DALLAS — Gun rights activists are increasingly restless with leaders in Washington who promised all sorts of big wins for Second Amendment supporters if they would help deliver control of Capitol Hill and the White House to the Republican Party.

Now firmly in control, those leaders have failed to pass much of anything, including concealed-carry reciprocity — the National Rifle Association’s top legislative priority.

As the NRA convention kicks off in Dallas this week, activists are wondering where things went wrong.
