Oh and Cheese that is prolly a good estimate on the Luger.They are excellent pistols and were expensive to build because they required a lot of hand fitting.
When you shoot it you may want to tilt it just a little to the left or right whichever is the most comfortable for you, It ejects the empties straight up so sometimes one will come down and land in the open breach and jam it. Don't hurt anything but it's a bother and can ruin a case. No biggy there if you don't save cases but I save all of them I can.
