Brother Mouzone shoots Cheese with a plastic BB but tells him the next round in his gun is an "extra hot" hollow point load. It is not possible to set up an automatic pistol to feed such widely different ammunition. The plastic BB would require an ultra soft mainspring to feed reliably, but if you tried to fire a high pressure load with a projectile so much heavier on that same mainspring, the weapon is all but guaranteed to malfunction and could even injure the shooter. If you wanted to shoot such completely different ammunition out of the same weapon, it would have to be a revolver or manual repeater.
The insurance records for Sergei Malatov's BMW list it as a 540i, while the car shown to be his in an earlier scene is clearly a 3-series, not a 5-series.
