What would happen?

[jaytothekizzay]

So when i carry a full magazine, +1 in the chamber. I manually load my +1 into the chamber with slide locked open. I then release the slide into battery. I then insert my full mag into the gun.

What would happen if i put my full mag into the gun by mistake, before i released the slide. Would the gun strip off another live round from the mag, causing the round to slam into the primer of my chambered +1 round?

Am I doing anything potentially dangerous?

What gun, that will make a difference.

I just tried that on my little Ruger LC9s and it locked the mag in place.

The way you are doing is not recommended. Yes, you will either get a double feed and have to clear it, or potenitally, the incoming round from the magazine could cause the round in the chamber to go off. Never heard of that happening, but anything striking a round in the chamber could have that effect.
As well, many guns do not recommend loading the chambered round manually. They are not designed for that.

The recommended way is to load your mag, insert and release the slide to chamber the round. Now your slide will be closed on a loaded firearm. Drop the partially loaded mag and load another round to full capacity and reinsert, or reload with another fully loaded mag.

Loading the chamber depends on the type of gun.

As example, it's not recommended to do this with a 1911 series pistol because the extractor is not designed to snap over a rim.
This "can" cause broken extractors or bent extractors.

Other guns with outside extractors like the Glock, S&W M&P, and other guns it's usually okay to drop a round in the chamber and drop the slide..... EXCEPT, I't may not be a good idea even with them because when the slide closes it drops with such force it "might" cause the gun to fire if the action is worn, dirty, or otherwise defective.
The slide closing on a loaded magazine slows and "pads" the force of the closing slide.

If you insert a round in the chamber, then insert a loaded mag and drop the slide, the gun will attempt to feed another round.
Potentially, the bullet nose could impact the primer of the round in the chamber and fire the round.

In order to do that, you'd have to be really absent minded and paying zero attention.

Best way to do it.... insert a loaded mag and chamber a round. Remove the mag and load another round into the mag.
Most police and military teach not to drop a round in the chamber first.

[Cheapshooter]

Not any more dangerous to you, but could be quite hazardous to your pistol. Sounds like a great way to break an extractor.
You are better off to insert a loaded mag, drop the slide to chamber a round, then remove the mag to top it off.

[Sevens]

You are quite potentially damaging your extractor actually and yes, it's not particularly "safe" gun handling to drop a slide or bolt on to a chambered round. Less so in a semiauto pistol more so in other platforms -- this can cause a slamfire.

If you wish to carry +1, strip a round from the magazine and then remove the mag and top it off.

[disseminator]

What they said.

[Sequins]

I always carry +1 in my ccw Glock 30.

My procedure is to ensure my weapon has no magazine inserted and a clear chamber, then I insert a fully loaded magazine and pull the slide back fully, then I release the slide clambering one round.

I now have a loaded pistol so I very carefully drop my magazine, set my gun down, load an additional round into the magazine returning it to full capacity, and then carefully pick my gun back up and insert the magazine a second time.

That gives me a full capacity magazine +1 round in the chamber and a tensioned striker ready to he released when I pull the trigger.

Thanks guys...will definately take your advice

Uh, don't do that. Unless the gun's manual explicitly says it's OK. Potential extractor damage.

Ditto to Sequins

[Deaf Smith]

Normally I use a empty mag and put one bullet in it, rack the slide with that mag in place. Then I insert a fully loaded magazine.

At least that is how I do it.

"...Would the gun strip off another live round..." Yep. That's how they work. Causes an instant jam, but isn't particularly dangerous. However, not paying attention to what you're doing is dangerous.

Don't do this. As said above, it's bad.

I've personally seen a heavily damaged extractor (HK external) from doing this.

Not only was the extractor so badly chipped that it barely caught the cartridge, the cartridge itself was mangled to the point it failed to fire.

Simply top off your magazine after using it to load the chamber in the same manner it will load the chamber when firing.

Just curiosity, but has anyone actually seen or seen a reliable report of a chambered round being fired by the impact of the second round bullet nose on the primer of the chambered round?

There were reports of that happening in bolt action rifles in the early years, leading to the adoption of "controlled feeding". It has not been mentioned much in recent years in spite of the common use of "push feed" (Remington 700, etc.), in part since the ammunition generally used in those rifles has been soft point, not military FMJ.

But I doubt that such a thing would happen in a handgun, where pointed bullets are uncommon, and the force of a slide moving under the pressure of the recoil spring would not have the impact of a bolt moving under manual operation.

The closest I've heard of was related to tube-loading repeaters like lever guns. Isn't that way they added plastic tips to some bullet types?

[Sevens]

I can't say that I have heard of the pointed tip of a bullet impacting a primer and resulting in a discharge.

However, to the original point of dropping/slamming a slide or a bolt on a chambered round... do this enough times with an AR-15 or other firearms with a floating firing pin and sooner or later you'll destroy a firearm and/or hurt someone.

[Mr. Hill]

That's an interesting question, James. Never heard of that happening with a 700. I wonder if the round coming out of the mag would bind up in the receiver before hitting the primer of the chambered round?

[HighValleyRanch]

Well, it may never have happened or been recorded as such, but I do believe in "MURPHY"S LAW!

[James K]

I have heard of it supposedly happening with a Remington 700 when the rifle was rebarrelled to other than the original caliber. Normally, the receiver is made to channel the round coming out of the magazine so the bullet point is away from the primer, but a differently shaped round (e.g., different shoulder angle) could change the angle of the round. It is easy to check; chamber a dummy round, but don't close the bolt enough for the extractor to catch. Then retract the bolt and feed another dummy round out of the magazine; the bullet point comes very close to the primer of the chambered round.

And it supposedly happened with the early push feed Mausers, causing Mauser to change the extractor and go to controlled feed.

While I never experienced this in the context of the OP's scenario, it's been my experience as well that the nose of the bullet doesn't hit where the primer is located on a chambered cartridge. I probably noticed this when trying to chamber a round with a stuck spent case than with a live round.

[Bill DeShivs]

Why do you think extractors have springs? They move-this is so they can slide over the rims of chambered rounds.
If this were not necessary, extractors would be fixed.
While it may not be a good idea to ride the extractor over the cartridge rim, it should not hurt the gun.

[arquebus357]

I've always wondered why extractors have that ramp shape at the tip.

Thanks Bill "again"

[Model12Win]

Quite frankly, "yer doin' it wrong".

Nobody I know does this. In fact it is widely known to be detrimental to some design such as the M1911A1.

Loading from the magazine will avoid any of these problems. You need to change your habits, that's all there is to it.

[Bill DeShivs]

In the 1911, the extractor is it's own spring. It's not a problem with a properly fitted extractor.
