I've bought a couple of guns there, and was treated right.
My second-to-last pistol was a Kimber 1911 that I needed for work. I knew what I wanted, and went to the Dallas Gun Show to cruise for good deals on the Kimber Stainless Classic. I found one on a table from another dealer, and asked if it had the firing pin interlock device. (I didn't want one.) I was told rather gruffly that they were all the same. (This was 4 years ago.) The man's price was roughly $15 better than Bachman Pawn's, but Bachman Pawn's guy said, "Heck, I've got several new Series I Stainless Classics, right here." I ended up going by Bachman Pawn the next day and chose a Kimber. They let me try the triggers on each to choose my favorite. When I mentioned that I had chosen them over the other dealer because Bachman took better care of their customers, the counterman threw in an extra 8-round Kimber magazine, which completely made up the difference in the price.
Their location on Northwest Highway isn't the nicest side of Dallas, but the selection is good, the prices very competitive, the counterhelp knowledgable, and the service courteous and professional. What more could I want?
