Problems with Glock 48

4982 Views 39 Replies 26 Participants Last post by  gary357magnum
Hello all, I bought my first glock yesterday, a glock 48 to be exact. I took it out of the box, oiled it, and went to the range today. On nearly every round the slide was sluggish to go into battery,and I had two light primer strikes on federal hydrashok ammo. Has anyone else had problems with the 48? And since I cant return it what can I do to make it function properly? It's supposed to be my carry gun but my first impressions say dont trust it.

Hey everybody, thanks so much for the help, I took it back to the range today, i found my "sluggish" return to battery is the gun has trouble going into battery with the trigger in the fire position. After the trigger was released, it would limp forward. I read on another post some glock 48s trigger bar was cut too sharp and needed rounded out. Does anyone know about this? I'm new to glocks and not 100% sure how to look for this problem.
OP - thoughts and suggestion: Quite a few individuals are trying to help on this forum but sometimes it's difficult. It's always easier for someone with experience with glocks to look at the firearm in person. Suggestion: find someone with experience to take a look. If you can't find someone, mention what state you're in and maybe someone will send a PM and offer to take a look or steer you towards someone (if you're comfortable with this). OR back to Glock.

Just my 2 cents...….

PS - if you're in Wisconsin I'm happy to take a look...….
Yeah I see what you mean, it's kinda hard to diagnose over the internet, I'm gonna try a few more non invasive things and if that dosent work I've got an armorer lined up (sorry I'm nowhere near Wisconsin)

Just throwing some ideas out. Look down your mag well with a flashlight when reproducing the issue.

Is there any weird drag marks where the red parts meet?

Hand Trigger


The green thingy should push in smoothly and spring back smoothly. Spring under the thingy.

Yellow doohickey shouldn’t be dragging on your slide. It’s only job is to press the green thing when you pull the trigger.

Be careful using imprecise nomenclature like this on GT. We have a resident grammaton cleric who may be along shortly to admonish my poor terminology. Then again, he may not check out a thread that isn’t discussing a service weapon chambered in the ‘diminutive 9mm’ as he calls it.

You mean a serious defensive weapon, as opposed to a range toy.

Clean it, lube it (per glock manual). Then run couple hundred 124NATO through it.
Then come back and report how it did. If it failed, send it to the glock mothership.

I`ve had a few over the years that i sprayed dry-lube on the RSA, no issues afterwards.
Some guns are tight and need to be run hard until they free up a little bit from new out of the box.

I had some “performance issues” with my 48 right out of the box. It is bothersome since the 48 is possibly my favorite model - especially when considering Shield mags.

I do not clean new Glocks from the factory - I just take them out of the box and let them rip. I was *unpleasantly* surprised to have 3 malfunctions within the first 235 rounds. (All occurred with OEM mags) Two were FTEs and one FTF. I’ve had 360 rounds since with no further issues.

These were the first failures I recall ever in thousands of rounds through about 20 Glocks over the years.

I’m not sure what caused the problems. I also have a 43 that has a run flawless, so don’t think it is me. I have noticed that the 48 mag springs are very strong - so I’ve wondered if this might be part of things.

All in all, love my 48. I think it (when thinking of 9mm) is the “everything” Glock. Haven’t been enamored with the early issues and hoping it was just a fluke.

My 48 was flawless with factory ammo, new out of the box. However, failed to fire with my reloads using Winchester SP primers. There was a light primer strike mark on every round, and all failed to fire. Have some reloads with Remington SP 1 1/2 primers that I'll try and see if it's simply a matter of the primers I was using.

I experienced a similar thing (see my post). And agree. No problems with my 43 new out of the box with no disassembly or lubing before firing. Also the same with two 19's I have. The 48 is the only one that I've had FTF issues with thousands of rounds through my Glocks. Mine could have been a primer issue, but have found that Glocks eat everything with no problems, whether factory, my reloads, primers used and bullet weight.

My 48 has run very smoothly with just about any cheap 115 grain ammo that I feed it. I had one fail to feed on the 2nd magazine, then everything else has been great. No other hiccups. I was almost certainly riding the slide on my FTF. Being a new pistol, I had to get my grip worked out.

Was at the range today putting holes in 3 inch targets at 10 yards. Other than my “yips” the gun is more accurate than I am. And has been pleasantly reliable.

RSAs are cheap and is an easy thing to try. It may save a ton of money vs shipping off to Glock to have them looks at it to try that first.

Don't own a G48, but am a fan of the Winchester SP primer. Since it's considered a "soft" primer, anything in proper condition should fire it. For me, they are extremely reliable.

My 17L didn't like my reloads when I first got it brand new. Yes, i cleaned it before i shot it the first time. I had to put about 500 factory Blazer through it, before my reloads would work. Now it's 100% reliable with my reloads.
