Intended Use

These products are aftermarket grip accessories only; they do not alter firearm caliber, capacity, or factory safety mechanisms, and are designed solely to improve ergonomics and handling when used correctly.

Compatibility

These products are designed only for the specific firearm models listed on their individual product pages and installation resources. If a firearm model is not explicitly listed as compatible, it must be treated as non-compatible. Products must not be modified, forced, or installed on other models, as doing so can cause improper alignment, cracking, damage, or unsafe conditions.

Installation & Use

Always verify firearm model compatibility before installation. If uncertain, consult a qualified gunsmith. After installation, inspect for proper seating and alignment, and discontinue use immediately if looseness, cracks, or defects are observed.

Safety & Liability

Firearms must always be unloaded and handled safely during installation and inspection. Users are responsible for regular inspection of these products, and Rapid Engineering Inc. assumes no liability for injury, damage, or malfunction resulting from non-compatible use, improper installation, modification, or unsafe firearm handling.

Warranty & Returns

Warranty covers defects in materials or workmanship under normal use, but does not cover misuse, modification, or installation on incompatible models. For returns please follow the instructions found here- https://rapidengineeringinc.com/pages/warranty-and-return-policy
