i hunt deer with a maverick 88 and have for the last 3 years, i have been hunting where my shots are 50yds or less in deep woods. i get a deer every year except last year when i got permission to hunt another area and thought i would try there. its woods but also a few open fields of 100-150yds max. i tried a shot using my regular shotgun beads and missed on the last day. i don't have the money for a rifle and need my shotgun also for turkeys so i thought about sights. how are the Williams "Universal' Slugger Firesight?, they seem well built and wonder if anyone has them and how well they will improve my shooting? my gun isn't drill and tapped so i can't use a scope and i don't care much for scopes anyways. so for those that use these or something like them are they worth the $30 they cost on making better shots? thanks
