I'm older than dirt. I started noticing my eyesight dimming when I hit 40. I tried night sights extensively and they didn't help me much. I've been intrigued with laser sights since the mid 80's, but never used them until several years ago. They help me immensely, especially in normal room light or lower light conditions. I had been complaining about the accuracy of my new (few months old) Sig P 320 Compact to a buddy of mine. A couple of days ago, I mounted a Crimson Trace CMR 201 to the rail. I took it to the indoor range. Once I sighted it in, I began to shoot at 25 yards (the maximum). I shot 15 shots, off-hand and unsupported. My group was 3-4". I reloaded a couple of more magazines and they were all in there. The laser convinced me that it ain't the gun, it's the older than dirt peepers. Good trigger control is still essential to get good hits, but the laser makes "sighting" much more accurate than iron sights for me. I have 5 Crimson Trace lasers on various guns.
