Dumb question (regarding calibers), plenty more where this one came from...

The conversion requires changing the barrel and recoil spring. All else remains the same. (The front sight needs to be a slightly different height, but this generally comes with the barrel.)

An exception is the Old Model with flat recoil spring. Here, both calibers used the same spring and the Old Model in 9 mm should be restricted to low impulse loads. (124 grain bullet at 1050 fps)

There is some confusion about what's the right recoil spring. Many Lugers have an incorrect recoil spring in them already. I will eventually have comprehensive data on what's what in recoil springs. (My little research project.)
