(b) Is chambered to fire either centerfire ammunition or rimfire ammunition developing maximum permissible breech pressures above 19,000 copper units of pressure as standardized by the Sporting Arms and Ammunition Manufacturers Institute and (a) Uses an action mechanism which is substantially identical in design to any action mechanism manufactured in or before 1898 that was originally chambered for rimfire ammunition developing maximum safe permissible breech pressures below 19,000 copper units of pressure as standardized by the Sporting Arms and Ammunition Manufacturers Institute (3) A pistol, revolver, or firearm capable of being concealed upon the person, as those terms are defined in California Penal Code Section 16530, which: “Semi-automatic pistol” shall not include any assault weapons designated in California Penal Code Section 30510 (b) Is chambered for cartridges developing maximum permissible breech pressures above 24,100 copper units of pressure as standardized by the Sporting Arms and Ammunition Manufacturers Institute.įor purpose of this subsection, “semi-automatic pistol” shall mean a firearm, as defined in California Penal Code Section 17140, which is designed to be held and fired with one hand, and which does the following upon discharge: (i) fires the cartridge in the chamber, (ii) ejects the fired cartridge case, and (iii) loads a cartridge from the magazine into the chamber. (a) Is not originally equipped by the manufacturer with a locked-breech action and (1) A pistol, revolver, or firearm capable of being concealed upon the person, as those terms are defined in California Penal Code Section 16530, which contains a frame, barrel, breechblock, cylinder or slide that is not completely fabricated of heat-treated carbon steel, forged alloy or other material of equal or higher tensile strength (A) Except as provided in SCCC 7.90.040, the term “Saturday Night Special” shall mean any of the following: The words and phrases set forth below are defined as follows for purposes of this chapter: The purpose of this chapter is to ensure the health, safety and general welfare of Santa Cruz County citizens by eliminating the sale of cheaply made, inadequately designed and poorly manufactured handguns in Santa Cruz County. This chapter shall be known as the “Santa Cruz County Saturday Night Special/Junk Gun Sales Prohibition Ordinance.”. Someone else may come along who actually knows more about the machining, stessing, and stress-relieving of the different materials when the bore and rifling are done, as well as other machining properties of the different materials.PROHIBITION OF SATURDAY NIGHT SPECIALS/JUNK GUNSħ.90.050 Roster of Saturday Night Specials.ħ.90.060 Notification to manufacturers and dealers.ħ.90.150 Severability and validity. I don't make barrels, but this is how it was explained to me, so, take it for what it is worth. Machine guns have carbon steel barrels because of the high volume that they are subjected to, and they do not require the same level of precision, that a match barrel does. But I'm told that it is easer to get a more uniform bore and rifling in stainless steel barrels, and that that is the reason for using them on match rifles. Match shooters may run 10,000 rounds and change a barrel when they see groups start to open up a bit and no longer shrink after doing some some good copper removal treatment to the bore. Stainless steel can be a bit softer than high carbon steel barrels, and the bore may wear a bit faster in a high volume fired firearm. As others have said, it is not really a problem if care is taken to dry a barrel and oil it when cleaning it and storing it. The iron in a non-stailess steel barrel may be more prone to rust quickly. The carbon steel barrels have more carbon, and lack the nickel that is in stainless steel barrels, or at least the percentage.
