trying to learn, 4 questions
What are the different type of finishes for automatics? Nitron? and which are the most durable? I'm not interested in chrome.
Someone told me that magazines that eject by a button near the trigger are not as trouble free as magazines that pull dowm from the bottom? is this true?
I've seen reference on manufacturer web sites that state something to the effect, barrel will last for six thousand rounds or some state twenty=thousand rounds. do guns have a finite life-span? or can guns be sent back to the manufacturer to be rebuilt?
Also I've seen guns with threading for flash supressors and silencer attachment, are there any drawbacks to the threading or the supressors?
I'm doing research for my first gun purchase, sure I'll be back with more questions.
