Light primer strikeInstall a heavy striker spring
Ejection problemTry changing ammo and magazine/ do basic maneuver
Jamming problemReplace extractor, magazine/ send to Ruger
Trigger issueSend to Ruger
Cycle problemDo not miss regular maintenance schedule

1. Light Primer Strike:

The gun won’t fire if the firing pin strike on the primer is light.

Possible Reasons

When struck with enough force from the firing pin or electrically fired, primers react chemically to produce heat, which is passed to the primary propellant charge and ignites it, propelling the projectile.

But for some reason, if the firing pin fails to hit with enough force then the primer’s chemical reaction won’t start. As a result, the round won’t go off. In short, firing a pin with a weak striker spring causes this problem. 

The Fix:

The fix is really simple as all you have to do is install a heavy striker spring. Hopefully, the heavy spring will be able to deliver enough force to the firing pin to properly hit the primer.

If changing the spring does not work, then there could be a design flaw. In that case, you will have to consult a gunsmith or send the gun to Ruger.

2. Ejection Problem:

The fired case is expelled from the chamber but not completely, causing the slide to lock partly open on the empty case.

Possible Reasons

Failures to eject can be caused by a filthy gun or a rusted chamber, as well as the shooter’s lack of a solid grip.

The most typical cause of this issue is “riding the slide,” which is when you hang on to the slide as it moves forward, limiting its forward speed.

The case is often caught by the slide and kept upright, the empty hull pointing upwards like the metal chimney of a stove, giving rise to the moniker “stovepiping.”

The Fix:

Pull the slide all the way to the rear on all semi-automatics and let it go. To correctly lodge the bullet in the chamber, the slide must move quickly, even violently, to the forward position.

To begin, tap the magazine to verify that it is completely seated. Then, gently twist the pistol so that the ejection port is at an angle to the ground, and rack the slide forcefully.

This should eject the expended cartridge and allow a new cartridge to enter the chamber.

3. Jamming Problem:

There are several reasons why firearms jam. Gun jams are frequently referred to as gun malfunctions.

Possible Reasons

A variety of factors might contribute to a traffic bottleneck. The weapon’s poor construction can lead pieces to stick or snag on one another.

Poor maintenance generates excessive buildup and might cause components to stick.

Cheap ammo can hasten this process or even leave behind bits that can become lodged in moving components and cause the weapon to bind.

The Fix:

The most prevalent causes of firearm jams include ammunition, magazines, and extractors. Experiment with changing them and shooting in different combinations.

If this does not cure the problem, it is most likely a design flaw, in which case you should contact the manufacturer.

4. Trigger Issue:

When you let go of the trigger after holding it, you should hear an audible click when it resets. It might have some burrs that need to be cleaned out.

Possible Reasons

Trigger reset, also known as riding the reset, is the point after a shot when the trigger and sear are re-engaged within the firing mechanism, allowing you to shoot again.

Mechanisms involving triggers are the most complex mechanisms in today’s guns. So, any internal component failure can cause the problem.

The Fix:

I would recommend sending the gun to Ruger to take a look right away. You should refrain from any urge to disassemble if you don’t have the necessary skills.

If you are in a hurry, then seeing an experienced gunsmith would also be a good option to pinpoint and fix the problem.

5. Cycle Problems:

Between the discharge of one shot and the time at which the next shot is ready to be fired, a complete cycle of these actions must occur.

Possible Reasons

A gun may jam due to defective ammo or a magazine that has been dumped on concrete. Guns do require maintenance and, sometimes, the replacement of an extractor, firing pin, or other parts.

Some weapons are more prone to have cycling problems than others, or they may be extremely sensitive to a specific loading, and unfortunately, the SR40 is one of them.

The Fix:

Make sure the magazine is not causing the issue as it tends to be the culprit most of the time. Always replace the firing pin, extractor, hammer, and other parts then they wear out.

Do not expose the gun to its cold climate all of a sudden as it will cause condensation. So first, let it come down to room temperature and then bring it out.

User Feedback on Ruger SR40

The Ruger SR40 is a follow-up to the popular Ruger SR9 in Ruger’s SR family of pistols.

An empty magazine weighs around 27 ounces. While it is well-equipped with safety mechanisms, it becomes slightly uncomfortable for the thumb after a few hundred rounds. When the cartridge is put in the chamber, the flat-loaded chamber sticks up, making the handgun safe to use.

The Ruger SR40 also stands out for its innovative link-less method for locking and unlocking the barrel, which is an advance over other pistols in the Ruger P-series. Furthermore, the slide’s rapid and easy fore and aft movement makes its use quite convenient for an inexperienced owner.

I’d like to see a set of night sights on the gun, which is an easy fix. It might be asking for too much, but I still prefer a little bit lighter, smoother trigger on a defense pistol
