Check to see if magazines insert and drop out cleanly. This HK USP40 Compact passes the test.

Get some light on the other side of the gun, so you can look through the gap between barrel and cylinder. Hold the hammer back with your thumb until the bolt drops, and then rotate the cylinder, watching the gap. If you examine enough guns, you will find some that actually touch the forcing cone of the barrel. This is unacceptable; the cylinder will bind, the trigger pull will become uneven, hard, and “grating” as your finger works to force the cylinder past the bind point, and eventually the gun will lock up and stop working. On the other end of the spectrum, you may see a barrel/cylinder gap so wide that you could probably spit through it without touching metal. You can expect poor accuracy and nasty side-spit from such a gun. Reject it unless the seller is willing to pay for the repairs to bring it up to spec.

If the cylinder comes closer to the barrel on some chambers than others, the front of the cylinder is probably not machined true. Most experts would pass by such a revolver.
