WILLIAMS FIRESIGHTS on ruger website, ithink i got thru Midway. had front optic come loose after. 200 rounds , called them and they sent me all new fibers and instructions how to secure at no charge. NOTE: the camera makes the front site look small , it is actually larger diameter than the rear.
yes to replace you just cut the old ones , insert new fibre optics and cut a little long so there is a bit sticking out each end of the site then heat the ends w a bic lighter , they melt to a mushroom shape and youre all done
i took these pics today. i replaced the fibre optics last winter. they sent me 3 pieces of optics about 4 inches long each so i had plenty in case i screwed up by the way the sites do not snag on any of my holsters. for this gun i have : OWB Bear Creek, IWB N82 Tactical Pro, Side Guard appendix holster, and a Valor Gear ankle holster.
