Last year I picked up a Sig Sauer target model .45 and over a period of time decided to swap the short recoil spring guide for a full length one made by Cylinder and Slide. I shot the pistol for awhile and noted that the full length guide added weight to the pistol. I didn't see any benefit and recently went back to the short guide as both taking the gun apart and putting it back together was more involved especially with the barrel bushing. Any thoughts on this?
