This 3D-printed bolt-release shroud is designed to be installed beneath the bolt-release latch of first-generation Beretta 1301 Tactical, Beretta 1301 Competition, and Beretta A400 shotguns. Its purpose is to help prevent unintended backward pivoting of the bolt-release latch, which can lead to the release of multiple shells from the magazine into the receiver, causing a jam.
To install or remove the shroud, you will need a T10 Torx driver to unscrew and screw the bolt-release latch screw.
Please note that this shroud is only compatible with and necessary for first-generation Beretta 1301 Tactical, 1301 Competition, and A400 models. The issue of shell dump malfunction has been addressed in second-generation Beretta 1301 and A400 shotguns through a redesign of the bolt-release latch.

DISCLAIMER!
If your life depends on the reliability of your shotgun, please refrain from using this shroud. It has not undergone extensive testing, and its effectiveness and reliability cannot be guaranteed. There is a risk that the shroud may cause jamming or impede the proper cycling of the shotgun, especially if dirt accumulates underneath it and interferes with the automatic movement of the bolt-release latch.
Additionally, the presence of dirt under or inside the shroud may obstruct the loading of shells into the magazine since the bolt-release latch needs to move backward during the loading process.
It is crucial to understand that this shroud does not provide absolute prevention against backward movement of the bolt-release latch and the resulting jam: Instead, it makes unintentional pivoting of the bolt-release latch more challenging.
Similar considerations apply to other shrouds available on the market, such as those sold by Beretta ($10) or Aridus Industries ($67).
If you decide to use this shroud despite the aforementioned risks, I cannot be held liable for any direct, indirect, incidental, special, exemplary, or consequential damages that may occur. This includes damages such as shotgun jamming, failure to load shells, inability to cycle, and similar issues.
In conclusion, exercise caution and remain aware of the potential risks involved if you choose to proceed with using this shroud.
UPDATE! To achieve a better 3D print quality, I recommend to use the remix created by db1337 for this object (https://www.thingiverse.com/thing:6010443): For reasons unbeknownst to me, his version consistently produces significantly superior results in 3D printing.
