How can you know a thumb saftey is effectively blocking the sear other than testing by pulling the trigger? Is there a chance for malfunction?

Attempting to dry fire is the true proof of the pudding, but you can view the engagement of the safety lug to the sear by assembling the gun minus the grip safety. I'm not sure what your second question alludes to, but the answer is most likely yes! :scratch:

You want to cock the hammer. Put the safety on. Pull the trigger.

Now, here's the real test. Keep the pistol cocked. Put the pistol up to your ear. Pull the hammer back slowly (past the currently cocked position). Do you hear a tiny "click"? If so, that is your sear springing back against the hammer hooks as you relieve tension on it by over-cocking, and that is BAD. There should be NO sear movement at all (no "click") when you pull back on the cocked hammer with the safety on.

If you do hear a tiny "click", time to buy a new thumb safety - or weld up the lug on your current one.
