Glock slide question

Recommended Posts

Was able to finally shot the glock 19 gen4 ipicked up a few months back. Great time, handles beautifully.

 

Now my questions. It took a good amount of force to place the mag into the gun. Is that normal? Also, if the slide was back when I loaded the mag, it (the slide)would release and slide forward chambering a round. Is this normal??This gun had 0 rounds through it before me, so I dont know if that is partof the issue. Im a newbie to pistols, but I feel that this should not be happening?

Yes, if your mag is full it is harder to push in. If you leave one round out, it goes in much easier. That is because the spring is completely compressed when full, thus making it harder.

 

If the slide is open and you insert a new mag, it should not close by itself. You should need to either press the slide release or rack the slide. I do not believe that it should close automatically. At least that is how it is on my G21.

You can "auto-forward" the slide on any semi-auto pistol if you insert the mag the right way, although it is much easier with a Glock. It is common and not an issue with the gun.

 

I know some shooters that like that "feature" and train to do it all the time.

 

Personally I don't. I like to know that the mag is fully seated before sending the slide home. It may take a fraction of a second longer to complete my reload, but I have seen the slide go home before the mag is seated loading an empty chamber and would rather avoid that. That fraction of a second will seem lightning fast compared to a multisecond malfunction drill when you try to fire an empty chamber

I have never had a problem seating fully loaded Glock mags new or otherwise regardless if the slide was forward or not.

 

Be aggressive - go flat to flat (flat back of mag to the flat rear of magwell) and and send that mag home with a single firm push.

 

Do not seat the mag in the magwell and then slap the bottom of the mag.

Just tried this with my Glock 22 Gen 3, using a new mag. Mine did not drop the slide even after smacking it on the baseplate multiple times.

You are going to need to try it with a loaded mag (use snap caps or empty brass if you are not at the range). It won't work with an empty mag because of the built in slide lock feature.

 

Hold the gun with a 45 degree muzzle up and when you insert the mag you need to hit where the grip plug fills in the hollow at the bottom of the grip. You may need to hit it fairly hard, but it will go.

Guys, we are talking about a brand new Glock. 0 down the pipe. Send the Glock in to the factory to be checked out. Your pistol should not be doing this. Period.

 

If you are new to pistols I'm sure you're pulling off a high speed tactical operator "auto foward", haha. Which I don't suggest for anyone to practice, because it just isn't practical in anyway. Exeptions being 3 gun, uspsa, etc. But Exposure said, rack the slide.

 

As for the mag being tight, its a glock just ram that b!tch in there! 1 in the chamber and 15 in the mag. If you are storing long term, yeah 14 to save the spring a bit. However, the spring steal is pretty tough.

 

Was able to finally shot the glock 19 gen4 ipicked up a few months back. Great time, handles beautifully.

If the OP sends his pistol back for this he is just wasting money. It is 100% normal and happens because of inertia.

 

When you smack the bottom of the pistol at the correct angle when seating a loaded mag 2 things happen simultaneously: 1) The slide moves to the rear a fraction of an inch. This takes pressure off the slide lock lever and 2) Once the tension is off the slide lock, the spring that keeps the slide lock down against the frame and prevents it from locking the slide back on every shot does its job and pulls the slide lock lever down allowing the slide to go home. The only way to prevent this from an engineering standpoint is to lighten the slide so much that there is not enough mass for inertia to work on it or change the strength of the recoil spring to be so strong that the slide won't move to the rear when the pistol is hit.

 

The other way to prevent it is to seat the mags squarely from the bottom and avoid hitting the grip at an angle from the rear when loading.

 

As far as downloading to save the springs or relax the springs is a myth. Modern springs lose their "strength" by cycling. Keeping a mag fully loaded, partially loaded, or completely empty makes no difference. Cycles of loading and then unloading are what weakens springs over time. Unless you move a spring past its elastic limit - either by over-compressing or stretching - you have nothing to worry about when leaving a mag fully loaded, a hammer cocked, or a slide locked to the rear.

You can also hit it at a 45 degree angle to replicate pressing where the lanyard gap meets the magazine.

