IS .40 CALIBER A GOOD COMBAT CALIBER?
Tired of the “9mm is king” circle-jerk? The .40 S&W still delivers heavier bullets (180 gr standard), better performance through auto glass & barriers, and meets/exceeds FBI specs with basic JHPs — something most modern 9mm loads only do with premium projectiles. Recoil is tamed in platforms built for it (HK USP, PX4 Storm, SIG P229), capacity loss is only 1–3 rounds, and the durability myth is overblown. If your pistol is your last line in a real fight, .40 gives you a measurable edge. Read the full breakdown at Adaptive ComTac.
