Loading Marushin M92 Beretta Cartridges

Your modelgun will only function correctly if your cartridges are prepared and loaded correctly. This is intended as a Step by Step guide on how to do this.
Cleaning of used cartridges is dealt with in a separate article...

Unlike Marushin’s MP40 and UZI 9mm cartridges, the M92 type uses rubber O-rings for better gas seal and a floating striker pin to suit the Beretta M92 series pistol’s hammer and firing pin operation.

As supplied, each box contains 15 cartridges and a bag containing 15 x 7mm dia. rubber O-rings

First of all, unscrew the cap from the cartridge and empty the case of it's contents.

These are

  • Cartridge Base
  • Striker Pin
  • Drilled and Grooved “Piston”
  • Main cartridge body

The Striker Pin will have already been fitted with 1, or 2 rubber O-rings depending on type.

The 5 cartridges supplied with the Beretta M9 “Dolphin” pistol I bought only had one O-ring whereas the additional cartridges I bought separately had 2.

I assume that Marushin redesigned the cartridge at some point.

The O-rings supplied loose in the bag need fitting into the groove in the outside edge of the drilled “piston” like so…

Tools required for loading are :-

1. Loading tool

2. Cotton Bud (Q-Tip)

3. Small Brush.

Mascara brushes are ideal for this! Get your Girlfriend, Wife, Mother or just go yourself to the nearest Make Up shop and borrow sample brushes (Debenhams are ideal )

Silicone or Lithium based grease make perfect lubricants

The all-impotant cap. These are Marushin 7mm caps but there are also MG and "Real Flame" to choose from.

Marushin cartridges rely on the cap acting as the blow back piston to operate your gun. The cap must be adequately greased to ensure smooth and free sliding inside the cartridge otherwise it will not function correctly. 

Step 5. Place the cap into the cartridge, powder charge facing up

Step 6. Using Widest end of the Loading Stick push the cap into the cartridge

Step 9. Smear a little grease onto the O-rings, then push the striker pin into the cartridge base.

Ensure the pin is in far enough so that it’s base, or the “primer” sits flush with the cartridge base.

N.B. Ignore the piston shown in this photo. This is a MGC cartridge, but primer position is exactly the same for Marushin M9 cartridges

Making sure the firing pin is grease free, screw the base into place,

and there you go,
