Considerations & Trade-offs
- Designed for the Sig Sauer P365 Micro-Compact, so compatibility is specific to that platform rather than broader P365 variants or other pistols.
- The 12-round capacity is a practical middle ground, but it does not maximize round count compared with larger magazines.
- It fits flush, which keeps the profile compact, but that also means less magazine protrusion than extended options.
- A finger extension is included, which can change the feel of the grip compared with a flush baseplate alone.
