The nose being smooth and rounded is important.

For a 1900 I would not hesitate to reduce the protrusion a bit, but with a dremel it will be easy to go too far. I'd use very fine or fine emery cloth on a flat surface and rub the point against it, rotating and tilting to maintain a smooth rounded nose.

My experience with firing the 7,65mm 1900 is that Fiocchi ammo- which is usually too weak for a coil spring luger- works fine in a 1900; BUT they have thin primers and are easily punctured.

You sure don't want to damage the expensive and hard to find original bolt or extractor.

PPU ammo is somewhat hotter and I have not had any pierced primers with that brand.

Enjoy your 1900.
