Point of impact with factory sights...?
I just test fired two 9mm FrankenLugers, and they both worked flawlessly and grouped well. However, they also shot about 3" high at 15 yards, which is something I have seen other Lugers do as well.
I'm planning to get taller front sights, but I'm still curious to know if this is typical for Lugers. One of the uppers is completely matching, so it should hit pretty much as it did from the factory. So what have you guys seen? Do Lugers shoot at point of aim, or do they shoot high in general? |
Hi Olle,
Early P08's were sighted in at 100 meters and had front sight blades 5.0mm tall, from mid 1913 onward this was reduced to 50 meters by fitting a 5.5mm blade. Most of the early guns were fitted with the taller blade at the same time as they were retro-fitted with hold-opens. Regards, Norm |
It is my understanding that the later Lugers were sighted in at 50 meters. If this is the case, I would expect them to shoot high at 15 yards.
P.S. Norm types faster than I do!! |
My experience at 25 meters with 115 grs is a 6 o'clock hold on the ISSF C50 target. With most 124 grs I have to hold a little lower, around the 3 ring.

Gotcha. I kinda suspected that they had a different opinion on the effective range of a pistol back then.
So has anybody tried other sights for closer range, or do you just live with it? IIRC, the base is the same as on the P.38s, so if that's the case there should be a good assortment of heights to choose from. |

Yes I did. GT corrected a "gunsmith's mess" to an barreled upper that I owned, and he dovetailed the front sight base and installed a(I believe) Mauser rifle front sight. GT, please correct me if I am wrong. The front sight was too tall, and the Luger shot low. I would lower the front sight with a file and then benchrest shoot it for 20 yards with 115gr ammo. I finally hit the "golden height" and it is wonderful now with POA=POI. |
I know he has been using the Mauser sights, but they have a different dovetail. I would prefer not to create the "gunsmith's mess" you're talking about, and find something that's a direct fit.
The golden rule is to always modify the least expensive part (which is something I have learned the hard way...), so I would rather file a bit on a sight than on a barrel. ;) |
Or you can simply hold 3 inches below. I would. :bigbye:

This work that GT did was to a J Dewey aftermarket barrel that had no front sight dovetail to work with. It was not an OEM barrel. |
