WardenWolf:
He talked to them. Ruger has them, but are keeping the ones they have for repairs, and won't sell them to individuals.
Apple a Day:
I think you'll find that your practice of swapping out recoil springs at 2000 round is doing it much more frequently than necessary. Those springs ought to be good for 5000 cycles, at last, and maybe much more! (I had a 95DC and put a lot more than 2000 trounds thru it without issues.)
That said, I can understand you wanting to have a backup.
As I noted earlier, go to the Numrich site, [
gunpartscorp.com] and ask them to notify you when the part you want is back in stock. You do this by selecting the part on their online listing, and clicking the WISH LIST option. It will be back in stock, one of these days.
And try calling Ruger again and see if they can /will give you the Specs for the springs. Some gunsmiths can MAKE springs, and Wolff Springs may have one or two that are very close to the Ruger spec, and you can mix and match and make your own set.
