Lol. I guess $900 is too cheap for a stealth at this point in time. That went FAST! It no sooner made it up and it was GONE : )
Sounds like you have been turned on to some older misinformation. Sorry about that.
You have made it to the right place for solid info now though
If you would like it from the horses mouth here ya go:
Williams gun sights
(800) 530-9028
They have springs and a host of other things except for barrels and frames to do all said warranty work.
They have already serviced 2 of mine under warranty at no cost (THANKS AGAIN for the great job Williams/Remington)
Ask for Alex. He will tell you what they have. They are very knowledgeable and professional.
Here are a few more to look at:
