Quoted:
The courts ruled that having ammo attached to the firearm, like in a sidesaddle, for example, does not make the firearm loaded and thus does not violate the law. It has to be in a position to be chambered/fired. Only "concealable weapons " (handguns, SBRs, SBSs, etc.) have to be locked up.

The term "loaded" has a commonly understood meaning: "to put a load or charge in (a device or piece of equipment) a gun" or "to put a load on or in a carrier, device, or container; esp: to insert the charge or cartridge into the chamber of a firearm." (Webster's New Collegiate Dict. (1976) p. 674.) Under the commonly understood meaning of the term "loaded," a firearm is "loaded" when a shell or cartridge has been placed into a position from which it can be fired; the shotgun is not "loaded" if the shell or cartridge is stored elsewhere and not yet placed in a firing position. The shells here were placed in a separate storage compartment of the shotgun and were not yet "loaded" as the term is commonly understood.

There is nothing in Health and Safety Code section 11370.1 which indicates the Legislature did not intend to use the term "loaded" in its commonly understood meaning.

We note Penal Code section 12031 states it is defining the term "loaded" "for the purposes of this section" (Pen. Code, § 12031, subd. (g)); it does not state it is applicable to a Health and Safety Code offense nor does Health and Safety Code section 11370.1 refer to the Penal Code definition.

Second, even if we were to accept the Attorney General's assertion that the definition of "loaded" contained in Penal Code section 12031, subdivision (g) applies to Health and Safety Code section 11370.1, subdivision (a), we would still conclude the shotgun here was not loaded.

[2] A statute "must be given a reasonable and commonsense interpretation consistent with the apparent purpose and intention of the Legislature, practical rather than technical in nature, and which, when applied, will result in wise policy rather than mischief or absurdity. [Citations.]" (Beaty v. Imperial Irrigation Dist. (1986) 186 Cal.App.3d 897, 902 [231 Cal.Rptr. 128].) "The words must be construed in context in light of the nature and obvious purpose of the statute where they appear. [Citation.]" (Decker v. City of Imperial Beach (1989) 209 Cal.App.3d 349, 354 [257 Cal.Rptr. 356]; Lakin v. Watkins Associated Industries (1993) 6 Cal.4th 644, 659 [25 Cal.Rptr.2d 109, 863 P.2d 179].)

Given the examples are all consistent with an intent to use the common meaning of "loaded," it follows the Legislature's use of the phrase "attached in any manner" to the firearm was intended to encompass a situation where a shell or cartridge might be attached to a firearm or "loaded" for firing by some unconventional method. The phrase does not demonstrate a clear Legislative intent to deem a firearm loaded no matter how a shell is attached to a firearm; in particular, it does not indicate a clear intent to deem a gun "loaded" when the ammunition, as here, is in a storage compartment which is not equivalent to either a magazine or clip and from which the ammunition cannot be fired. Our conclusion that the Legislature intended "loaded" as used in Penal Code section 12031 to reflect the common definition is supported by the court in People v. Heffner (1977) 70 Cal.App.3d 643, 650 [139 Cal.Rptr. 45], which reached the same conclusion …
