This is a long slide I have been working on when I have the time. Its been since Sep since I last worked on it. I am having an issue with the firing pen hole location and barrel location on between the two. The firing pen hole is a 9mm style. I have fit the barrel hood of the 6 inch Nowlin with little to no issue.

The barrel bushing as well. The barrel bushing is from EGW https://www.brownells.com/handgun-pa...?sku=296000085
. The issue is that I can not get the gauge for centering the firing pen hole to center in the chamber. As you can see with the pics below it is low by just a couple thousands or so. I have taken down the inside of the barrel bushings upper rear portion of the hood and lower front as I have a little barrel springing. This seems to have released some of the tension. How ever the barrel hood will not move any higher and the firming pen hole is still not lined up.
I have not ground down the barrel upper lugs due to Nowlin saying they do not need it. Lock up seems to be maxed out as it is. I seems that the only way to get the barrel to move up that extra thousands or so needed is to take down the upper lugs of the barrel. You can see from the picture that with the upper lugs blued they have very little play and what seems to be max contact, I assume as there is not a major mark to be found on them showing a high spot.
Its hard to see in the pics but one is of the breech face firing pen hole with the alignment gauge installed, the other with out it installed. You can see the slight mark it leaves just shy of the firing pen hole.
I really want to build this 100% correct. I feel right now that it would work and and run just fine, but my firing pen strikes are going to be off centered and we all know what that can lead to or cause.
In the past I have used Barstow barrels and never had this issue. How ever I had to a bit of fiddling with the upper lugs but also they where 5 inch barrels.
Suggestions?
