That is the XD mod 2.0 chambered in 9mm. It is actually FDE, very close to Magpul's FDE.Which XD is that (the OD green one)? I shot one of those once and was surprised how much I liked it and how accurate it was for a sub-compact.
Less old school, more now school, Ruger SP 101 in .327 mag.
Ah heck, go big or go home, this one is for hunting T Rexs! A .700 H & H by Butch Searcy. Little prospective on the empty case there. The hunter (top knife) near it is 9" oal.
