can a 380 be used in replacement of a 9x18? my CZ is a 9x18...
Comments
The bullet [and hence the case] is fatter at .365" vs. .355 of the others.
Just like the .38 S&W is fatter than the .38 Special.
Do it only if there is no more ammo left in the world for your gun.

Thanks guys?.I ordered a 1000 rnds of 9x18 Makarov...
Good.
Was once at an indoor range shooting my 9x18. The guy next to me was shooting the same gun but with .380 ammo. Heard some comments. Caught up with him in the store portion of the shop/range. I showed him some casings of his .380 and pointed out the splits and dark powder burns. He told me he was taking his pistol to the sandbox and that his father was a cop who told him that .380 would work just fine. I reminded him of his cursing over a couple of misfires and showed him my unsplit casings (factory ammo). The gun store owner concurred with me that he should only be using 9x18 Mak ammo. After determining that the store didn't sell 9x18 and with the consent of the store, I sold the guy a box of 9x18 HPs at my cost since he was in the service. I had recently purchased 1,000 rounds and could spare it.
Update: Hope you ordered non-steel cased and non-steel bullet ammo. Ranges hate the damagesteel causes to their backstops.
The Mak case finishes @ .705" OAL, but is a straight-walled configuration - it has no body taper.
However, the 9mm Luger & 9mm MAK rim dimensions are almost identical.
Before the flood of common 9x18mm surplus ball ammo arrived in the early-mid-90s, we'd cut-down common 9mm Luger cases to reload them using cast 95-100gr RNs sized to .363"-.365". It was a simple conversion: just shorten the case & bell the mouth w/ a custom 9 Mak expander.
Starting load data was very close to that for the .380 ACP.
