Went to my favorite pawn shop in town a few weeks back and a (new, not used) 4th gen 23 followed me home.  That's her on the left.  Love everything about it, and I've had no FTF's or FTE's with 200 rounds down the pipe, and also never been hit with brass.  After the first 100, I decided I'd like to improve the feel of the trigger.  Polished all metal on metal contact points in the fire control mechanism to a mirror or near mirror shine (by hand so as not to remove too much metal), and installed a Lone Wolf 3.5 pound connector and a ZEV competition trigger spring.  Trigger now feels awesome and I shot the second 100 rounds a lot better than the first.  

When inserting a mag in a pistol I always slam it home fairly hard and then tap the bottom to ensure it's seated properly, and I've never had this occur before but...if I use any more than what I would consider moderate force when inserting the mag, the slide closes and chambers a round.  I can make it happen every time if I try to, or if I focus I can prevent it every time, so I guess you could say it's really not an issue since I know how to avoid it.  That being said, if I load the gun the way I reflexively load a pistol, it becomes hot before I manually close the slide.  Some people I've told about this said "well hell, that just saves you a step and you're back on target quicker."  Interesting view but the bottom line is the pistol becomes hot without me intentionally making it hot, and this could potentially happen to someone not prepared for it causing an accidental discharge.  

A lady I shoot with somewhat frequently says the same thing happens with her M&P C.O.R.E.  Both are .40 cal.  

When attempting to recreate this "malfunction" with an empty mag, it does not happen.  Ever.  I can hit the base of the mag as hard as I can and the slide remains open.  This leads me to believe it's simply the shape and size of the .40 bullet I'm shooting, but I've been able to recreate with every ammo I've tried so far.  

Is this normal?  If not, suggestions?

It's called auto-forwarding.

Normal in Glocks?  Normal in .40 cal?  Normal ever?  I've heard of it happening but never known the fix, or if it's considered an issue...doesn't seem like it would be designed that way.

Try slamming the magazine straight up the magwell.  The heel of your palm is likely smacking the heel of the mag well imparting some forward momentum to the slide.


BTW, google Glock and auto-forwarding.

Been reading about it and it seems the general consensus is that it's normal and nothing to worry about.  Actually from what I've read sounds like most people like it.  Has me contemplating getting rid of my Glock now

Some do it and some don't.
Mine never has but a lot of the guys I work with do it.
