That is great, got one!
But don't expect to be able to stop at one.
And you are correct about the foibles of the grips and sights.
For shooting, you can always get a pair of cheaper replacement grips and "save" the originals.
As to the sights, they are small for a reason, like many/most military pistols, they are not for target shooting; but, I think they are better than the original very small 1911 sights! But target sights they are not.
Enjoy.
