They said the mechanical work was completely within the lifetime warranty, so my only cost will be for the new sights. They also said they would credit me for the overnight shipping to Berryville, so my out-of-pocket for the whole thing should be negligible.
Their first shipment of production Ultimate Speed Sights isn't coming in until January, so they offered to install a set of their prototypes instead. I said sure, so it will be interesting to see how they turn out.
All in all, Wilson Combat's customer service is second to none.
I'm so glad I won't have to carry the Government CQB any more. It's a great gun, but a (literal) pain when you're 5'4" and carry appendix IWB. And I'll say it again, an Ed Brown Bobtail is the greatest single improvement to 1911 concealability ever devised.
Stay tuned for a review of the Ultimate Speed Sights. I have an Advanced Pistol Level III class next weekend including low-light work, night fighting, and trauma care. Should be a good one.
