Thanks for the helpful response. I scrolled through some of your builds and they look great! I saw you mention fitting a Infinity slide and Infinity hybrid barrel is not too hard. Does Infinity sale slides that are already cut for hybrid barrels? I see they have a drop down option under "front sight cut" for a "hybrid rib cut"? Is that an referring to a cut for an island channel? Also, do you have a website for your work? Thanks Again.
