My holsters are not intended for use with modified guns or those fitted with trigger shoes. None of the products that I produce should be altered in any way. My  holsters are designed for use with a specific gun. Using a different gun or any alterations to our holsters could cause accidental discharge. With single-action pistols, cocked and locked carry is not recommended. It is not recommended to carry a gun during vigorous activity, such as jogging. ALL firearms are potentially dangerous. It is the user's responsibility to exercise extreme caution when handling or carrying any firearm. We (the manufacturer) are not responsible for any accidental or intentional injury resulting from the use of any gun or any of our products.
