I am very happy with mine! I have only read of one person who wasn't...it was on the 1911 forum, and this one member was very unhappy with the way the frame was cast or machined around the grip safety. I think he went through two or three replacements with Ruger, and still isn't happy....and especially not with Ruger CS. That is definitely an exception in all the reports and posts I have read. I think Ruger definitely did it right on this pistol!
I bought a more expensive Colt, and I'm having an issue with the magazine catch. The Colt rep that participates on the forum was very quick to assist me, and send me a shipping label, etc. so I have no complaints about Colt's service. My point is, that even more expensive guns can have issues...but there seem to be so very few being reported with the SR1911s.
