Neither
All airsoft can jam. Phrase your question better. Such as Does blowback airsoft jam more than spring airsoft?
Both can be dangerous if used improperly
Not sure what the question is, be more specific, each gun has its own magazines, and spring guns suck if not bolt action rifles or shotguns.
No. even though some spring guns have great range, co2 allows you to fire more then once before reloading.
if its spring pistol get a new spring or a better piston (if they even make upgraded pistons for pistols) if its gas i cant help you
airsoft is more fun played both airsoft is more realistic
yes they are more dangerous than regular alligators especially in spring when their babies are born!
No. Aspects which determine how powerful an airsoft gun is actually it's spring (stronger/harder the spring means bigger fps), compression (better compression = better fps), and weight of the BBs we use (heavier BBs in the same fps can deliver bigger energy).Edit: If a gun that is automatic in real life is spring and very inexpensive, it is probably cheaply made and therefore almost definitely weak. However, "manual" guns that are spring are usually at least fairly powerful, such as bolt action sniper rifles.
It depends on a few things. As a general rule, the more you paid for it the longer it will last. Also if it is gas or spring or electric. It depends on how much you use it and also how you treat. I have a spring P228 which I take good care of (never leave it cocked, keep the magazine out, dont overfill the magazine, dont cock it too roughly) But the more you use a spring gun, the more the spring wears out. If it does the best thing to do is take it too a airsoft dealer or a skirmish site and ask about repairs. Hope I helped. :)
No, paintball is more commonly known and is more popular. The last person was correct but I'll give a more detailed answer. Paintball is more popular than Airsoft but more young kids play Airsoft because it's not as dangerous. Paintball players normally start at around 13 while Airsoft players normally start around 11. Airsoft is something that you can do in the back yard, while Paintball is something you normally need to go to a place that hosts Paintball games for.
Self protection? As in keeping robbers away from your house? I guess i would go with a gas rifle. They are often the most powerful, but are more expensive. If your are looking for home security, an airsoft gun would not be your best bet. I would go with an actual pellet gun or air rifle. Airsoft guns are more for recreation.
No, it shoots 3 at once.
