Hi long time reader first time poster. I to have been waiting well over a month for my Fast Fire mount for my Glock. In the mean time I ordered a Weigand mount and put the Fast fire on my 627 revolver. I shot 2 steel plate matches with it on very bright days with no trouble finding the dot. Close friend had his J point with him at one match so we got to compare them, Burris much brighter and overall sight picture much clearer. So now hes got one on backorder. Scott
