DelavanKs, I think it is a fine idea. I have an engraved 38/44, and like it a lot. I am currently planning on having a detective special engraved, and am in the process -- this has been going on now for about ten months -- of trying to decide on an engraver. (I also work for a living, so I have not searched full time!)

Prices and times can vary widely. I'd say at the lower end, less than $1K and maybe a month or two. I am not sure if there is a limit on the higher end, but several thousand is surely common. Waits can be months to years.

I suggest you get some books on it and start learning more about it. There are also a couple of engravers forums on the internet which are useful.

Don't make a hasty decision! Study up and find out exactly what you want. A lot of the fun is in the research!
