planning to use this sub-sonic ammunition in semi-automatic firearms:
Not all semi-automatic firearms are alike. Some gas ports are smaller than others, and in this instance (gas port) size matters.
While the vast majority of factory semi-automatic firearms will run this ammunition without issue, the lower muzzle velocity required to keep this ammunition sub-sonic may create cycling issues for some semi-automatic firearms with finely tuned gas ports.
If you experience this issue, it can likely be overcome by installing a lighter recoil spring, installing an adjustable gas block and/or increasing the diameter of the gas port.
Defiant Munitions recommends that all firearms repair and modification work be accomplished by a licensed and competent gunsmith.
