Sig P365 +3 Magazine Extension

TPM Sig P365 +3 Magazine Extension

This extension is made from machined 6061 Aluminum. This magazine extension will increase capacity, increase reload speed and mag drops, and overall functionality of your pistol. Available in various colors to customize to your pistol. Easy to install and rock solid once installed.

HKP highly recommends using a magazine loader when loading ammunition into our extended magazines due to increased spring tension versus factory.

Compatible With:

• Sig P365
• 17 round magazines only

Please note: This listing is for the magazine extension ONLY. This is not a complete magazine.  The referenced magazine capacity is the total capacity once the extension has been added to the factory magazine (which is not included).
