They're not total junk, but they're not of particularly high quality, either.

Prometheus, the good titan.
First, you didn't specify what's wrong with it, so how do you expect an answer? Second, you're probably just as well to junk it, as any repairs are likely to cost more than the cheap Titan pistols are worth.
The Maverick is a solid pistol at a good price.
No. co2 airsoft pistols in general are plauged with leakage issues, especially a cheap crosman. Besides that, airsoft pistols are not a good investment unless you already have a good primairy rifle.
Aurora Phoenix Nebula Titan
Titan was the name used for firearms made for the firm FIE (Firearms Import Export) of Florida. They were low cost firearms made, for the most part, in what was West Germany. There were several different Titan pistols in different calibers. FIE has been out of business for 20 years now. If you can post a description and ALL markings, we would have better chance of getting you some information.
Sorry- no known public SN database on these guns, and the firm went bankrupt and closed about 27 years ago.
Varies by the pistol. Normaly better than spring.
Pistols.
Dose the HTC Titan a good smart phone dose it have good quality screen batter life and is it durable and tough? The HTC Titan is a good quality smart phone very durable and the better life is very good around 120 hour about give and take. The screen is a good size for that size of phone.
Their revolvers are.. their automatics, I've found to be a bit hit-or-miss. The PT92 and PT99 pistols are good pistols... essentially licence-made Berettas with better firer ergonomics. The Millenium... personally, I'm a bit lukewarm about that one.
