Krazy 8 uses a S&W 4506 in "Pilot" (S1E01). Not long after, Walt becomes its new owner before Jesse finally disposes of it in the following episode "Cat's in the Bag…" (S1E02).
DEA Agent Hank Schrader (Dean Norris) shows off his issue Glock 22 during the party in the first episode "Pilot" (S1E01). He actually refers to it as a Glock 22 and praises the power of the .40-caliber round over 9x19mm (claiming to have seen the latter cartridge ricochet off a car windshield).
The Ruger KGP-161 appears to be Emilio's gun and is taken out of the yellow bag by Walter and later dissolved in the tub in "Cat's in the Bag…" (S1E02).
In "Pilot" (S1E01), the DEA tactical team that raids Jesse Pinkman's meth lab is armed mostly with short-barreled M4-type rifles. The weapons appear to be Mk. 18 Mod 0s that have the front sight posts removed, full-length rail forearms, and Crane stocks and Vltor MOD stocks. Most have EOTech holographic sights and back-up iron sights, though at least one rifle has the standard carry handle/iron sight combination and no other sights.
