The submachine gun of my dreams? Well, only one will do it for me...
and that's known as Gun, Submachine, M1928A1...
also known as the Chicago Typewriter, properly known as the Thompson Submachine Gun.
Go ahead, pick one up. Feel the weight. 11 pounds of blued American steel, with that gorgeous compensator. Stock and forearm made from good walnut, mostly good figure, even for mass produced stocks. Add the Lyman adjustable sight, and a 30 round blued steel stick mag, and you're good to go.
Lock the bolt to the rear. Insert a 30 round stick, slap it upward to seat it. Now, bring the weapon to your shoulder and sight in. Pull the trigger firmly to the rear--yeah, baby! Feel the weapon vibrate as 230 grain ball ammunition goes to point of aim, 25 yards away, at 750 to 800 rounds per minute.
No muzzle climb. No excessive recoil. Just lots of caliber .45 Automatic Colt Pistol holes in the target. OH, YEAH!!!!
My dream rifle? I'll take a Nesika Bay or Stolle Swindlehurst action, with a Kreiger 30 inch medium contour barrel, chambered in 6.5-06 Improved. Bed it and float it in a McMillan A4 stock, with a Jewell trigger. Mount a NightForce 12-42x56 scope on it with the NP2 reticle--or maybe even a Leupold 45x fixed.
Excuse me, I have to go drool now.
