Glock 17
The Glock 17 is involved in the plot of the first episode, as the Mayans also stole Glock 17s from their warehouse (Note: Both the M4s and the Glocks were destined for the "Niners"). Several of the bikers, including Jax (Charlie Hunnam) also use them at the end of the episode when they steal the guns back from the Mayans.

The Jericho 941 is used by a Mayan duirng the raid on the new SOA charter in "Patch Over" (S1E04), in the next scene, the Mayans fire their weapons, but the muzzle flash is not seen, a remarkable CGI error.

Assault Rifles
AKM
The AKM features prominently in the series as the backbone of SAMCRO's gunrunning empire. Provided by their IRA contact the AKs are usually assembled by SAMCRO themselves.
AK47 Non-Gun
This series seems to take liberal use of non-guns or flash paper guns throughout (I am guessing for safety reasons). I watched one episode, I believe it was "Patch Over" where one of the Mayans shooting up the new SOA chapter literally seems to be making the "bang bang" motion with his arm instead of actually shooting anything.
M4A1 Carbine
The plot of the first episode revolves around a cache of M4A1 carbines stolen from the Sons by the Mayans (a rival biker gang). Clay (Ron Perlman) uses one at the end of the episode after taking it back from the Mayans.
