When families begin administering an estate that includes firearms, they often receive conflicting advice about inventories, transfers, appraisals, and Missouri probate law. Understanding what is actually required, and what is commonly misunderstood, helps executors make informed decisions while reducing uncertainty during one of life's most challenging transitions.

When Firearms Become Part of Probate
After the loss of a family member, executors often find themselves responsible for much more than settling financial accounts.
Gun safes need to be opened, collections must be identified, family members begin asking questions.
Someone has already searched online, another person has heard advice from a friend; before long, everyone seems to have a different opinion about what Missouri law actually requires.
Most of these misunderstandings are completely understandable. Unlike probate itself, most people only encounter firearm-related estate issues once in their lifetime.
This article addresses some of the most common questions we hear from families, executors, attorneys, and fiduciaries.
Do I Have to Inventory Every Firearm?
One of the most common misunderstandings involves Missouri probate statutes.
Many people believe Missouri Revised Statute §473.340 is the law that requires executors to inventory firearms.

In reality, the probate inventory requirement comes primarily from RSMo §473.233, while RSMo §473.340 generally addresses situations involving property that may have been concealed, removed, or improperly withheld from an estate.
Although the distinction may appear technical, understanding the difference helps executors appreciate why proper inventory and documentation matter from the very beginning of estate administration.
The practical takeaway is simple:
Every firearm should be properly identified, documented, and accounted for before important estate decisions are made.
Can Family Members Simply Take the Firearms?
This question comes up frequently.
Sometimes family members remove firearms shortly after a loved one passes away, believing they are simply protecting the collection or taking possession of property they expect to inherit. Good intentions and legal authority are not always the same thing.
While every situation is different, firearms are often part of the estate until they are lawfully distributed.

Executors are responsible for ensuring estate assets are properly accounted for before distribution. Professional documentation helps avoid misunderstandings while providing clarity for everyone involved.
Can I Simply Use Today's Market Value?
Not always.
One of the biggest misconceptions is that the current market value automatically becomes the value used during estate administration.
In many situations, the relevant value is the fair market value as of the owner's date of death, not today's market. Because firearm values can change significantly over time, establishing a documented valuation using the correct valuation date helps create consistency for beneficiaries, executors, and professional advisors.

Is a Gun Store Offer the Same as a Certified Appraisal?
No.
Both serve valuable, but very different purposes.
A firearm dealer evaluates collections to determine what they are willing to pay based upon current market conditions, inventory needs, and business considerations.
A certified appraisal documents a supported opinion of value for a specific purpose, such as probate, trust administration, insurance, litigation, or equitable distribution. Neither approach is inherently better, they simply answer different questions.
Do Suppressors and Other NFA Firearms Follow the Same Rules?
No.
National Firearms Act (NFA) items including suppressors, short-barreled rifles, machine guns, and certain other regulated firearms require additional federal considerations beyond standard firearms.
Executors should avoid making assumptions about these items until they have been properly identified and appropriate guidance has been obtained.
Fortunately, many estates never contain NFA firearms, when they do, early identification becomes especially important.
Should I Clean Old Firearms Before Having Them Evaluated?
Not necessarily.
Many families assume cleaning older firearms automatically increases value.
Sometimes it does, sometimes it reduces collectible value.
Original finishes, honest wear, historical markings, and even accompanying accessories can all contribute to collector interest.
Before investing time restoring older firearms, it is often worthwhile to identify exactly what the collection contains.
Are Firearms the Only Items That May Have Significant Value?
Often, no.
Many firearm collections include associated items that families unintentionally overlook, including:
Military bayonets
Optics and scopes
Ammunition
Magazines
Holsters
Reloading equipment
Military collectibles
Original boxes and documentation
In our experience, these associated assets are among the most frequently overlooked items during estate administration. These associated assets frequently contribute meaningful value to an estate and deserve the same careful identification as the firearms themselves.
What Should an Executor Do First?
Although every estate is unique, a few practical steps help reduce uncertainty:
Secure the collection.
Document what is present.
Avoid distributing firearms prematurely.
Identify potentially regulated items.
Preserve accessories and documentation.
Consider whether a professional appraisal is appropriate.
Consult qualified legal or firearm professionals when questions arise.

Taking these steps early often prevents much larger problems later.
Our Philosophy
At MDRF, we believe firearm collections deserve the same level of professional attention as any other significant estate asset.
Our role is not simply to identify firearms, our responsibility is to help families, executors, attorneys, trustees, and fiduciaries understand the options available to them so they can make informed decisions with confidence.
Sometimes those decisions involve keeping a collection, sometimes they involve distributing firearms among heirs, sometimes they involve certified appraisals, direct acquisition, or auction liquidation.
Professional guidance is about providing clarity, not steering clients toward a predetermined outcome.
Final Thoughts
Most Missouri probate misunderstandings begin with good intentions.
Families want to do the right thing.
Executors want to fulfill their responsibilities.
Attorneys want to protect their clients.

The challenge is that firearms introduce questions most people have never faced before.
Professional documentation, proper identification, and informed guidance help transform uncertainty into confident decisions.
Every estate is unique, every collection tells a different story.
Professional identification, accurate documentation, and informed guidance allow families and fiduciaries to make decisions based on facts instead of assumptions.
That's the foundation of responsible estate administration.
