Top Sig P365X Upgrades

Features to Love:

2. Trigger Upgrades
Options: Ramm Tactical Trigger Kit
The stock trigger on the P365X is decent, but there’s always room for improvement. The Sig OEM flat trigger reduces finger fatigue and provides a smoother, more consistent pull. Alternatively, the Ramm Tactical Trigger Kit can lighten and smooth the trigger pull. It is a great aftermarket upgrade to completely change the way your pistol shoots.
Why Upgrade?
- Faster reset for follow-up shots.
- Enhanced accuracy with a cleaner break.
- Ideal for both EDC and range use.

Key Benefits:
- Better grip, even with sweaty or gloved hands.
- Improved recoil management.
- Enhanced aesthetics with a tactical look.
