I don’t claim to be a Glock or Polymer80 guru by any means and I just learned a little detail that makes a world of difference. My problem was that with both my PF940v2 based Glock 34-style and PF940CL based Glock 17/19 hybrid, my bolts would lock open once in a while randomly. To be clear, I don’t mean they would stick open at some spot – the slide stop lever was engaging and locking the slides open.
|I do have a blog post about what to do if your slide is sticking open / getting caught part way during its operating cycle. Click here for that one.|
These random acts were far more frequent in the PF940CL and were driving me nuts. During a careful inspection, I noticed that the slide stop lever of the PF940CL had very, very little spring resistance pushing it down against the frame. More or less, the lever was flopping around!!
The first thing to check was whether I assembled it correctly or not. The spring on the slide stop lever should be under, or captured by, the top locking block pin. If it is not, then there isn’t enough tension to keep the lever down and it could then flop around and lock the slide open. In this case, it was fine.
So, it was assembled right but another thing struck me as odd. While it was stamped with the Glock part number for the G34’s lever, the finish had always struck me as off vs. other Glock parts. I bought the lever off eBay and suspect I was the victim of an inferior counterfeit part that had a weak spring.
Enter Vickers Tactical & The VTSS-001
I decided something must be up with the two Glock-34 extended slide lock levers that I bought off eBay – as in maybe they were counterfeits and not real OEM Glock parts. So you know, I really do like something that stick out a bit more than the stock Glock slide stop lever so I bought two Vickers Tactical units (Tango Down makes them) vs. reverting to OEM Glock 17 style levers.
Replacing The Lever
Always make sure your firearm is unloaded!!
So, I like to use a 5/32″ punch to push out the trigger housing pin while resting the pistol on a bench block. A bit of wiggling of the trigger can help it come out with relatively little force. You don’t need to beat it half to death. Some guys don’t use a hammer at all. I use one but with light taps.
Problem Solved For the PF940CL
Well, that was that – problem solved. While I was at it, I decided to upgrade my Glock 34-style PF940V2 pistol as well. I was quite impressed by the Vickers unit and the G34 would lock open once in a while too so I figured why not?
When I inspected the G34, I found out that I had somehow not captured the spring at some point so that was the problem but I really liked the Vickers unit so I bought one and replaced it as well. By the way, I really think this was a real G34 slide stop lever as the finish looked right.
So, I did the same as the above except I did push out the locking block pin first to make it easier to pull out the errant spring. I then did the same as the above.
I’m not a video kind of guy but I do realize sometimes a video can help a lot. I did some digging and Lenny Magill at Magill’s Glock Store has a great video that provides a lot of useful information about how to do the above and what to look out for.
I’m happy the problem of randomly locking open is solved. I definitely like the Vickers unit and am happy to recommend it.
Note, I have to buy all of my parts – nothing here was paid for by sponsors, etc. I do make a small amount if you click on an ad and buy something but that is it. You’re getting my real opinion on stuff.
