Aside from rail buffing/grinding, check the cut area of the frame where the recoil spring sits. Mine wasn't cut enough initially (I didn't round out the bottom enough), causing a tiny rough spot in the action. Mine didn't cause any failures, but I did notice polymer shavings on my recoil spring. After I cut out more of the frame, the action got a little smoother. I could see that causing issues with ftf.Dipped my toe in the P80 pool. Pretty sure there's still some grinding to be done--ftf on every round unless I manually rack it. Fun project though!
unotch just barely work as-is with the 940c. Mine have failure to return to battery every now and then. I'd never carry them EDC. They feel like a MM too short. If you measure a U next to a square or ETS, you'll notice the distance from the mag catch to the baseplate is like 3-4 mm shorter on the U.Something to note: When adding an Agency Syndicate polymer magwell to a pf940c, it will cause u-notch G19 mags to no longer catch. There is interference with the base plate and magwell. Square notch should not be a problem. Also, ETS 10rd mags work fine.
The magwell was orignally purchased for use on a pf940cl, but the grip is ever-so-slightly different and will not work. Only works on the 940c. Looks like the options for the CL are limited.
My locking block was snug and did require a couple light taps with a rubber mallet on first install, but after than it could be hand-pressed into the frame. I don't recall why I had to remove mine, but it does get easier. Easier to work with than the trigger housing in my opinion. That does suck about the spring. A tiny piece of metal, yet critical enough to prevent proper function when broken.Looks like I got a defective takedown lever spring in my 940c frame parts kit. The takedown lever literally fell out of the frame.
Eventually I'll get around to ordering a new one, but that's damned annoying. Extra annoying since now I will need to force the locking block out of the frame after I had to pound the f***er in in the first place.
- Oil the guide rod. Doesn't immediately seem to need it considering metal on polymer, but it sounds like a pair of rusty scissors out of the box and one might think it is the rail system at first.
