CCM Auto Trigger Cam Sticking?
 
I bought a brand new 45 CCM frame, auto trigger cam and Lever, and drilled pump arm.

The auto trigger cam is a tight fit going into the CCM frame. It also does not rotate smoothly at all. It takes a large amount of effort to rotate. I tried air tool oil, tri-flow, and dow 33. It doesn't help at all.

Looking in the hole where the cam goes in, I don't see any obstructions.

Sounds like just a snug fitting cam to hole.

Take the cam out of frame, Get a small piece of 600 wet dry sand paper, roll it into a cylinder (Like rolling a cigarette) Place into frame cam hole and rotate it around a few times, Swab the hole clean & Insert cam and try the fit, repeat if necessary.

My problem was the cam was a tiny bit big. I put the cam into a cordless drill and spun it while I hit it with 1000 grit sandpaper. About 30 sec and it was smooth as butter.

AHHHH NOOOOOO!

First back out the undertravel screw. I guarantee you this is the problem. It is under the grip frame. Back that out. It will most likely drop right in. I put together a .45 frame as well today - and mine would not drop in until I backed this screw out.

Try that before you modify anything.

I'm no stranger to CCM products. Mine was too tight with no internals. Mine was a tolerance issue, but probably only a few millionths. 30 sec w/ 1000 grit sandpaper couldnt remove too much SS.

Still a dissapointment when a brand new product doesnt work right and needs modification by the consumer. I still love CCM though:)

The tolerances on CCM products are really tight. My frame, the screws would hardly fit in the slots. I had to change to torx head screws to fit my gun better, and this resulted in drilling out the hole about 1-2millimeters to be able to fit the same threaded screw in.

The quality and care put into the machining of these products are impeccable, I'm sure the tolerance issues are just the result of trying to make everything fit perfectly.

Thanks, I tried that and it did not help. I removed the trigger from the frame to make sure. The head of the cam goes in okay on through the first hole, but it gets really tight as it goes through the second hole on the other side. I tried inserting the cam from the opposite side, and it appears that the hole is smaller on that side.

HVAC,

I meant no disrespect - Just wanted to take care of the obvious before he broke out the dremel.

Is it a dust frame or a polished frame?
