The following guns were used in the series Justified:

Handguns

SIG-Sauer P226/"Non Gun"

The main sidearm used by Deputy US Marshal Raylan Givens (Timothy Olyphant) is a 9mm SIG-Sauer P226. In Season 1's "Fire in the Hole" (S1E1), he is seen pulling it on a fugitive suspect in Miami when he refuses to surrender and tries to shoot Raylan with a gun he had hidden underneath the table. The SIG he pulls at the beginning appears to be a SIG-Sauer "Non Gun" flashpaper replica. Later in the episode, Chief Deputy Art Mullen (Nick Searcy) uses a SIG P226 during the gunfight against Crowder's two "fat" Neo Nazi thugs.

Boyd Crowder (Walton Goggins) uses a Glock 17 to dispatch a suspected rat in his crew in Season 1's "Fire in the Hole" (S1E1). Later in the episode a couple of Glock 17s can be seen in the trunk of Chief Mullen's SUV, when he reaches to collect some weapons and ammo to confront Crowder's two "fat" Neo Nazi thugs.

Unknown Compact 1911A1

Raylan Givens carries an unknown compact 1911A1 after arriving in Kentucky in "Fire in the Hole" (S1E1). It's either a Commander or Officers size model most likely. The best view of it can be seen when he does a one handed brass check on it in the motel room before leaving to Ava's. It appears to have an added beveled mag well, 3 hole combat trigger and other custom features.

it appears the compact 1911 could possibly be the new Sig Sauer version: http://www.imfdb.org/index.php/Justified

It had the Gold Medallion, which almost always makes it a colt
