure the gun ejects and loads the next round. Then I usually bump up one more tenth of a grain.
 
I bought a Ruger P95 about a year ago, still in the box and basically unfired.
I had trouble with most brands of ammo till I stripped, cleaned and lightly oiled the piece. No problems since!!
 
Got mine last year after waiting till all the bugs were worked out at the factory . First mag mostly stove pipes , tried all the remedies mentioned but was disappointed as all my other Glocks run great right from the box . Talk to my LGS where I bought it , he in turn sent it back to Glock . Week and a half later I'm shooting a reliable , fun and easy conceal ( normal ) Glock . They switched out the parts they were having trouble with , polished the ramp and sent two more revised mags as well . Really ... Send it back for rework .
 
Don't have a lot of experience with Glock but I know my 42 likes a good shot of lube. Have solved similar problem on other guys Glocks with a good shot of oil for break in.

Glocks and dry slides seems to be an issue.
 
Check your ammo

TOURO,

I have had problems with WINCHESTER'S White Box ammo before. Check the ammo to see if it is the one with the FLAT TIP. This ammo can hang up on the feed ramp.

I have a GLOCK 42 and it has been wonderful. No problems, even with the WWB. However, I have had problems in other guns. The WWB .32ACP and .380ACP have been problematic in many different guns I have tried to use it in.

That includes COLT, SIG and WALTHER, so I am not talking about junk guns.

Yeah...you should clean and lube a new gun before shooting it.

New guns tend to be shipped with a rust preventative more so than a lubricant.
 
Lemon is always a possibility, even with Glock. That's why they have to earn my trust when new.

Honestly that Glock should shoot right out of the box as far as cleanliness, especially with a little lube. Not saying that's a good practice, but it should still function. If not, you have something amiss, especially in a problem prone model.
