Zeus pistols are somewhat quiet. For a pistol they shoot hard. Depends on how the sound bounces off stuff etc.
Zeus G1s are extremely good pistols. Reliable, I used mine for close combat.
If you want added distance with pin point accuracy for a pistol get the G2. The G2 has two barrel attachments. We are a authorized Armotech dealer.
You may want a extra magazine or quick cap.
The quick cap allows you to reload much quicker than the standard "plug."
Other options include a hopper adapter, bottom line kit, and folding stock. Let me know if you have further questions.
