I have a Leup 3-9 on a Knight 45.Bought it at Wally Wal-Mart,$230.I'm not much of Wal-Mart fan,but this scope been sittin on shelf for a year,marked down twice.

I couldn't ask for better optics.I have 2 Simmons and Bushnell,both good scopes but optics can't compare to the Leup!! Leup is a very pricy scope.As 1950KID mentioned If you can get one used,go for it!
