I made an Artillery Luger out of spare parts using Sarco's barrel and their Artillery rear sight and took it out to the range to try it and Boy!, was I surprised.
First let me tell you the Artillery barrel they sell is not bad, a little high priced, $225, but well made.
The rear sight is well made also, but way over priced at $175 and took a little minor fitting.
Now how did it shoot you ask, first shot at 25 yards was almost dead center, I had to do a double take and them fired another round,it hit in the same spot, this is without any adjustments to the front or rear sights, just dumb luck I guess.
You can see in the picture of the target how the rest of the shot went.
I was very pleased with how well the home made Artillery luger shot.
