I was window shopping at a local gun store and happened across a S & W model 915. It was a local trade in and the owner (a past seller of several guns to me) told me he was asking $375.00. It was in really good shape with no scratches, nicks, etc. and came with 2 15rd mags. However I would want to get different sights for it as the previous owner had tried painting white dots on the rear sight and a red dot on the front. I will probably have to have a smith install new sights. It sure would make a good big brother to my 6906. Any of you all have any advice you would like to offer?
