Just have to say, I don't give a rat's ass about "mag limits", and won't change anything I do based on such arbitrary and illegal nonsense.
It would behoove ALL of us to resist in this fashion. Fuck the enemy.
I think Sigs move is just the recognition of what is now a major trend in the biggest contracts out there. Everyone Sig does, or wants to, sell to, is going 9mm. I guess it's a streamlining of sorts.
.40 is slowly but surely going away. It won't fizzle like some others have though. I doubt any other major manufacturers will go this route, but then again, a few weeks ago I'd have said Sig wouldn't do this either.
My love affair with .40 was the next step after transitioning from 1911s in .45ACP. Carried and shot a G23 for years. Still have it.
But I've permanently converted to 9mm (G17 and G19, mostly the 19 these days) for the same reasons others have already stated.
My splits are best with it, and the capacity is great. Last week I carried the G19 with a 19 round mag in. Very comforting for riot control option.
