Komodo vs. Cobra (2005)

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:

Handguns

Beretta 92FS

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.

"It's gonna take a lot more than a .38 to stop what's on this island"

Dr. Richardson (Jay Richardson) runs with a Beretta 92FS that seems locked back in the 'empty' position, but later fires it without loading. The location is the main building of the Los Angeles County Arboretum & Botanical Garden, which was also used in the director's previous film Curse of the Komodo.

This gun is pretty obviously a toy or replica of some sort.

M1911A1

Michael Pare's gun switches from a Beretta to a M1911A1 at one point.

Pre-War Colt M1911A1 Pistol - Commercial Model known as the "Colt Government Model" - .45 ACP. This has a deep Colt factory blued finish, common for commercial variants before and after the war.

It's clearly a 1911 now

Gun safety would be an issue here...if the gunfire were not CGI

Rifles

AR-15-Style Rifles

Some military men, one played by the "Gang Leader" in the first film, wield at least two separate variants of some type of AR-15 platform. These rifles are probably also from the last film. They are never seen clearly enough to identify, but some appear to be A2 rifles with fixed carrying handles and others appear to be "M4geries" with folding stocks, no carrying handle and an optic mounted on the rail.
