71B Stuck CMT Modules

I've compared the dimensions between modules and the IDS with no significant differences and checked PCB insertion/removal forces. I can't figure out what the problem is, or more precisely, what I can do to fix it.

Any ideas?

I've noticed the exact same thing, thought it was just the luck of the draw with my samples; I'm glad it's not just me, if you know what I mean...

I typically turn the 71B upside-down and use a hardwood stick with angled tip to 'grab' the lip to pull the module out. No chance with just fingers, and any metal tool will damage the plastic handle (as prior owners have proven).

I've thought about either soap or some dry silicon lubricant on the sides; this will no doubt help a little, but I'm not sure of the long-term effects of having such material on the port walls, so I've held off.
