New to me Interarms Parabellum

Tango3,

After you have studied the luger a bit, you will realize that the striker with its attached firing pin is retracted when the pistol is charged, so no worries there.

The sear engagement lug and the sear bar are substantial steel items, and not likely to shear; add to that that the sear bar can't move when the safety is applied(a "sear blocking safety"), it is as safe as any cocked and locked firearm, IMO.

Actually there is much more metal engaged in a luger than the thin sear nose and hammer notch on a 1911.

As to leather, depending on what you want that can be a challenge, but a luger will fit many styles of 1911 holster!
Try it, one of my favorites is a 1911 lined flap holster, now holding a 4" bbl luger. Not exactly CC, but you get my drift; a Yaqui slide comes to mind as an option.

The original Mauser grip screws are over 40 years old now, and like any NOS parts, pricey.
You can find repro made screws at Sarco and Numrich for about $6 each, but do order them with something else or shipping is high for just two screws
