I did find an aftermarket stock several years ago, but it was "expensive" and still not what I would want. I have been told (don't remember where) that the synthetic stock on the Striker is soft when it comes to attempting to bed it better, so the Super striker stock is better. For me I would have to cut out the thumbhole portion (like I have done with the with an old fajen thumbhole stock for a XP) to make it an ambi stock. I am unsure if that could be accomplished with the SS stock but it would be the way I would go if I purchased another Striker. The only other thing I am waiting on in terms of the Striker is a better trigger pull. I have had a Basix trigger on a Striker and was still not satisfied (Okay, so I am picky--I admit it!).
Accuracy potential in the Striker is great. If i did a Striker project it would meet those credentials (Oh, and yes it would be a switch barrel).
