My son recently bought a George lawrence holster thinking it would fit one of his S&W revolvers and it didn't. The number on the holster is 79 and it also has 680 & 677. I told him that someone on the S&W Forum will know. Your help will be appreciated.
Tom,,, call Vintage Gun Leather @ 1-866-478-5847,,,,david or michael are true authorities in GL leather and can tell you everything about your holster. If it won't fit your stuff, they will probably buy it from you,,,,bob
680 is the size code for a Colt 6" New Frontier .22 SA and a 6" Peacemaker .22 SA revolver.
677 is not listed in any of my catalogs and a holster generally doesn't have 2 size codes listed. 79 is the holster model number.
