CP On/Off question

[OPBN]

I got in an older CP On/Off recently. I noticed that it is fairly hard to turn on and off. Is this normal? I I have some other on/offs that I have had this issue with, but never a CP.

Also, it does not vent. Again, all my other CP on/offs vent. Are the two issues related?

I can get a pic of the on/off if necessary.

The older style CP on/offs seem harder to turn on and off, but even they vent in my experience. I've heard that there have been quite a few CP on/off asa knockoffs out and about, so it may be that you got something that's not genuine. Did you buy it new or used?

[OPBN]

Used. It's an older rail mount with a knurled on/off knob.

Did you pick this up from me by chance? Is this the one that had a weird brass insert with holes instead of an hourglass insert?

Used. It's an older rail mount with a knurled on/off knob.
Nevermind, the one I sold recently was a direct mount.

No. Insides of this one look very different from any that I have seen before. However, this isnt the first on/off that I have had thats been this way. I have an old unimount one that I think was made by invert that is difficult to get on and off as well.
