I had a similar experience a little over a year ago when I ordered a pair of full size synthetic grips for my model 60. Waited several weeks with no response, then called them and was informed that they were on back order and would be a couple more weeks. Couple more weeks passed and no grips, called again and was told still on backorder and no definite estimate of delivery. I got upset and told them to cancel the order.
Then a week later I swallowed my pride and re-ordered. That time I got a post card saying they were on back order and gave me an estimated date of delivery. This time I received them pretty close to the estimated date. I wasn't very happy with the whole process, but I was pleased with the grips when I finally got them.
