There might be a very high end airsoft pistol which a factory sight can be fitted to, but I'm a bit doubtful about it. With most of your airsoft pistols, the sights are part of the single piece moulding which the slide is made from - they're not like real factory sights, which are separate units that have to be tapped into place after manufacture.
Yes, a front and a rear sight.
Your eye is the rear sight.
where can I buy a new rear sight for a spesco 38 special
I believe the serial number is behind or to the rear of the rear sight. you should be able to see serial number without removing sight
What is a rear disc patch?
Tap it gently. that's all it takes! This is from the manual: Your rifle has been sighted-in and test-fired at the factory. Due to individual shooting characteristics, however, sighting should be range verified. 1.) Vertical Correction (Elevation) To raise the point of impact, raise the rear sight, by moving the sight elevator rearward. To lower the point of impact, lower the rear sight, by moving the sight elevator forward. The sight can be raised and lowered by moving the stepped elevator forward and back with your thumb. To move the point of impact to the left, tap the rear sight base to the left. To move the point of impact to the right, tap the rear sight base to the right. Windage adjustments to the rear sight can be made by gently tapping the dovetail portion of the rear sight in the desired direction.

DPMS/Panther Arms isn't the actual manufacturer of the airsoft replicas - they've only given license for Cyberguns to use their logo on the products. So going to the DPMS website will be of no use to you. Most airsoft supply companies will offer something in stock, or will be able to order the part for you. A simple web search of 'airsoft suppliers' should do the trick, or you may even search for suppliers in your specific state. If you cannot find the original carrying handle/rear sight, or the parts necessary to replace it, there's always the option of BUIS (Back Up Iron Sights), provided you have a detachable carrying handle. UTG (also marketed as Leapers) makes these specifically for airsoft guns.
