This is a 9x 19MM Luger Cut Away, model. I suggest using supports for the case piece, and the Primer Anvil. The Plates in the 3MF are labeled for which need supports. You will see two versions of projectile. One Jacket and Core is for a 147 grain JHP, the other, is for a 115 grain RNCP. The bullets are made as copper-plated projectiles with a concave base. These are accurate for those style of projectiles.
Assembly is easy, reference pictures for assembly:
*Superglue. Don't cheap out. the stuff you get from groceries stores and retail stores is junk. Invest in some quality Hobby grade CA glue, Medium is my favorite. You'll be real upset if you get this all assembled and your entire model interior is hazed white from the glue off-gassing as it cures…..ask me how I know. LOL
