Agree...especially on Johnson Bar Mooneys! There is a single point of failure in the gear actuator assembly of the older electric gears which is subject to a recurring AD for inspection and lubrication. If that fails, the gear is going nowhere, either up or down, even with the emergency gear extension since that, too, goes through the same gear set. But those failures are pretty rare since people are aware of the issue and (at least for me) monitor it pretty closely.
If interested, there's a little write-up here:

I disagree. The handle latch mechanism on manual Mooneys is flimsy and notorious for giving a false "locked" part to the business of "down and locked" indications. As weight is placed on the gear on touchdown, POP goes the handle bar (painfully into you or your passengers arm) and FLOP goes the gear. This is exactly how many a J-bar (Im willing to suggest the preponderance of them) Mooneys have been gear-upped through the decades and it has nothing to do with pilot error. Requiring of the pilot to triple yank and push up on the bar to test the locking plate and handle spring and effectively ensure pre-load of the latch is just bad design, not pilot error. Look up the guy taxiing on grass on youtube and FLOP goes the gear. That's just silly crappy design. Both the wear of the locker plate (original was cheap aluminum) and wear of the spring on the handle of the bar are gratuitous points of failure.
Having to hold the handle in order to ensure the gear doesn't flop is what we folks call having a fixed gear
Don't get me wrong, those short body Mooneys are efficient as hell. But that particular failure mode is just too much for my tolerance for what speed advantage one gets out of it... It only takes one instance and there goes the economy of operation.
