Glock 30 Jamming ?

Just came across a G30 used, had some wear from carrying but looked good. I gave it a quick cleaning and had at it. The last 45 ACP I shot was my 1911 that I sold a few years back.
OK this thing at about 30' is dead on, no kidding I was surprised 2" in groups. Now the BUT, I was shooting reloads from 7 years ago and everyone of the 30 or so jammed either on the way in (one round wouldn't extract and the other was right behind) or out (brass flipped up but didn't clear and the next round was trying to seat). Here is what I was shooting.185g JHP, 5g Bullseye Lg PP and OAL 1.230. Need some help here? I put thousands of these thru my 1911 and never had one problem.
One last thing when there is a round in the mag I have to force the mag in. With no round mag goes in easy.

OK I did last night while sitting here take this thing down to the bones. It was the filthiest gun I ever seen. Both the FP hole as well as the extractor spring/rod and hole were plugged with dirt and gummed up.
It's still to cold her 19 degrees to go check it out could this have been the problem you think?

IMO......a good cleaning always helps but my 30sf mags are still tuff to get in after almost 8mos.....I just don't know about these Glock mags. The obvious question is have you fired commercial hardball out of her yet....if so how did that go....? My 1911's are a much looser fit-up than this Glock of mine and my older 1911's will eat anything that I feed them.

Since it's still cold here I may do this. I haven't bought factory ammo in a long time I feel sticker shock coming. My 1911 had never jammed and I shot all kinds of loads even ones I screwed up, to long to short a little to much powder and little to little. It just shot anything.
My point is I want this to be my carry weapon and am hoping it will be reliable!

My 30SF had one of the extremely rare (for me, rare) Glock "Failures" of failing to go fully into battery a high percentage of the time. The problem was the raised tab that pushes on the firing pin safety was rubbing on the slide.

Glock replaced the original "4256-1" trigger bar with a "4256-1-" and that pretty much fixed the problem. But if you looked closely you could still see a scratch on the riser part. There are threads all over the web on this exact problem.

What I did after Glock put in the "-1-" trigger bar was buzz the scratch away with my Dremel tool and then polish the area with 600 grit emery cloth. After that, it's been perfect through a couple of thousand rounds or so.

My 185 grain Winchester JHP load functions best with and OAL of 1.190" - 1.200". I also like 5.0 grains Bullseye with my 230 grain Lee TC/TL.

I have had people want to argue about the existence of the 4256-1- trigger bar. Here's a pic.

If I picked up a used handgun...not LNIB...I always replace the recoil spring at a minimum. Next is a deep cleaning....mags included. A working load doesn't always work perfectly for every gun you own chambered in that caliber.

OK this is getting old.
Went out today and shot 9 shots with NP again amazed at the accuracy. Then the second magazine and out of nine only two fired the others have a much lighter strike in the primer. My thinking as dirty as the hole where the firing pin goes was so dirty maybe there is some dirt is still in it. Back to cleaning.
The gentleman I bought this from swears he didn't put but 750 rounds thru it and never had a misfire.
Oh and my trigger bar only has 4251, nothing else.

It didn't get that filthy for no reason. Sounds like the previous owner had a lot of fun with that gun and only sold it when it started jamming. It takes a heck of a lot of shooting to get a Glock plugged with fouling like that, and I don't see him doing that much shooting while clearing nonstop malfunctions.

My guess is cleaning and/or replacing the recoil and extractor spring will get it back to working order. Consider yourself lucky to have acquired a great gun from someone who couldn't be bothered with the 5 minutes it takes to breakdown and clean a Glock and/or replace normal serviceable parts.

OK now no fire at all. All light hits. Any suggestions? :banghead: I think this person had a lot more then 750 thru this thing and had no idea about cleaning. Anyway it's mine now so I would never sell something that don't work.

Find a thin screwdriver that fits down the firing pin channel and scrape the hardened crud out that collects against the front of that channel. If that doesn't do it have a look at the striker spring and replace it.

Just for S&G, find a pencil with eraser. Unloaded, drop the pencil eraser down into the barrel, pointing at the ceiling. Pull trigger...if it barely comes out you definitely have a firing pin issue.

A few things come to mind:

Reloads from SEVEN years ago? Pull the bullets, dump the powder, RESIZE and reprime the cases. I've had old reloads go bad. Blooper loads, I could actually see the rounds going downrange. An old gunsmith told me that sometimes brass that's been reloaded a few times (work hardened) will, over the years, 'relax' its grip on the bullet, allowing moisture (humidity) to weaken the powder and/or primer. This could also explain the failures to chamber.

If you don't know how, get someone to take the slide down and clean the firing pin channel and have a look at the plastic liner. Solvent or oil and just plain crud could be slowing the striker down enough for the light strikes. Put in a new spring while you're in there. It takes a lot to crud up a Glock, but it can be done.

Also, the G30 recoil spring is pretty stout and softball loads might not work well. Try some full power loads.

I would try some high quality production ammo first... then if that isnt the issue..

+1 for cleaning the firing pin channel. A a lot of people think the little hole in the slide is for oil. It's actually to let the crud out. Get some one to detail strip it for you. it's not hard. You might want to google "Glock function check" for starters. I would advise sticking with factory ammo until you get this sorted out just to eliminate that as a culprit. Good luck.

I think VA27 is on to something here. The Glock factory recoil spring is 17 pounds. I use 185 Berry's plated bullets at 4.9 of Bullseye and wouldn't go a grain lower. They do shoot well and are a light recoiling load, but they also just lay the brass a few steps away. Try to bump the loads up just a little till you get the heavy recoil spring figured out.

Either way I am a clean freak about my guns so I already ordered new springs and sleeves, kind of inexpensive. Also wanted the extended stop lever and slide lock. I want this thing to work and work well, it fits great and is very accurate.
I did take it down again last night and finally put a bright light down the slide hole and it still was dirty, I let some #9 soak and got out a few small flakes. I am off to church and will find some factory leads. I know not all guns are alike but I only had one other firearm not fire and that was my rifle and attributed that to the primer. But these 45ACP loads have worked 100% in my 1911. I'll update later and thanks all.

OK got warmer here today so we went into the hole for some shooting. Bought some no name ammo at Wally World (the only stuff they had, gentleman said they get a delivery every day and it's gone by noon?) and went thru 50 rounds perfect, even laid the Brass in a nice little pile for me. Sent thru a bunch of reloads NP.
I am convinced there was still crud in the firing pin channel.:mad:
:):)Thanks all!!!!!!!!!!!!!!!!!!!!!!!!:)
