1. Titanium Cylinder Erosion:
Due to the titanium cylinder of this firearm, some buyers are reluctant to purchase it. Because wrong bullet use might cause the cylinder to deteriorate. The use of light bullets (less than 120 grain) will cause the cylinder to wear.
The problem with these light bullets is their length, which is related to their weight. The cylinder may erode if you apply anything abrasive to it.
Never load any powder faster than Unique to avoid this problem. You can attempt to prevent this corrosion by using a decent Unique load of 140 grain Silvertips.
You can swap out your existing bullets for shorter ones because shorter bullets leave the case mouth earlier when pressures and temperatures are at their highest.
Keep in mind that after the cylinder began to degrade, you should never shoot a gun. because there’s a chance the gun will catch fire.
2. Difficult Extraction:
While using the revolver, you may well have difficult extraction. Occasionally, a strong extraction might cause the brass inside the cylinder to crack.
The cylinder may not be hitting the frame properly, or the yoke retention screw may be damaged or too tight, which is cutting the bullets.
Sometimes there is not enough pressure applied to the center extractor pin, which results in this.
Check if the extractor’s central pin is in the proper position. Also, remember to examine the yoke retention pin; if it is broken, replace it as soon as you can.
It’s a major problem, so if you can’t fix it yourself, call a professional or send it to the manufacturer for repair.
3. Cylinder Jamming:
While shooting the 357 Magnums, the cylinder seems to lock up.
It locks up when you try to get the cylinder out of the slot. You might need to apply pressure to unlock the cylinder. If the ejector rod is not tightened, this happens frequently.
Inspect the ejector rod of your Smith and Wesson 340PD. If it is loose, you have to tighten it.
Open the cylinder to inspect the rod properly. If you cannot tighten it yourself, take the gun to a gunsmith.
4. Ammo Stuck in the Chambers:
Firing the 357 Magnum ammo on the Smith and Wesson 340PD may seem normal but while getting the ammo casings out of the chambers, you might have trouble.
The casings seem to get stuck inside the cylinder chambers. This happens due to fouling in the chamber for using the 357 Magnum cartridges.
If the chambers of the cylinder are dirty, this problem occurs.
Since the problem occurs with a dirty gun, you have to keep it clean. An unclean gun will have a buildup of gunpowder and lead inside the cylinder chambers.
Use proper tools and lubrication techniques to clean the chambers. Do it after or before every shooting session.
5. Grips Hurt While Shooting:
The grips of the Smith and Wesson 340PD are widely known to give many people a bad shooting experience. Some people experience blisters on their shooting hands.
The build quality of the grips on this revolver is not comfortable for some users, especially rookies.
You should get a new grip for the Smith and Wesson 340PD if you do not want to hurt your hands.
Houge or Pachmayr grips are best for this gun. A comfortable rubber grip like the Hogue Monogrip Rubber Grip for J Frame is a great option for this gun.
6. Unaligned Rear Sight:
The top strap of the Smith and Wesson 340PD’s rear sight may have a factory fault. Specifically, the strap on either side may be smaller than the other one.
As a result, the groove of the rear sight is also off-center. If you look at the rear sight while shooting, you will be able the see the other side of the strap due to the issue.
Since the top strap of the rear sight leading to the front sight is not adjustable horizontally, you cannot fix this issue. Also, the accuracy will decrease if you shoot with a faulty sight.
To get this issue fixed, you have to send the gun back to Smith and Wesson. They will either send you a new gun or replace the top part of the gun with an aligned rear sight.
