Whatever the logistics and supply situation, whatever the legal situation, whatever the tactical situation, "45" is THE most iconic American round. What the .303 is to the British, what 7.62x39mm is to every anti-Western revolutionary movement since the end of World War 2, what blaster gas is to the Star Wars universe (had to get some sci-fi in there somewhere), this size round, in two distinct forms, is in American firearms lore. Starting with the 1873 Single Action Army revolver in .45 (Long) Colt--which was brought back from retirement for use against Moro insurgents in the Philippines Insurrection--then moving to the .45ACP in the M1911 automatic till 1985, we see now a new role for the number as representative of him who is likely our last legitimate President, Donald J. Trump (the 45th POTUS). Whatever is to be our fate as a nation, should we not go down with a whimper, this round--in both calibers, as each has its advantages (LC: revolver-designed, .410 connection; ACP: automatic firepower)--ought to feature as fundament in the fight.
The reality we face is that, barring a major shift (and frankly, a Federalist 46 State-based action), American heritage is seemingly destined to relegation as a reactionary subculture. Lower-end defensive arms may eventually be all that is left of the traditional American RKBA. Semi-ironically, the culture and society of the future may be one where that close-in defense ability is exactly the most useful, personally and in terms of heritage.
But whatever the outcome, be it victory or defeat, let it be that history from an objective view bear remembrance of our Anglo-American/Western heritage in that number: 45.
