Mossberg 930 SPX
Model: Mossberg 930 SPX
.
The Mossberg 930 (SPX) is one of the many models of autoloading 12 gauge shotguns that Mossberg offers. The SPX model is the "tactical" or "riot" model of their 930 series shotguns, chambered in 12 gauge with a 3" chamber.
The 930 can be had in a number of variants, from a duck gun to the above SPX variant with a short barrel and extended magazine tube. All models have the same operating system, a gas piston action, that is robust and reliable. The information in this page is specifically for the SPX "Special Purpose" variant, although the information herein can be applied to other models.
This page is in the middle of construction, and is pending additional content after further handling of the weapon. Please feel free to pitch in if you have experience with ANY 930 model, I only had a weekend to play with mine.
The Mossberg 930 SPX can be hard to find during certain parts of the year when production is focuses on fowling guns, but otherwise any FFL should be able to order one for you that matches the laws of your state.
The 930 SPX series has been adopted by a couple police forces, Blackwater (Now Academi), and served a very short period in US Army service. It has largely been overshadowed in use by Remington or Benneli shotguns in regards to military forces.
The 930's operation is extremely simple. Due to the simple design, it is easy to operate and maintain. There are limited known problems, all of which are inherent in a non-self-adusting gas-operated shotgun; The gun does not like low-recoil loads and will not completely cycle them. It will cycle target loads fine, but it will not cycle low-recoil "tactical" loads. It will not stovepipe with these rounds, they will simply not provide the pressure to completely cycle the bolt. Over the break-in course of 500 "target" walmart loads and 50 #00 (low-recoil tactical, personal experience on the above!), the only failures that occurred were due to the low-recoil ammunition. Every single one of them was remedied by working the action.
Condition One, or "Locked and Cocked." Chamber loaded, magazine full, hammer cocked and safety applied.
The 930, lacking an external hammer, cannot be in Condition Two.
Condition Three. Chamber empty, magazine full, hammer down, safety off.
How to unload the firearm and make safe. Presented in a numbered list.

Complexity
The 930's operation is extremely simple. Due to the simple design, it is easy to operate and maintain. There are limited known problems, all of which are inherent in a non-self-adusting gas-operated shotgun; The gun does not like low-recoil loads and will not completely cycle them. It will cycle target loads fine, but it will not cycle low-recoil "tactical" loads. It will not stovepipe with these rounds, they will simply not provide the pressure to completely cycle the bolt.

Controls
- Safety: Tang safety, located on the rear of the receiver. It is completely ambidextrous. Up for fire, down for safe.
- Bolt release: Located on the right side of the receiver, it is a large textured button. Push to release. This also operates the shell release. Push the loading gate in, then push the button to release a single round for safe unloading.
- Charging handle: Located on the right side, directly connected to the bolt. Large and textured for good grip in any circumstance.
- Bolt lock: Simple pull the bolt all the way to the rear with an empty magazine
Loading
Condition One, or "Locked and Cocked." Chamber loaded, magazine full, hammer cocked and safety applied.
- Lock bolt to the rear, safety on
- Place one round in the chamber and release the bolt
- Feed rounds into the magazine one round at a time until the magazine is full, making sure to insert the round fully to prevent a round from sticking behind the loading gate.
The 930, lacking an external hammer, cannot be in Condition Two.
Condition Three. Chamber empty, magazine full, hammer down, safety off.
- Safely insure chamber is empty by pulling bolt to the rear until it locks. Visually inspect both the follower and the chamber before releasing the bolt.
- Feed rounds into the magazine one round at a time until the magazine is full. Insert each round fully to prevent a round from releasing behind the loading gate.
- The firearm is now in Condition Three, ensure the barrel is always pointed in a safe direction. If immediate use is require, pull the bolt fully to the rear and release and the weapon will be ready to fire.
Unloading
How to unload the firearm and make safe. Presented in a numbered list.
- Ensure the safety is on.
- Pointing the firearm in a safe direction, turn it upside down so that you can see the loading gate and bolt release button.
- Push the loading gate fully into the receiver with one hand, wrapping it around the receiver to help support the firearm.
- Using the other hand, push in the bolt release. This should release one or two rounds, which can be physically removed from the loading gate. Repeat until the magazine is completely empty.
- Confirm the magazine is empty by holding the round release and touching the follower.
- Maintaining aim in a safe direction, turn the firearm over and pull the bolt handle all the way to the rear until it locks. This should clear the round out of the chamber. Visually and physically confirm the chamber is empty and there are no rounds on the elevator.
- Press the bolt release to close the bolt. The weapon is now unloaded and in a safe condition.
