Do you put an edge guard on your knife prior to placing it in a sheath? Would you use a triger block on a revolver? I am guessing no to both. Use a quality pocket holster and follow these simple rules, you will have nothing to worry about. Your piece of mind should come from having the gun with you, not from making it harder to use the gun.
1.All guns are always loaded. Even if they are not, treat them as if they are.
2.Never let the muzzle cover anything you are not willing to destroy. (For those who insist that this particular gun is unloaded, see Rule 1.)
3.Keep your finger off the trigger till your sights are on the target. This is the Golden Rule. Its violation is directly responsible for about 60 percent of inadvertent discharges.
4.Identify your target, and what is behind it. Never shoot at anything that you have not positively identified.
