Pocket holsters allow you to carry in a jacket or pant pocket. Pocket carry is only practical with very small firearms or very large pockets. There are many pocket holster styles and materials. The most important thing is that it covers the trigger guard area completely. This protects and prevents accidental discharges. The pants you wear must also have enough room in the pockets to comfortably pocket the firearm. If you wear looser pant styles, or cargo pants with multiple pockets this may be a comfortable option for you. A pocket holster is also necessary when carrying your firearm in your purse or any other bag. It must cover the trigger guard to prevent you from accidentally pulling the trigger while reaching in your bag or getting small objects in your purse in the trigger guard area.
