P2000sk slings brass?

My "new" p2000sk (40 smith, looks pretty well used, not as advertised by any means) slings brass about twice as far as the newer P30L, so I'm just wondering.... No failure to feed, fire, or eject and this is with the Winchester 180 grain HP ranger load. Is this "normal" and what I can expect? Is the replacement spring on HK Parts the same spring for the 9mm, 40 & 357 Sig? Love the weapon, but it is slinging the brass quite a way at the range. Thanks in advance, tim

P.S. No, you can't have it to "help" me with my question...
