Komodo vs. Cobra is a 2005 horror film that appears to be a a pseudo-remake of 2004's Curse of the Komodo. Both of these low-budget films were the product of B-movie schlock-meister Jim Wynorski, who seems to delight in recycling entire scripts, locations and casts like his mentor, Roger Corman.
The following weapons were used in the film Komodo vs. Cobra:
What appear to be Beretta 92FS pistols are wielded by several characters in the film. Mike A. Stoddard (Michael Paré) owns this gun. Dr. Richardson (Jay Richardson) fires this pistol at the one moment. Dr. Susan Richardson (Michelle Borth) briefly holds it, but, later gave it to Jerry Ryan (Ryan McTavish). These all appear to be airsoft replicas and the muzzle flashes added in post-production.
AR-15-Style Rifles
Some military men, one played by the "Gang Leader" in the first film, wield some type of AR-15 platform, likely an M4gery of some sort. Some have scopes, some have carrying handles. Probably also from the last film.
M1911A1
Michael Pare's gun switches from a Beretta to a M1911A1 at one point.
