I recently bought a V89-40 pistol which is MP5 clone from Vector in 40 s&w. Took it to the range, and it shoots without any problems. Put 200 rounds of various ammo, and no stoppages. However, I noticed that spent rounds eject inconsistently. Some come out with very little force, some very forcefully. Also angles at which spent rounds come out vary grately. May be I am too picky, but I have a couple of hand guns and an AK-47 (M92 Yugo Krink). These guns have very consistent ejection. Any thoughts?
