Price Factor 3: Accessories
Since SIG M18’s are modular, a lot of sellers typically bundle the gun with multiple modifications to make the gun more valuable.
This is still dependent on the buyer, as some prefer to buy only the base gun. Worn or low quality accessories might also get a haircut on value.
Original Box and Papers
If you have it in great condition, consider offering it as it can help with resale value.
Value: Usually adds $5 to $15, depending on condition.
Optics
High-quality optics from a well-known brand or from SIG themselves can definitely hike up the value.
Value: Around 30% to 50% of the accessory’s original value.
Weapon Laser/Light
Lights or lasers from a well-known brand will surely help with the value though less preferable than optics.
Value: Around 30% to 50% of the accessory’s original value.
Spare Magazines
It’s never bad to have more mags, especially if you have more SIG 21+1 mags.
Value: Around $10 to $15 per used mag.
