Gun jamming is often caused by the dirt and debris that gets into the action of the gun. When this happens, it can cause the gun to misfire or not fire at all.
The grip is one of the most important factors in preventing a gun from jamming. A good grip will help you keep control of the gun and will help to keep the barrel clear of any dirt or debris. Make sure to hold the gun firmly with both hands and use a firm, even pressure when pulling the trigger.
If you are still having problems with your gun jamming, it is recommended that you take it to a gunsmith or firearms dealer for further examination. They will be able to properly diagnose the problem and recommend a course of action.
