While they are on the pricey side, SIG has sales that blow everyone else away.
When they introduced the P250, they were selling a kit with three slide lengths, three frame sizes, two mags for each one, all slides with night sights, for under $600. Employees at Sportsman's got 5% off of that too.
IIRC they also did a deal where if you bought a SIG 516, they threw in their AR .22 free or for like $50.
