All parts in a Luger triggerpull is pivoting, while parts in a 1911 is sliding.
There is much less friction in pivoting parts than there is in sliding.
I do actually not belive you have felt on any well adjusted SIG P210 or Luger triggerpull.
THe thing that makes the luger and SIG triggerpulls so great is that when the gun cycles the searengagement is 0,5-1mm (.02-.04"). But when you come to the second stage in the triggerpull the searengement is close to 0.05mm (0.002") and there will be no creep at all.
At a 1911 you must have minimum 0,4 mm (0,016")searengement to have a safe triggerpull, if you have less the hammer will be likely to fall or even fires full auto.
The big searengement on the 1911 restricts the possibliitys of a heavy firststage at the triggerpull while this feature is fully possible on the luger and the SIG.
Just so you know it Johnny it's only in the US that 1911 are extremely popular for targetshooting.
In many countris like Switserland, Germany, Sweden the SIG P210 is the most popular gun and there is prob�¡bly around 200 SIG pistols on each 1911.
1/2" accuracy is very good out of a handgun, and its far better than any shooter ever can use.
I think you should have a look at some good sigs or lugers before you continue this discussion.
