With magazine removed, hammer cocked, and safety off, the trigger is pulled on an empty Browning Hi-Power. Hammer does not move, demonstrating that magazine disconnector safety is functioning as designed.

In a test that will make you cringe, unloaded pistol begins at slidelock with finger on slide release lever…

…and the hammer remains cocked as the slide slams forward. This shows Kimber Custom .45’s sear mechanism to be in good working order. However…

…if the hammer had “followed” slide to the half-cock position as replicated here, gun would need repairs before being worthy of purchase.

A less abusive test for hammer-follow on an auto is to hold it as shown and repeatedly flick the hammer back with the free hand thumb.

Push the cylinder back and forth; front to back and vice versa. A lot of slop means excessive headspace. Particularly with a big-bore or a Magnum, it may be a sign that the gun has been shot so much it’s approaching the end of its useful life. A good gunsmith can fix this with some cylinder shims, however.
