You can buy spare extractors, but the FP's and trigger group parts are restricted. The only aftermarket FP is junk and breaks within 500 rnds.
If you could re design and make a good Mini fP, you would sell them like crazy.
Here's why, first, they break a lot, second, if you have modified your rifle in any way, Ruger will replace the FP, but takes out and keeps all your mods replacing them with their new junk parts.
No one wants to send their Minis to Ruger to get a new FP, but they have no choice.
The new model improved Minis are selling very well, but still break FP's and everyone I know would buy 2 or 3 spares if they could get a new pin. People will pay a decent amount for a Mini FP as long as it does not break.
If you ever want to make a new FP, PM me, I can give you a lot of info on the Mini's.
