The Bullet Trap in Plano Texas. Rents guns for you to try. Not much of a selection when it comes to buying.
Also check out the Jackson Armory. Really overpriced pieces but the place is like a museum but no gun range. Also check out in Allen Texas Cabelas gun library. There is also a gun show August 22-23 in Fort Worth.
That's a GOOD place to visit, especially if you're into historical firearms. You'll need to be buzzed in the door, and this is near SMU, in Snider Plaza. Dress and groom respectably.
Also, it isn't far from there to the Beretta Gallery, one of five in the world! That's in historic Highland Park Shopping Center, at Preston Rd. and Mockingbird Ln. If you look respectable enough and are polite, you may be able to get them to bring out some SO series guns from the back. Even the guns out front are often quite ornate, with beautiful wood and engraving. Or, you can just buy a spare magazine for your M-92FS 9mm, or special grips. I don't think much of the knife designs I've seen there, but the guns, clothing, decorative statuettes etc. are terrific.
They were very patient with me one day as I waffled between two Urika Gold M-391 20 ga. shotguns. And the on-site gunsmith, trained in Brescia, had me mount the gun chosen and examined me to be sure that the stock didn't need adjustment. I couldn't have asked for better help and courtesy had I been in Holland & Holland or at Purdey's.
This shopping center is in suburban Highland Park and is, I think, the original shopping center in the USA, updated over the years, but retaining its basic SW Spanish décor. The city was laid out by the same architect who designed Beverly Hills, and the homes reflect that. Drive around a little and be impressed. Be glad that it's not you who has to cut the huge lawns!
I suggest dressing in basically Old Money or preppie style. If you wear an Izod shirt or dress shirt and khaki slacks and handsewn Timberland or similar moccasins, you'll fit in. You can also enter the theater there or the restaurants and other shops without raising any eyebrows. There's a Ralph Lauren shop in that center, too. And I think there's still a Tom Thumb grocer, with a quite nice wine selection. But I think the once excellent camera store there closed some years ago. Probably a victim of digital photography. But I think there's still a UPS or similar shipping store and some nice restaurants.
If you visit the Jackson Armory (not to be confused with the long-closed Jackson Arms store) that shopping center has a restaurant named Kuby's with good German style sausage lunches and the adjoining store carries such niceties as Lindt & Sprungli's orange-filled chocolate bars. I think they also sell their meats to go, but call first, if that's an issue.
If you haven't been to a really high class gun shop, try those two.
The Bullet Trap in Plano has a nice range, but the staff are bad about answering the phone and I sensed an elitist attitude there on occasion. But they had more retail and used/consignment guns than a previous post inferred.
On W. NW Hwy., there's a big gun and pawn shop that has a lot of good new and some used guns. They can be snooty aND RUDE. I BOUGHT a BERETTA 9mm THERE, AND THE CLeRK aCTED LIKE HE WAS DOInG ME A FAVoR TO BRING OUT SEVERAL EXAMPLES TO CHOOSE FROM. Sorry: the danged Caps Lock came on. No time to correct. Someone will know the name of this store, which displays at the big Market Hall gun show, too. It's slipped my mind at the moment. I buy very few guns these days, and haven't been by there in several years.
