How Gunsumer data works

Manufacturer & editorial data — specifications, production years and history. Each value carries its own source and verification state.

Community-reported data — Owner Reports, ratings, round counts and reported issues. It is self-reported by owners and shown with a blue “Community-reported” label. It is not independently verified or laboratory-tested.

Official notices — recalls and service bulletins are listed only when published by a manufacturer or regulator, and are kept separate from owner-reported issues.

An Owner Report is one owner's structured, living account of a specific firearm — ratings, round count, how long they have owned it, how they use it and any issues — updated over time.

The Gunsumer Index is the aggregated community intelligence for a firearm, derived from Owner Reports and other structured community data: owner rating, would-buy-again percentage, community-reported rounds, ownership counts, category ratings, experience and ownership-duration distributions, long-term owner statistics and reported-issue aggregates. Each generation has its own Gunsumer Index, and a model can also be viewed across all generations.

Factual fields can cite one of these source levels:

• Manufacturer
• Official manual
• Official historical documentation
• Reputable secondary source
• Community contributor
• Unknown / unverified

A value is marked verified only after it has been checked against the cited source. Editorial entries that have not yet been checked are marked as unverified. When a value is not known it is displayed as unknown — Gunsumer never estimates specifications.

Every community metric shows how many responses it is based on. Headline values are withheld until at least 5 owners have answered, and samples are labelled as limited (5–19), moderate (20–99) or large (100+).

Percentages such as “would buy again” include a 95% confidence interval (Wilson score), so a result from 8 owners visibly carries more uncertainty than one from 800.

Long-term owners are those reporting 2+ years of ownership or 5,000+ rounds. Their satisfaction is shown next to all owners so you can see whether opinions change with time.

Round counts are reported by owners and summed per model. They are labelled “community-reported” because Gunsumer cannot verify them. Reports are validated for plausible ranges, keep an update history, and anomalous reports can be flagged and excluded from aggregates by moderators.

Issues are described by how many owners reported them — for example, “Reported by 7 of 120 Gunsumer owners (5.8%)” — never as confirmed defects. M counts each eligible owner once, even across a model’s generations, and N counts each owner once per category, however many issues they reported in it. Resolved issues keep counting; withdrawn ones never do. The cause is the owner’s view, never verified: only “the firearm itself” is ever counted as firearm-attributed, and an owner may name more than one cause.

• My Safe — your Own It, Owned It and Want It collection — is private by default.
• My Safe is a digital collection only. Gunsumer never records or infers where firearms are physically kept.
• Gunsumer never asks for serial numbers, home addresses, storage locations or precise location.
• Ownership counts below 5 are hidden so aggregate statistics cannot single anyone out.
• Analytics are anonymous: no user identifiers, IP addresses or device fingerprints are stored.
• Identifiable ownership information is never sold.

While Gunsumer is in development, some pages include synthetic Owner Reports generated to test the product. Fixture data comes from fixture accounts, uses identical random distributions for every firearm, and is always disclosed with a notice. It does not describe any real firearm or owner, and it is never loaded in production.
