I have a Crimson Trace on one of my SP-101's, and I like it a whole lot. As my eyes age more, I think the concept of laser sighting is growing on me.
And AZ, bearing in mind that I own several AMT DAO Backups, and they have all been super reliable for me, I would not buy one today. When they first came out in the early 80's, they were the bees knees: compact, dehorned, stainless and DAO in major calibers. They were amongst the first such pistols available. Now, there are many, many pistols available with a similar feature set that are much lighter in weight via the use of polymer or alloy frames. The weight of my Backups is what often prevents me from carrying them. I would point out though, that my 9 mm DAO Backup is still the smallest 9 mm pistol I own. I think you have to get down to the Rohrbaugh to find something smaller.
