The Quest for Reliability
One of many major issues for any handgun meant for self-defense is reliability. A malfunction in a crucial second can have severe penalties. Sadly, some customers have skilled reliability points with their S&W Defend 40s. Let’s discover among the commonest:
Feeding the Beast: When Issues Do not Load
Failure to feed (FTF) is likely one of the extra irritating issues. It occurs when a cartridge fails to advance from the journal and into the chamber, stopping the firearm from firing. A number of components can contribute to this:
Journal Issues
The journal itself is commonly the wrongdoer. Over time, journal springs can weaken, failing to exert sufficient stress to reliably push the cartridges upward. Harm to the feed lips – the steel edges on the prime of the journal that maintain the cartridges in place – may also trigger feeding issues. These lips would possibly change into bent or unfold, resulting in improper cartridge alignment. Furthermore, if the journal will not be designed for the ammunition getting used, feeding points can happen.
Ammunition’s Affect
The ammunition itself performs a major function. Sure bullet profiles and types could not feed easily within the Defend 40. For instance, some hollow-point bullets are recognized to be extra inclined to hold up than round-nose full steel jacket (FMJ) rounds. It’s important to conduct thorough testing with the particular ammunition you plan to hold.
Grip Strategies
The shooter’s grip can affect feeding. A grip that’s too unfastened, sometimes called “limp-wristing,” permits the firearm to maneuver excessively throughout recoil. This may disrupt the feeding cycle, because the slide could not cycle absolutely rearward, failing to select up the following cartridge.
Mechanical Concerns
Points with the extractor, the small steel half that pulls the spent casing from the chamber, or the feed ramp, the angled floor that guides the cartridge into the chamber, may also result in FTF. If the extractor does not correctly grasp the rim of the cartridge, it might’t pull the spherical into the chamber. Likewise, a tough or improperly angled feed ramp could cause rounds to snag as they’re fed.
Addressing FTF requires a scientific method. Journal upkeep is paramount. Examine magazines for injury and change worn or broken springs. Spend money on high quality magazines, ideally these made by S&W or a good aftermarket producer. Experiment with completely different ammunition sorts to search out what features greatest in your firearm. Apply a agency, constant grip to attenuate the results of recoil. Totally clear the feed ramp, and contemplate sprucing it if it seems tough. Examine the extractor for put on or injury, and contemplate an expert gunsmithing service.
When Extraction Goes Incorrect
Failure to extract (FTE) is one other crucial malfunction. This happens when the spent cartridge case stays caught within the chamber after firing, stopping the slide from absolutely biking and loading the following spherical.
Chamber Cleanliness
A grimy chamber is a frequent trigger. Powder residue and different particles can construct up, creating friction that stops the case from being pulled free. Common and meticulous cleansing of the chamber is important to stop this.
Extractor Inspection
The extractor itself can fail. It could break, chip, or put on down, shedding its capability to grip the cartridge rim firmly. The extractor spring, which gives the strain essential for the extractor to perform accurately, may also weaken or break, inflicting the extractor to lose its grip.
Ammunition High quality
The kind of ammunition used may also play a job. Weak or underpowered ammunition could not generate sufficient power to completely cycle the slide, resulting in a failure to extract.
To fight FTE, preserve the chamber meticulously clear. Examine the extractor and spring frequently, and change them in the event that they present indicators of wear and tear or injury. Use high-quality ammunition with ample energy to reliably cycle the slide.
Ejection Difficulties: The Cartridge That Will not Depart
Failure to eject (FTEj) is said to FTE, in that the spent casing does not go away the firearm because it ought to. The case could get caught within the ejection port, or solely partially eject, inflicting a jam.
Extractor and Ejector
Issues with the extractor that have been talked about earlier could cause this. If the extractor does not have a great maintain on the case, ejection could also be affected. As well as, if the ejector (one other small half that helps throw the spent casing from the firearm) is broken or malfunctioning, FTEj is feasible. Moreover, particles within the chamber could cause the identical sorts of issues.
Troubleshooting includes a examine of the extractor, and a take a look at the ejector. It is a good suggestion to have a gunsmith examine and maybe change these elements, in addition to ensuring to maintain the chamber as clear as doable.
Slide Lock Frustrations
Though much less widespread, some Defend 40 house owners have encountered slide lock points. On this situation, the slide could fail to lock again after the final spherical is fired, or it could lock again prematurely.
Grip and Lever Interplay
One doable trigger is the shooter’s grip interfering with the slide lock lever. Some shooters inadvertently bump the lever throughout firing, stopping it from participating the slide. Ensure that your grip is correct, with out touching the lever.
Lever Integrity
A faulty slide lock lever may also trigger this difficulty. If the lever is broken or worn, it could not perform accurately. Examine and contemplate a lever alternative if there’s a drawback.

Aftermarket grips, typically produced from textured rubber or different supplies, are an alternative choice. These can considerably enhance the grip’s really feel and provide a greater grip, particularly in moist situations.
Set off Troubles
The Defend 40’s set off pull traits may also have an effect on the taking pictures expertise. The set off pull is commonly described as having a average weight and a comparatively lengthy journey distance.
Some shooters discover the set off pull to be lower than excellent. It is typically not a “crisp” set off pull in comparison with different firearms.
Aftermarket set off upgrades can be found for the Defend 40. These triggers can shorten the set off journey, cut back the set off pull weight, and enhance the general really feel of the set off, probably bettering accuracy and taking pictures enjoyment.
