Then it's either the Sigma or P99 (A Walther Clone)
Probably the Sigma-the P99 has a fairly good rep-never handled one.
I stick with Glocks and decent 1911's now-just picked up a Para Ord SSP that is sweet
I'm voting for the Sigma (or Smegma as some wag refered to it). I've had a P99, and it was very reliable. Got rid of it because of the mag release. Found myself once trying to do a reload of a 1911 by pushing down on the trigger guard with my trigger finger P99 style. My first thought was "Under other circumstances this could be really embarassing!."
