I also had the same problem. It can be fixed with a 4" bladed #1 phillips screw driver. Loosen the Phillips screw that is inside cap, then unscrew the bolt lever. Add a little red or blue loctite threadlocker to the threads on the bolt lever. Reinstall lever and then snug down phillips screw in side the cap.
Hope this helps.

Tim - Not sure what you are referring to. I do not see any phillips-head screw on my PSI cartridge pen? The cap does unscrew but the slide won't come out due to the threaded fitting for the cap/clip assy. I can easily get to the internal slide so will just place a tiny bit of Loctite on the threads of the lever itself and then replace it in the slide body. No other diassembly is required to do this.
Hi Don
There is a small screw in the top cap that has to be loosened first.
This screw actually locks the lever in place so the threadlocker is just another way to stop it from loosening..
The screw acts as a set screw ,much like a Allen screw. It can only be reached by a long bladed Phillips when it is already assembled.
Any other help or info just shoot me a PM

Tim - excellent input! I just looked at the top part of the assy and can now see the phillips-head screw. When I loosen the screw, the lever easily moves about. So, this does look like a fix albeit not a very good one IMHO since it appears to be prone to loosening. Use of something like Locktite may still be the best solution to the problem. The loose screw solution is only going to come back again and again.
So, my recommendation is that for pens that have already been sold and are in the field that we send our customers (if we know who they are, that is) a short note letting them know there may be some loosening of the lever and that it can easily be corrected by tightening the phillips-head inside the upper portion of the pen.
Some sample text for this might be as follows:
-----------
To tighten-up the lever so it does not swivel when using the pen, follow these instructions:
Unscrew the bullet point and remove the spring and pen cartridge (being careful not to lose the spring). Once the bullet-point, spring and cartridge are removed, move the lever slide so it sits in the position as if you were going to write with the pen. Then, take a small 4" #1 Phillips-head screw-driver and insert it in the hole the cartridge came out of. Then, with the lever perpendicular to the body of the pen, tighten the screw so the lever is no longer easily moved. This should result in the lever not moving when you activate the pen cartridge for writing mode. DO NOT over-tighten the screw as you may damage the internal workings of the slide.
-----------
For pens that have not left our shops, I would recommend that we use the Locktite method so we don't have to worry about the issue in the future.
Thanks to everyone who gave input on this issue. Together I think we may have resolved a problem that could nag all of us for a long time.
EDIT - FWIW, I have found another three of my new cartridge pen kits with loose levers. The phillips-head screw wasn't even tight straight out of the kit packaging. CHECK YOU KITS CAREFULLY!!!...
