I have had nothing but great service from Ruger. One of the reasons that almost all my wheelguns are Rugers.
My fist Ruger was a 7.5" SS, Super Blackhawk I purchased used in 1986 as I was leaving the state to attend college. Not long after I was shooting it and the Ejector Housing stud came off. I spoke to Ruger, told them I was the second owner and they said send it back. They repaired it free of charge and after about 500 rounds a week while in school, it has never come off.
Then, I picked up a .32 H&R Mag SSM as soon as they hit the shelves. Several years later I was letting a girlfriend shoot it when I heard a report that was way too quite. Before I could stop her, she fired off another round. Yup, bulged the barrel. Ruger replaced the barrel with no hassle. At the Time Federal was the only manufacturer of .32 H&R ammo. Their factory loads caused the problem. they gave me a $10 coupon good toward the purchase of more ammo. Ruger, who had no fault in the matter, replaced the barrel free.
I hadn't bought a NEW gun in many years, usually prefer to buy used. However, when I heard Ruger was offering a 7 shot .327 on the single Six frame, I had to have one. been wanting another .32 for years. Plus, it was stainless. I went to the store to buy a 4 5/8" model but noticed the one my dealer had in stock was missing the two upper grip frame screws. So, they sent it back and I bought the 5.5" version instead. I was too busy to fire it until a few weeks ago. In preparation to fire it I gave it a good cleaning and noticed that the two bottom grip frame screws were buggered. I had extra's on hand so went to replace them and found out that one of the screw holes in the frame was stripped. I called Ruger, they had me ship the revolver back to them (at their expense) and called me two days after receiving it to let me know that they were replacing it. I honestly expected them to tell me it wasn't covered. I suppose the fact that it was still unfired helped. So, while it seems that there may have been a little QC lacking in the screw installation department, the fact that Ruger made good with no questions asked makes me want to go out and buy one of the stainless .32 H&R's they just came out with.
No company gets it right 100% of the time. Mistakes are bound to happen. It is how the company handles those mistakes that sets them apart from the competition. So, far, in my experience, I cannot fault them.
