I just shot my gen 4 17 for the first time last night . It went great but the reason for this post is that i loaded the magazines i didn't count but as i shot realized that the magazines had 18 rounds in them. Is this a new thing with the gen 4`s? And before you start bashing i know you should only put 17 in, because you can damage the spring.
I've seen some used Glock mags that the spring had loosened enough to allow an extra round in them. Not a big deal so long as you are not storing them that way, I'd think having that added pressure on the mag for very long might be detrimental, just a guess though.
