Claims made by the opponents of the technology include:
Stamped casing can only be traced to the last registered owner, not to the person who used the gun when the casings were stamped. In the case of a stolen gun, as is the case for most firearms used in crime, the stamped case would not lead to the criminal.
Unscrupulous individuals could collect discarded brass from a firing range and salt crime scenes with microstamped cases, thereby providing false evidence against innocent people and increasing the workload for investigators.[4]
High costs for testing the efficacy of the technique must be passed on to customers, increasing the cost of firearms for those who obtain them legally.[4]
Microstamping is easily defeated. Diamond coated files are inexpensive and will remove microstamping. Firing pins are normally replaceable and can be changed with simple tools or without tools. Firing a large number of rounds will wear down the microstamp.[4] Marked components such as slides, barrels, firing pins and ejectors are all easily and commonly replaced items.[5]
Microstamping is an immature, sole source technology, and has not been subjected to sufficient independent testing. Transfer of microstamped marks to the cases is less reliable than proponents claim.[4]
Microstamping would be irrelevant/non-applicable for implementation of revolvers as these types of weapons do not eject shell cases necessarily.
Ejected casings can be easily collected and removed from a crime scene.
