KTP used to be better, but isn't bad as long as you stay away from weekends. Too many customers, and I have heard the most BS ever there from customers and sales people. But, it is certainly worth a stop. They have a NH FFL and can meet you over the line at a building they have for a transfer.
Riley's was a great place when Dick Riley owned it, then it went downhill with horrible staff after Dick sold it. I think they thought they were the ONLY stop for guns. Most of those bad staff have left, and a new generation of good guys is there now. There were a bunch of older gents there that didn't really care about you at all, just getting through the day, and would look at you and just walk away. I think that horrible gun store just down the street in Hooksett, forced them to get a little better.
Both Riley's and KTP are great for reloading.
Dick Riley has his turn as the NRA President in the 90's, nice fella. Not sure if he has passed.
Update, Dick passed in December of 2009. Was President of the NRA from 1990-1992. Dick, we in the state and other places miss ya. Thanks for all you did.
