I know a lot of us own many manufacturers' offerings, so I have to share my recent experience with Ruger. I am impressed. I'd purchased a MKIII a while back, and one of the two mags that came with the gun just never worked right. So I emailed Ruger explaining the situation, and they replied within 24 hours offering a replacement mag. The mag arrived in 4 days! They even included a postage paid return envelope for the defective mag. Kudos to Ruger!
