Dave, the forend has nothing to do with ejector timing. Don't worry about ejector timing until you get the lever to get into proper position. Judging from the expenses you are about to incurr from Coles, I suggest you do it yourself. I have never sent a Beretta out for barrel fitting. Maybe you should take my advice to clean out the holes and then take pictures to show us how far the lever goes over. If those who look at the pictures pronounce the gun safe to fire, you should test fire the gun and let us know how things work. If the lever position can be marked, observe how far the locking lugs extend at that lever position. If it is a comfortable position, shoot the gun twenty five times to see if things work well and maybe the lever will come home a bit. Let us know. This is the way I fit my Beretta barrels if I don't have a Beretta gunsmith to help me.
