For some of the uniques that are good and useful being a pistol lover these are some of my favorites.
Ruby's (not sure how to obtain just my Live friends know I like them and drop by to give me new ones as they come across). Little Evie (my personal favorite). Obtained in Scarlett DLC in Magnys tower. It is also also unigue as it is not dropped but part of an random spawn where Mr Bubbles and Lil Sis spawn. You have to kill Mr Bubbles while doing little to no damage to LiL Sis. If you succeed than talk to Lil Sis she will give it to you.
Gwens Head found in boxes in dust. Not sure of exact locations because my friend just always picks it up quickly than dupes it back to me later.
The Law pistol part of reward for sidequest in Sanctuary but also can be obtained by farming the Sheriff in Lynchwood.
