Guns fall off the approved list all the time. Whether the manufacturer just chooses to not market that model for a year, or drop production, or especialy for the smaller companies has to cut back during a bad period. Some guns are simply not produced anymore so there is no company paying money yearly to keep the product on a list, which means it has become illegal to sell in CA. Models previously sold and discontinued but still in widespread curculation have nobody paying to put or keep them on a list, and so importation into the state for sale becomes illegal. This is make and model approved list, not design approved list. 1911s without these features are only legal for sale if already on the list, and kept on the list.
For example when browsing the 10mm selection of handguns in CA I was surprised to find only 8 total handguns of that caliber are allowed in CA, and most are various glock models. Three Glock 20 models, two Glock 29 models, two Kimbers, and a single S&W revolver. All those great handguns no longer marketed have become illegal to import for sale in CA, nor those models once on the list and allowed to fall off. I was interested in a few models specificly that I learned were only legal outside CA. Needless to say the same can happen for many makes and models of firearms no longer produced or considered a source of major revenue by a company. Once that happens they cannot be put back on the list without complying with the new standards. Since this would require modifying the design of a firearm, many fine quality firearms will never make it on the list, especialy those not considered a priority.
Personal I think a magazine disconnect is more of a handicap than a safety mechinism. It means your potential self defense firearm can be rendered totaly useless if the mag disconnect is pressed while carrying and the mag is slightly unseated, or the perp grabs or ejects the magazine etc. It means the handgun is that much less capable in a grappling situation. It also adds one more design component that can wear out or fail causing the button or lever pressed while the mag is inside to not register a mag is inserted (like from wear on the part from friction slowly shrinking its dimensions) when one is and making the firearm design less reliable totaly unnecessarily by design. Safety is one thing, multiple unnecessary moving parts required to all be functioning flawlessly for the gun to fire and potentialy save your life is just stupid. These are not just passive mechanical devices, these are integrated into the gun design and must be functioning for the gun to do what it is designed to do. So maybe you flattened your backup magazine a little, perhaps tumbling around with a criminal, and you go to insert it in and ..oh it does not trip the little lever that needs to be internaly pressed for the gun to fire, and the gun has becomes worthless to you even though it is loaded and otherwise ready. Nevermined your essentialy disarmed during a reload even with one in the chamber.
Does anyone else think adding an extra passive mechanism intentionaly designed to make a weapon fail even when the trigger is intentionaly pulled is foolish?
