Just got a new spare Glock Slide Stop Lever SP02919. its marked 2912-4 and has a noticable change to the older 2912-3 marked slide stop levers of the same part number. The -4 version as a small step built in in front of the tab that actuates on the magazine follower.
Anyone know the reason for the design change? Another unannounced Gen4 redesign? any issues with this new version in gen 2 & 3 Gocks? It is not The different one for the Gen 1 2-pin G17 with the triangle hump or the G20/21SF version. (know someone would ask) |
This is what every slide stop I've purchased over the last 20 years looks like. Including as recently as a year ago.
The top one in this pic is what I got yesterday. -4 version http://glock.pro/attachments/glock-tech-warranty/5340d1378587392-most-common-glock-mods-slide-stop-levers-copy.jpg Same part number. |

Interesting. I'll have to pull a couple of mine apart this weekend (out of town) and take a look. I only have my gen 4 19 with me right now. Its a minor change. But after 20 years of owning Glocks as soon as i took it out of the package i was thinking what the hell is this? I'm wondering the why. It looks as if they added clearance in one spot but then built up another spot. To prevent over activating the slide stop maybe? |

I should clarify - I am going to look at a few of mine and see if there is a difference in Gen 3 vs 4 or if maybe it has something to do with the reason my newer guns launch empty mags out while the older ones just sort of fall out...except when they don't come out at all.

Can somebody help me see the difference you're describing? I recently acquired a brand new G17 Gen3 and it came with the stock one, but I went ahead and ordered the Glock Factory "Extended" slide lock as pictured on the bottom of that pic you linked...From what I can also tell, this "Extended" slide stop come standard on the G34/35 - but what I can't seem to identifiy is the difference between the top one in the picture and the stand-alone pic.
What am I missing? |

What am I missing? Downward slope ending in a dip almost like a check mark and the adjacent platue vs a relative straight flat surface. |

Ahh, maybe its the angle...now that you explain it I do see it...
What impact would this have on function? A different way in which the magazine follower engages the slide stop? Different (more aggressive) geometry? I shot a friend's Glock 30 this past weekend and when you slam a magazine home it releases the slide stop and also about every 3rd magazine the slide doesn't lock back on an empty chamber. I wonder if this could be related. |

I wonder if this could be related. That sounds like a worn out slide stop spring and/or incorrectly installed slide stop (which is very common). The two could be related, but not necessarily. When I do an empty reload, the slide goes forward chambering a round about 3/4 of the time. I attribute it to the forcefulness in which I seat the magazine. I know it's not my thumb hitting the slide stop after trying various grips with the same results. This has happened since I've been shooting Glocks; about 18 years. It's done it with the first Glock I bought all the way through the most recent (23, two 21s, 26, 19, 17, 34, 20, Gen4 19). It could be a worn slide stop and it could also be due to the shooter's grip and thumb placement (if right handed.) The slide not locking open on the last round is, in my experience, either related to the shooter's grip (right handed grip and inadvertently thumbing the slide stop) or a mag spring/follower issue. One recruit was having major issues with that and I found out his G17 mags all had G19 springs, so there wasn't enough upward pressure to force the slide stop up. It can also be a worn/rounded slide stop or, every blue moon, a very worn slide notch. The parts are cheap enough and easy enough to replace that there isn't a good reason not to replace suspect parts. One can do a lot to accurately diagnose these things too. |
