Any one else having issures with the Sig P290RS with misfires? We picked one up for my wife but after a little shooting, we had 12-14 misfires, or light strikes, on about 135 rounds varying between 3 different ammo brands (all brand name). Most misfires would fire on a restrike but some took multiple restrikes. Not the firing percentage I was looking for in a self defense weapon. I called Sig and their customer service was very good, immediately arranged for paid shipment back to the factory....which made me wonder if they were hearing a lot of this problem.
