Reliable operation requires a steel mag catch. Shield Arms recommends replacing your OEM plastic mag catch with either their standard or premium steel mag catch offering. Using the OEM plastic catch or incompatible aftermarket catches may result in reliability issues. If you have a first-generation aluminum mag catch, an upgrade to a steel catch is necessary.
