Well, some folks do seem to get a bit wrapped up around the axle when certain words and phrases are used ...
Granted, words mean things, and they can be used to influence the thoughts of others. History shows that words can obviously have a powerful effect on people.
The whole 'high capacity' magazine thing, though?
I remember when we were first told we were going to stop carrying issued and personally-owned revolvers and have to carry 9mm pistols. This was back around '89/90, before the whole 'high capacity feeding device' legislation occurred here in CA.
The S&W 9mm pistols we were being issued were casually referred to as 'high capacity' 9mm pistols by the firearms training staff and the folks receiving them ... even though this was several years before the federal ban and the state high capacity feeding device legislation. The standard capacity of the magazines was considered to be high capacity.
Why did we consider the S&W 59 and Browning HP 35 pistols to be 'high capacity'? Well, probably because they held more rounds than the revolvers, Colt Government Models & Commanders, S&W 39/X39's and the occasional Walther P38 that a lot of cops owned and carried.
Remember the 20-rd factory magazines for the S&W 9mm pistols, made for both the 59 & 69 series? They were simply referred to as extended capacity magazines, or more simply as "20-rd magazines" ... because they held more rounds than the standard high capacity magazines.
Some of the folks who carried a Browning HP 35 as plainclothes or off-duty weapons often said they liked the Browning for its 'high capacity magazine' back then, too.
Again, years before anyone even thought about limiting the capacity of magazines.
In the world of 6-shot revolvers and 7-9rd 9mm pistol magazines, the Browning and S&W 59 Series pistols were 'high capacity'.
Oh yeah, I forgot about the 'high capacity' 10-rd extended magazines for the 1911's ...
I thought there were something like 6 states with their own legislation identifying and controlling high capacity magazines, feeding devices, etc. That being the case, their legislation sets the legal definition for those states.
Everything else becomes an exercise in semantics.
