Please read the similar topic on this page - Barrel Holes reversible?

I recently filled 3 x 5mm diameter hybrid holes in 2 Trubor bull barrels. The holes were then tapped for 6mm bolts. Then I placed two bullets down each barrel to cover the base of the holes. With JBL steel reinforced epoxy filling the holes and the threads of the bolts, I tightened each bolt until they touched the bullets, then backed off one quarter of a turn. After 24 hours of hardening I milled off the protruding bolts and took out the bullets. The end result was a much better shooting experience as I found that the removal of the hybrids made for a better and less 'wiggly' initial part of the recoil cycle. My long distance accuracy shots improved and the recoil difference was minimal. The gas volume increase also cleaned the compensator ports more. So far there has been no movement of the bolts. In hindsight I would also consider using a longer bolt with a non threaded portion near the head. One could then cut the bolt so that it binds at the top of the hybrid hole. Jim

Does anyone have first hand knowledge of the shooting differences between a full diameter bull barrel and hybrid compensator vs a thin sized barrel and a cone compensator? Obviously the second option should be lighter. I will be using a 5" barrel in a cut down slide in 9x23. The reason for asking is to determine whether it will be worthwhile to turn down a bull barrel and use a cone compensator. Thanks.

Go to Schuemann's web site and read up barrel timing. All of the tests are there relating to barrel lug problems.

I tried the aggressive grips -too sharp and I cannot move my hand position. Then I bead blasted them smoother - too slippery as the surface area between the spikes is too large. Then I added epoxy and 60 grit silicon Carbide grit - just perfect. I can now alter a bad grip position and also not slip once I apply any form of pressure.

I had the aggressive option on an SVI steel grip and didn't like it. Bead blasted it down in stages and still didn't like it. It went from too sharp to too slippery very quickly. The problem seems to be the large surface areas between the spikes. They are very very slippery. I am now going to fill the pockets with 60 grit silicon carbide. This is after much experimentation with grip tape stuck on top of the spikes. Overall I find that the best choice for me is where I am able to correct my grip after the draw - the original spikes prevent that.

Will Schumann has a long and very detailed barrel fitting article on his web site. He explains what problems can occur with various types of incorrect fittings.
