The retention device is both good and bad. On the good side, it makes it very easy to get everything lined up and crimped quickly. On the bad side, if something goes wrong it can cause you to destroy a perfectly good contact. We've found that contacts will occasionally get "stuck" in the crimper (we have the one from West Mountain Radio). When this happens, they get pulled upwards when you open the crimper, which resulted in the contact getting manged by the retention device - we have a contact that can't be used with a perfectly good crimp on it! So, we removed the retention device. It's not as easy to get things crimped without it, but now we don't mangle the contacts if they get stuck while crimping and can easily pry them out with a small screwdriver (usually the WAGO tool).
