9x19mm Parabellum replica 1:1 Scale. I have tried to make it as accurate as possible and when i print it my self its only a few hundreds of a milimeter off. It is made in two parts so you easily can print the bullet and casing in two different colors. I recomend supergluing the two pices together after printing but the choice is yours.

Tested in PLA and PLA Silk
