I have a Browning HP, Mauser Broomhandle, Kimber, Seecamp, Star, etc. I took each gun and fine tuned it with magazines, springs, polishing, and specfic ammo. I even got the old Star 1911 to 99% reliability.
The Sig P232 has a breech face that has been machined away, and the gun will never eject properly. The cup that holds the empty casing in place until it hits the ejector is milled away.
