Gunslinger

Gunslinger is a Fallout 3, Fallout: New Vegas and Fallout 4 perk.

Effects
While using a pistol (or similar one-handed weapon), your chance to hit in V.A.T.S. is increased by 25%. As with all perks that increase your chance to hit in V.A.T.S., this bonus is multiplicative, not additive.

Effects
Ranks 2 and 3 each add 25% range, for +50% total. Rank 4 gives a 6% chance to disarm. Rank 5 increases this to an 8% chance to disarm, plus adds an 8% chance to cripple the limb you hit.

Affected weapons in Fallout 4
Asterisk (*) marked weapons may not have a shoulder supported stock installed to benefit from this perk. Having a stock will make these weapons benefit from Rifleman instead.
