I put a TruGlo Tru-Point-Turkey model TG946A sight on a 11-87 12ga a couple years ago. The package only has one model listed for Remington the TG946A model. Does anybody know if this would be the same model for the 11-87 20ga then? Also, I don't see this exact model listed in my 2014 gear catalogs, do they still make it? Thanks for any help.
