Gun control is reversed, not gradually eroded (5)

I believe the answer is:

luger

'gun' is the definition.
(type of pistol)

I can't explain the rest of the clue.

(Other definitions for luger that I've seen before include "German semi-automatic pistol" , "Shooter" , "Gun" , "Type of (German) automatic pistol" , "She goes down rapidly" .)

I've seen this clue in The Times.
