The original TimberWolf 17 frame had a few isolated complaints regarding inadvertent mag release. This issue was resolved by moving the mag spring retention hole off center creating more tension on the MR. The new release TimberWolf 19 frame has this feature incorporated into it already.
I highly recommend you try the MR as issued, I am sure you will be pleased. If anybody was still apprehensive regarding this issue we have a modified MR available via special request.
