I'm looking to buy a Glock 19 gen 4 because of the simplicity, reliability, and durability many describe here, but am concerned about ejection issues. Online discussion of the problem seems to be all over the map - it only involved earlier production and it’s been fixed, or it only effected a few pistols and was wildly over-blown (and everything in between). I rented gen 4s last weekend at two different ranges and “brass to face” was a problem with both. Could be my form is flawed, I've been shooting for a few years, but I'm not an expert; could be the rentals weren't well maintained, too. But, could it also be that the G19 simply has design problems? Should I look at something else, take a $500 gamble, or simply buy with confidence? Sorry ahead of time if this is a topic that's been done to death already (feel free to direct me to other threads here). Thanks to any willing to offer advice.
