Has anyone noticed the change of the CTC web site that indicates the LG 617 can also fit the G 20sf/21sf? It also shows this in their new 2010 catalog. Is this a mistake, or something they just discovered? Most of the web sites that sell CTC lasers, that I went on today, still do not list this model of laser grip as fitting the 21sf or 20sf. Just wondered if anyone else noticed. I see that some time in the future they are coming out with a specific model just for the 21sf/20sf, which will be their smaller diode, front activated version.
