Thinking about RECOIL

[unspellable]

Approximate measurements from center line of bore to center of trigger in inches:

DWM Parabellum: 1-1/4

Star PD 1-1/2 (The original compact 45)
Glock 20 1-1/2 (10 mm)
Ruger P89 1-1/2 (9 mm)
Start Firestar 1-3/8 (Compact 40 S&W)
Llama IX-C 1-5/8 (1911 clone)

Looks like other pistols typically have the barrel about a quarter inch higher than the Luger.
