Is this legit? Seems violent, and I wasn't picking up the casings to see if they were damaged, but yesterday at the range I was trying to minimize my time between magazines and this method seemed the best.

To be clear: If you simply insert the magazine until it seats it won't shut the slide, but if you insert it until it has an inch left and then seat it with your palm quickly it will.

Is this something folks are taught not to do in defense/shooting classes, or is it copacetic?

My wife showed me this after one of her departments range days. Says one of the trainers was showing them this.

I just shook my head. Its not 100% reliable and repeatable.

"I" will never use this method....ever.

It really only works on certain brands as well. Mostly on glocks, did not work at all on the Springfield XD she used to carry.

I hear it works better if you hold the gun sideways too.

So you'd press up on the slide release lever to prevent it, seat the mag, then flip the lever down? Or just not be so spirited with inserting the slide? That seems hard to control.

This.

It sometimes works. "Sometimes" is a poor foundation for SD.

Sounds like a great way to jack up feed lips or cause a bad misfeed. Which means whatever few seconds saved just got wasted.

Are you talking about on a rifle, AR, or a handgun? I mean on a handgun I close the slide with my thumb autonomously basically, it requires literally 0 extra time for me to insert the mag, re aim, and rack the slide with my thumb on the way to aiming.

As said, I have to assume this is with lower end weapons as their machining and specs is looser giving you more room for movement.

It's a pistol. The manual says:

I figured it was just the mass of loaded mag going in causing this catch to slip since the weight of that lever wants to stay in place...

But it doesn't work if the mag isn't loaded, so that theory fails.

IDK, if it's not smart I won't do it. I know there are much more knowledgable people here when it comes to pistol defense than I am...and that's the reason I posted.

I was taught there isn't a down side to it, if you can master it. I have a hard time doing it with my glocks but my all steel guns seem to do it with ease.

When I was trying it. Sometimes id have to hold the mag and almost hit it to get it to work. Other times I could get with a really forceful push.

Either way it wasnt natural and required me to focus on loading a mag rather than focus on a target or moving.

There is a huge downside when a couple rounds pop out the mag and cause a double feed or giant clusterfrick. Obviously, the mag should probably have been tossed before that, but still its an issue when hitting a magazine.

my CC instructor, a cop, had us practice doing this. unless you're a cop or a competition shooter i don't know why you would spend time practicing this.

I shoot a Glock almost exclusively and doing a mag change and getting back on target is pretty damn easy without doing this. I have never paid any attention to the amount of force im using when inserting a mag but have never had the slide close on it own.


I also rarely ever shoot a mag till empty. Count your rounds and do a mag change before empty. That way you keep a loaded weapon down range on target while putting in a fresh one

Brah. Never seen John Wick?

You need to be counting your rounds. Drop the mag after the last round is auto fed, before you fire it, insert a full mag. Slide never needs to lock.

With my M9 I have to make a conscious effort to not do this. Seems like it slams shut more often than not.

There are a lot of things, that are far more important, that your instructor could have spent that time on.

I don't know of any cops or competition shooters that practice this technique, nor do I know of a single prominent SD trainer who teaches this.

If the slide happens to close when you insert the mag -- fine. Start shooting.

If it doesn't close -- fine. Just close it manually and start shooting.

This guy is correct. It all depends on the weapon. Pistols will break down quickly when TPOS uses this method,

I went to Glock School and they said that this is a result of a town slide stop lever. They recommend replacing it when this starts happening.

My Gen 3 duty weapon did it easily. My Gen 4 did not.

My HK has less than 1k rounds through it, I doubt anything is worn. And I'll try to keep it that way by not jamming the mag in.

If you could close the slide like this, would it not be prone to close on its own after the last round was fired? I mean the force after a round is fired is much greater than closing the slide?