You are not telling me anything I don't know.

 

The OP is new to pistols. He's not pulling off an auto foward.

 

Glock has charged you to fix your pistol? What have you done to piss them off?

I guarantee he is "auto forwarding". I see brand new shooters that have never touched a gun in there lives make Glocks auto forward all the time. It isn't some super secret high-speed deltaninjasealranger trick that anyone need to be taught. They are trying so had to seat that mag that they slap the pistol so sharply the slide goes home. Look at what he wrote, he starts by saying that the mags are hard to seat, so you know he is hitting the crap out of the bottom of the mag.

 

I see ot so often that sometimes I think it is harder to teach my new shooters how not to do it than it would be to show them how.

 

I have never had to send a Glock back. I assume you pay the shipping costs at least one way. If you ship them a pistol and they find nothing wrong with it does the warranty still cover their time, labor, and effort?

I knew it had to be with a full mag.

 

Tried it again and it worked. Slide went into battery, with a full mag (snap caps). I repeated the test several times to make sure I wasn't hitting the slide release with my thumb when I smacked it.

 

I guess I didn't hit it hard enough last night to make it work, although I've NEVER had to use ANY force to load a full mag into my G22.

Trying to figure out why the OP is having to force his mag into the magwell.

Maybe it's inexperience with the pistol, maybe I'm missing something reading his post.

I don't think he means it won't fit in the magwell or that he is having a hard sliding it through the magwell. I think he means he has to really push it hard to get it to seat or "click" in who the mag catch holds it. I have seen that with brand new Glock mags loaded all the way up.

Now that is pretty funny.

 

No, Glock's customer service rocks. Free return labels and free shipping back.

Why do I recommend against slapping the mag to seat it?

 

I have seen a lot of people not fully seat the mag in the initial insertion. Then if holding the weapon so the barrel is perpendicular to the deck, (or in any orientation where gravity can "pull" on the loaded mag) when you take your hand away from the mag and flatten it out to palm strike the baseplate in order to seat it and get that *click*, gravity can overcome the friction between the magwell and the loaded mag and the mag can fall right out of the pistol. I see it a lot. Doing this while moving can make this happen even easier. I can think of few things worse to do in a gunfight than trying to bend over and pick up a mag of the ground.

 

It is also wasted movement and ineffecient, slowing you down when you need to be fast. All you need is a single hard, aggressive "push" into the magwell to seat the mag whether you are doing a speed reload from slide lock or a tactical reload or reload with retention to top off your pistol with a round still in the chamber and then get back to doing what you need to do. No time should be wasted with slapping, hitting, tapping, etc..

 

ETA: Just saw you have a G27. That is a hard pistol to do this when as you aggressively push that mag in, the palm of your shooting hand is in the way. You have the potential to either pinch the crap out of your palm or your hand may prevent you from getting the mag in far enought to seat on the first try. If you relax the bottom of your grip (pinky, ring finger, and palm) but keep hold of the pistol with the top of your hand (trigger finger, middle finger and thumb) when you do this, while moving the bottom if your palm away from the pistol grip a fraction of an inch it can alleviate the issue. With a little practice it is simple and becomes second nature and very fast.

Ok, thanks for the reply.

It's a non-issue with the slide locked, as there is no tension on the mag spring...it's only when the slide is forward where you have to overcome the load from the mag spring. 

And yes, if you're not careful, you will pinch the crap outta your right palm, lol.

and a blood blister that lasts for a week.. Ouch..

Like I say, I've never had issue seating a full mag in my G22 ever, even when new. Mine is an older Gen 3 purchased early 2000.

Possibly they redesigned the mag catch or the mags since then.

FYI - My G27 Gen 4 has the same issue as the OP. You have to force it the last 1/16"-1/8" to get the mag to catch with a full one.

 

 

Hijack for those that may know.....

 

I recently purchased a 15 round mag, and I have reversed my mag catch. IIRC, the Gen 4 mags have metal in the catch locations on both sides...but the 15 rounder doesn't. Do I have a problem? It seems to catch and function just fine, but haven't used it that much.
