1. Failure to fire

Failure to fire is a typical issue with the S&W 43C. It misfires several times. Sometimes, misfires result in no firing. In certain instances, it may have hit, but did not fire.

If there was a difficulty with tight case ejection or ejection rod, the hammer may have nicked the hammer shroud before contacting the pin.

The Fix:

Examine and thoroughly clean the ejector rod to resolve the issue. Repair the hammer. Replace the ammunition you’re using.

If the problem still happens after you change the ammunition, you should change the leaf spring. By changing the leaf spring, the power and force of the spring will increase, letting the hammer hit with more force.

Check the revolver’s leaf spring strain screw. If the tension screw is not tight enough, the firing pin may hit softly.

2. Heavy Trigger

There are problems with the trigger on the 43C. The trigger would become incredibly weighty.

The trigger press of 43C would typically rotate the cylinder but never drop the hammer.

The Fix:

It may be wise to examine the striker channel. Complete disassembly and lubrication will solve your problem.

3. Locked Cylinder

While shooting with a 43C, you may encounter a few complications, such as when you attempt to close the cylinder and it does not close completely. The cylinder may be compromised.

So, one possible explanation is that the cylinder couldn’t seal because the gas ring had broken and moved forward, getting stuck between the cylinder and the frame.

Maybe the extractor rod has become loose. If the crane of your S&W 43C is bent, the cylinder will not close and the gun will not lock up.

The Fix:

To fix the problem, tighten the extractor rod that may be loosened. You might want to change the cylinder. Fix the crane that is bent replace if needed.

4. Dirt on Forcing Cone

The top strap of the S&W 43C tends to get dirty quickly, especially where it meets the forcing cone.

Also, it was spitting a lot. The lead buildup is rather crazy for just having 70 mini magazines in the chamber.

The Fix:

Make use of Lewis Lead Remover by twisting the rubber stopper while the mesh eats away at the steel. Clean the area after soaking it and letting it sit for a while.

5. Light Primer Strikes

Another problem with the S&W 43C is that the priming often strikes too lightly. Misfires and hang fires are often the result of light priming strikes.

They still won’t happen every time, and not with every type of ammunition, but their frequency will increase.

An indication of a gun malfunction known as a “light strike,” which can happen repeatedly owing to mechanical defects or muck accumulation, is a far less pronounced depression on the suspect primer.

Ammunition failure occurs when a primer is not properly manufactured and therefore fails to fire when struck normally.

The Fix:

The repair may require cleaning, new springs, or new parts to replace old, broken ones. Professional assistance may be required for proper fit.

6. Ejection Issue

The S&W 43C’s ejector is faulty, and the gun may become so jammed that you are unable to fire it. To release shells from the ejector, you may need to tap it with a mallet.

This could be the result of using lower-pressure rounds, a defective production run, or a shoddy handload. The recoil spring is another typical root cause. An overly-tight recoil spring will cause the slide to cycle before the spent case is ejected from the gun.

The Fix:

Ensure that the weight of the recoil spring is appropriate for your ammunition. Lighter loads necessitate lighter springs, while heavier loads necessitate stiffer springs.

Additionally, you may need to replace your recoil spring if it is worn. Possible requirement to tighten the extractor. Field strip and inspect the firearm. If the extractor is excessively slack or appears worn, it may require tightening or replacement.
