Hello. On my g23 and g30 sf, when the slide is locked open and I slam a new mag in, sometimes the slide shuts into battery on its own. It does NOT do this with my g27. From what I've read on the interwebs, this seems to be somewhat common. ANyone else experience this? What are your thoughts on it? The g23 has <2k and the g30 <1k rounds, so I'm pretty sure its not from wear. I cant see how it would be unsafe. But its not really cool to train with a gun that does something funny "sometimes".
