When I got my Sig Sauer 1911 22lr it was my intent for it to be a project gun. Although I was pleased with the performance and accuracy of the pistol, I just had to tweak it. After adding the Slide Alignment Cone from ZRTacical ( http://www.zrtacticalsolutions.com/
) and a full length guide rod & spring from GSGPro ( http://gsgpro.com/
) and the Dawson precision fiber optic front sight ( https://www.dawsonprecision.com/ProductDetail.jsp?LISTID=80000E56-1292881077
) I was very pleased with the improvement in performance with these upgrades. These are not just eye candy, they do what they're supposed to do.
