cassidy Posted November 9, 2008 Share Posted November 9, 2008 I have sceen "Bo-Mar type ribs on the slide" advertised on some 1911's. Is this different than a Bo-Mar adjustable rear sight? Link to comment Share on other sites More sharing options...
Jim Watson Posted November 9, 2008 Share Posted November 9, 2008 Yes. The rib is a substantial solid bar screwed to the top of the slide and holding front and rear sights. It adds about 5 ounces to the weight of the gun and it is all going into the recoiling mass of the slide. Not recommended for full charges, this is a bullseye wadcutter gun configuration.

cas Posted November 11, 2008 Share Posted November 11, 2008 (edited) Yes.... you don't want to shoot too much full power hardball out of it... the screws may shear or strip and it will come back and smash you in the face. I was young, I think the scar is mostly gone. Edited November 11, 2008 by cas Link to comment Share on other sites More sharing options...
Ignatz Posted November 15, 2008 Share Posted November 15, 2008 I never heard of a Bo-Mar rib shearing off during recoil, but now that its brought up............John Giles.. the famous Bullseye 45 builder use to cut a groove in his sight rib to match a groove he cut on top of the slide. A small steel bar made sure that his ribs never moved front or back. Link to comment Share on other sites More sharing options...
oak1971 Posted December 25, 2009 Share Posted December 25, 2009 I just found a 1969 Colt by John Giles. It has an extended rib that hangs off the muzzle an inch or so. I still have 600 or so left to pay on it till it comes home. They had 2 in the case, one in .38 and one in 45. I could only get one, so I picked the 45. It gives smooth a whole new meaning. The way the slide moves, the lock up and the trigger are out of this world. It is truly a precision instrument. Link to comment Share on other sites More sharing options...
