Auto-Forward Ruger Security 9?!?!?

[LoonWulf]

Ive had my 10mm do it a couple times, As far as i remember it was that particular mag not shoving the slide stop up far enough. It never did it with the other mag I had......I'll ask my buddy if the gun he got from me with that mag ever does it.
Ive never cared, if theres rounds going in the gun with the slide back, theres a round going in the chamber.

Most self-loading handguns do not have a slide release, only a slide stop. Read the manuals and notice the part name. They want you to slingshot the gun. Mostly.

Semantically you're correct.

Perhaps way to more clearly state my point would have been to say that the P7 does not have a lever/button/switch attached to the slide stop that can be used to release the slide

Slovakian Grand Power pistols do this constantly even when the magazine is inserted without particular force. I believe they are designed that way. Graham Baates of GBguns youtube channel is a big fan of these Slovakian pistols (as I am too) and in every video shooting he shows this characteristic. I also use this feature with my Grand Power Q100 to chamber the first round from the hold open position; no sling shot, no hold open lever, just insert the loaded magazine with enough force.

Some guns do, some don't. The ones that do, don't always do it. It ain't a problem.

This sounds like a quality control/wear issue. The slide probably should probably not autoforward when inserting a magazine with a normal amount of force when the pistol is new. But as the slide catch and the corresponding contact point on the slide wears, it will be easier to make the slide autoforward when vigorously inserting the magazine. If you use the slide catch to release the slide, it will cause wear on the slide catch and the contact point on the slide. If the slide catch and contact point on the slide wear sufficiently the slide catch may not lock back the slide at all.

When my P365XL was new the slide catch would NOT release by itself when the slide was retracted. I had to manually pull the slide catch downward while retracting the slide in order to get the slide catch to release the slide. This is a quality control issue. Sig's quality control isn't perfect and they expect YOU to complete the finishing work by using the pistol to wear-in the parts.

When I am reinstalling the slide onto the FCU of my P365 the takedown lever will sometimes auto-rotate into the normal position. When I have reinstalled the slide and locked it back, when I rotate the takedown lever into it's normal position it sometimes releases the slide. My P365 did not act this way when it was new. I just developed the habit of keeping my thumb on the takedown lever while I am reinstalling the slide, and then while I am still holding the slide rearward I push upward on the slide catch. Then I rotate the takedown lever into the normal position, and then retract the slide enough for the slide catch to release and release the slide.

With a simple slide catch design, such as that used on my P365, you can probably design it so that slamming the magazine into the pistol will not autorelease the slide. But then the slide catch would probably not autorelease when you retract the slide completely, and you would likely need to manually pull the slide catch downward.

If the autoforwarding slide bothers you it might be worth it to replace the slide catch to see if it will cure the problem.

You might also try pushing the slide catch upward with your thumb while inserting a magazine. Whether you can even do this will depend upon the slide catch position and your particular thumb size and length.

Most self-loading handguns do not have a slide release, only a slide stop. Read the manuals and notice the part name. They want you to slingshot the gun. Mostly.

Some firearms companies place less significance on specific words than you do. Below are extracts from two manuals, one uses slide catch and says to use it to release the slide and the other uses slide release but says to slingshot to release the slide.

Beretta 92A1 manual:
page 20: "If the slide is blocked in the open position by the slide catch or by an empty magazine inserted in the pistol, press the slide catch downward to close the slide."
page 28: "Press the slide catch to close the slide (Fig. 30)."

H&K P30L manual:
page 20: "Chamber a cartridge by depressing the slide release or by pulling the slide fully to the rear and releasing it."
page 21: "Pull slide back completely and let it snap forwards."

It's not unusual for a company to misuse a word. In this case I believe that the term "slide catch" most accurately describes it's purpose and what it does. A slide release would more accurately describe a part that disengages the slide catch. In the case of a simple slide catch design there is no additional part to cause the slide to release. The slide catch automatically releases when the force of the recoil spring is removed by fully retracting the slide. Perhaps the slide catch return spring could be considered the slide catch release.

Whether or not it is a good idea to use the slide catch to release the slide is a matter of debate. Using the slide catch to release the slide can slightly reduce the time to reload and get back on target. But doing so will cause the slide catch and the place on the slide where it contacts to wear faster. But some people will just consider the slide catch to be a consumable part that needs periodic replacement. Some people may believe that it is more reliable to retract the slide to release it. If you only have one hand available (You may be fending off your attacker with one hand while you are reloading.) using the slide catch may be your only option. It's a tradeoff.

A lot of guns will do this, whether it's considered a feature or not

It's one of those "problems" found by newer shooters, along with "false resets" and desperate need for "upgrades"

The recoil spring is pushing slide forward, the slide stop spring is pushing stop down--but can't overcome the pressure
applied by the recoil spring.

Add impulse of slapping a magazine--the slide momentarily compresses recoil spring, taking pressure off the slide stop,
which drops under influence of it's spring. Now unrestrained, slide goes forward. No defect, no mystery.

 

[Jim Watson]

In 1902 Colt called it a "slide stop" and instructed you to depress it when reloading.
In the 1910 patent leading to the M1911, we first have the "pivot pin" with a "handle" and a protruding lug so that it may be moved up or down at will.
But the next paragraph starts referring to it as a "slide-stop" and explaining how it differs from the 1902 device.

I read a similar post about the Security 9 anomaly on the other Ruger forum months ago. The pistol owner contacted Ruger which said that it is not a designed feature, but that it happened with some of the Sec 9 pistols. Ruger also said it was perfectly safe to shoot. Yet, the owner did not get an explanation of what caused the anomaly. My guess is that it is caused by some magazines that might have tolerance differences.

I cleaned a sec 9 for a friend. It uses tiny roll pins & tension springs. No thanks.

I used to have a Security 9c. If I recall, the slide lock was not meant to be a slide release, per the manual. The manual went with the gun when I sold it, so I may be mistaken, but It stated that you need to slingshot the slide to chamber a round, one of the reasons I didn't like it. It would auto forward if the magazine was slammed in. That was not in the manual.

Security 9 manual, page 13

The slide stop is spring loaded. Therefore, when there is a loaded magazine in place and the slide is being held open by the slide stop, if the pistol is jarred, the slide can fly forward and chamber a cartridge.

If a person does use the slide lock/catch to release the slide, it will cause wear on the slide lock/catch, and on the corresponding portion of the slide, and that will make the slide more prone to releasing when you give the magazine a whack while you are inserting it.

So it's a tradeoff between wear and being able to release the slide slightly more quickly. Personally I don't think that it makes enough difference in time to matter, so I will slingshot the slide unless my left hand is in use defending myself or otherwise incapacitated. YMMV.

This…….

I’ve shot USPSA for years and most people with DA/SA guns tune the slide stop to achieve this function consistently, desirable for faster reloads if you Inadvertently shoot to slide lock. Guys in IDPA will shoot to slide lock, so very desirable function for quicker reloads. All of my CZ’s do it and it’s VERY controllable depending on how aggressively you seat the mag.

 

[Bcwitt]

I disassembled a security 9. The construction is very questionable. Tiny roll pins & major functions w very small tension springs. Its a super cheap gun, not to be taken seriously, IMO.

Page 15 of the H&K USP operator's manual mentions this and it's normal:

"Forcefully inserting a loaded magazine into the USP Pistol may cause
the pistols slide to close, chambering a cartridge and making the USP ready to fire."
