Taking them home is part of employing them for their legitimate purposes, which are not subject to government accountability in the first place. Having them locked up in a distant repository of deniable accessibility infringes on the right to keep and the right to bear both.
If you get summoned to court, you're legally obliged to show up. You can't bring your gun with you when you do that, so the government clearly has legal premises for mandatorily disarming you under certain circumstances even though it doesn't appear to say anything about that in the constitution. It also doesn't appear to say anything about restricting people with past criminal records, and yet as far as I know that's a universal practice throughout the US.
As long as you're not denied access to the repository where your guns would be kept, your right to keep and bear them isn't infringed, and I don't see any constitutional language prohibiting the government from being in a position to confiscate weapons if deemed necessary. The 2nd ammendment doesn't appear to say anything about resisting US government authority nor have that intention in mind. Keeping guns safely stored in your home (don't see anything about that in the constitution either), they wouldn't be safe from government authority anyhow; since your guns would be registered, they'd know what you have and prepare their forces accordingly.
