Help with a Commercial Luger

[reiver]

Ok, no laughing!
I've been working on the height of the front sight blade and measured 6/8ths of an in. from center bore to top of blade to match the height of the navy rear.
I cut down the junk front blade that came with to the appropriate height and used duct tape to secure it...lol, I know. However, it worked, the front sight did not move during shooting. Six rounds at 30 feet. I'll leave the blade a bit high when mounting as I can always reduce it but a good start point. I live in the country and can shoot on my property.
