I've had a .45 Colt 4" Redhawk for a month or so. The Hogue grips are the worst I've ever gotten on on factory revolver. They were uncomfortable for me, ugly, and a royal pain to take off. I now have Pachmayr Presentations on the gun, and much prefer them.
Mine came from the factory with a 9# trigger pull on S/A. After a few hundred rounds and some polishing it's now at 5# and has no creep. D/A pull is now around 9#. The spring is still completely stock.
Accuracy is good, with my best results so far coming from 255 cast SWC bullets and W/W 231 powder.
