I was tempted to put my Aimpoint on my 458 but I went and shot it at the range Wednesday morning and I was able to touch bullets with two different bullets at 100 yards so I guess the iron sights on it are fine enough for the 150-200 yards that it is good for if I do my part. The Aimpoint would be nice though- just detracting from the appearance.
dennisinaz, if you do try out the Aimpoint on your 458 please write a post about it. Thanks.... idahoguy101
