Big Dot on Defender?
Anyone see any reason why this Big Dot wouldn't work on my Defender 1300?
Here's a link about it from Brownells
I'm not sure what the bead size is on the Winchester. Been searching, no luck yet.
Not sure on the fit for your Defender.. but I called them directly a few weeks back to inquire about the fit for a Ruger SP101. Very helpful and answered right away.
Maybe try calling them direct?
