Affiliate Disclosure

Last updated: June 21, 2026

Some links are affiliate links. We may earn a commission. Compatibility data is independently sourced.

What that means

Some outbound links on CaliberAPI, including product and buy links, are affiliate links. If you click one and make a purchase, we may earn a commission at no additional cost to you. Those commissions help support the work of building and maintaining the dataset.

It does not affect our data

Affiliate relationships never influence our compatibility results. Which optics fit which pistols is determined by footprint specifications and independent sourcing, not by who pays us a commission. We do not change, hide, or reorder compatibility data based on affiliate arrangements.

Programs

We participate in, or are working toward, affiliate programs with firearms retailers and marketplaces. Specific programs will be listed here as they go live. Where a link earns us a commission, treat it as a sponsored affiliate link.

In plain compliance terms

We disclose these relationships in line with the U.S. Federal Trade Commission's guidelines on endorsements and affiliate marketing. Questions? Email [email protected].
