I still find it rather ridiculous, when some people say "ive shot hundreds of rounds through mine and it hasn't locked up yet". Great, have you been struck by lightening yet? No?,...care to wave this metal rod around during a lightening storm? Or, the old ones locked up sometimes too...so stop worrying about a lock. Well, the new ones are at least twice as likely to lock by mistake....so why would you want to up your odds of an accidental locking? Just remove the lock si it'll never be an issue. This outs you ahead.
