I finally got my sig p229 in .40s&w and could only be happier if one thing is possible. The one I got, due to availability, is double action only. My ? is; can I convert her to double/single action with a decocker like they normally come? The space is there on the frame for the decocker and from what I've see. On other p229's I would think its an easy job. Any help is much appreciated.
