I saw this Glock 21 for sale on a local forum. Based on the picture provided it obviuosly has finger grooves but does not appear to have a light rail. I have email the gentleman about the details of this gun but have not received a response as of yet. Did they make this variation for awhile and is it somewhat collectible, or does something seem amiss here. I am interested in the gun, but wanted to get thoughts from you guys before proceeding forward. Any input would be greatly appreciated! BTW-he is asking $425 for the gun, seems like a good deal if all is well.
