How to Choose the Right Red Dot Sight for the Taurus PT945
Choosing the Best Red Dot for Taurus PT945 depends on your intended use:
- Home Defense / Duty Carry: Go for rugged, combat-proven optics like Trijicon RMR Type 2 or Holosun 507C X2.
- Range & Target Shooting: Choose optics with larger windows such as the Vortex Venom or Burris FastFire 3 for quicker follow-ups.
- Concealed Carry: Lightweight models like Sig Sauer RomeoZero are ideal for minimal bulk.
- Battery & Brightness: Look for at least 20,000-hour battery life and auto-brightness functions.
- Mount Compatibility: The PT945 often requires a custom plate or dovetail mount (1911/Novak cut), depending on your optic’s footprint.
💡 Pro Tip: If your PT945 slide isn’t milled, consider a dovetail rear-sight mount — easy installation, no permanent modification.
FAQs
1. Can the Taurus PT945 be milled for a red dot?
Yes. Many gunsmiths can mill the slide for RMR or RMSc footprints. It’s a common upgrade for this model.
2. Do I need suppressor-height sights?
If you want co-witness capability, yes — especially with Trijicon or Holosun optics.
3. What’s the easiest red dot to install on a PT945 without milling?
The Burris FastFire 3 or Vortex Venom can mount using a dovetail adapter plate.
4. Are polymer-bodied optics like RomeoZero durable enough?
Surprisingly yes. For moderate recoil and EDC use, they perform well. For hard-duty use, stick to aluminum housings.
5. What’s the ideal MOA size for .45 ACP handguns?
A 3–6 MOA dot offers a balance between close-range speed and medium-range precision.
6. Do I need to re-zero after cleaning or removing the optic?
If you remove the optic from its base, you’ll likely need to re-zero. Quick-detach mounts help retain alignment.
