2D SESSION 
H. RES. 731 
Expressing the sense of the House of Representatives that mandates imposed 
on manufacturers requiring inclusion of unproven and unreliable tech-
nology in firearms is costly and punitive, and the prohibition of firearms 
without such features is an infringement on the rights of citizens under 
the Second Amendment. 
IN THE HOUSE OF REPRESENTATIVES 
MAY 16, 2016 
Mr. LAMALFA submitted the following resolution; which was referred to the 
Committee on the Judiciary 
RESOLUTION 
Expressing the sense of the House of Representatives that 
mandates imposed on manufacturers requiring inclusion 
of unproven and unreliable technology in firearms is cost-
ly and punitive, and the prohibition of firearms without 
such features is an infringement on the rights of citizens 
under the Second Amendment. 
Whereas California has implemented a law requiring firearms 
manufacturers to micro laser-engrave a gun’s make, 
model, and serial number on two or more internal parts 
of each semiautomatic pistol so that, in theory, the infor-
mation is imprinted on the cartridge casing in two loca-
tions when the firearm is fired;

Whereas other States and the District of Columbia are con-
sidering similar mandates; 
Whereas based on the current state of this nascent tech-
nology, it is impossible to microstamp a firearm in two 
locations and have the required identifying information 
imprinted on the cartridge casing when fired; 
Whereas the scientific literature concludes there is no existing 
microstamping technology that will reliably, consistently, 
and legibly imprint the required identifying information 
from the tip of the firing pin of a semiautomatic pistol 
onto the cartridge casing it fires; 
Whereas one study found that the impressions were not deci-
pherable nearly 50 percent of the time; 
Whereas the holder of the patent for the technology was a 
coauthor of peer-reviewed study that concluded, ‘‘legiti-
mate questions exist related to both the technical aspects, 
production costs, and database management associated 
with microstamping that should be addressed before wide 
scale implementation is legislatively mandated’’; 
Whereas a subsequent study noted the use of expensive scan-
ning electron microscope (SEM) technology still failed to 
solve the problems associated with microstamping; 
Whereas the microstamping process is costly and time-con-
suming, and threatens the employment of thousands in 
the firearms industry; 
Whereas the passage of legislation requiring its use would 
raise the cost of legal firearms by well over $200 per gun 
for both law-abiding citizens seeking to exercise their 
Second Amendment right and for United States law en-
forcement personnel; and

•HRES 731 IH 
Whereas manufacturers have publicly stated it is impossible 
for any manufacturer to comply with the provisions of 
the California law which are invalid, that cannot be en-
forced, and that will not contribute to improving public 
safety: Now, therefore, be it 
Resolved, That it is the sense of the House of Rep-
resentatives that— 
(1) mandates imposed on manufacturers requir-
ing inclusion of unproven and unreliable micro-
stamping technology in firearms is costly and puni-
tive; and 
(2) the prohibition of firearms without such fea-
tures is an infringement on the rights of citizens 
under the Second Amendment.
