The revolver check that catches timing issues before you buy

Timing problems on revolvers are one of those things people treat like black magic, but you can catch a lot of them with a simple check before you ever hand over money. You don’t need to be a revolver wizard. You just need to understand what “timing” means in plain terms: when you cock the hammer or pull the trigger, the cylinder has to rotate, lock into place, and line the chamber up with the barrel at the right moment, every time, on every chamber. If it’s late, inconsistent, or sloppy, you can get spitting, shaved lead, poor accuracy, ugly wear, and in worst cases, real safety issues. A revolver can feel smooth in the hand and still be out of time—especially if someone polished it, lightened springs, or ran hot loads through it for years.

The easiest buyer mistake is only checking one chamber. They’ll open the cylinder, spin it, check that it “locks up,” and call it good. Timing issues often show up on specific chambers first, and they can be subtle until they aren’t. The check you want is simple and repeatable, and it tells you whether the gun is locking up correctly at the moment the hammer falls. You’re basically verifying that the revolver isn’t relying on luck and momentum to line things up.

The check: carry-up and lockup on every chamber

First, make sure the gun is unloaded. Then close the cylinder gently and work one chamber at a time. On a double-action revolver, slowly cock the hammer in single-action and watch for “carry-up,” which is whether the cylinder rotates fully and the bolt (cylinder stop) locks into the notch before the hammer reaches full cock. You want to hear and feel the cylinder click into lock before the hammer is all the way back. If the cylinder is still moving, or it only locks right at the very end, that can be a sign of late timing.

Now do the same thing in double-action—slowly. This is where a lot of timing issues show up. Slowly press the trigger rearward and feel for the moment the cylinder stop drops and then pops back up into the notch. The cylinder should be locked before the hammer drops. If the cylinder is still rotating as the hammer is falling, or if it feels like it “snaps” into lock at the last instant, that’s not what you want. A revolver should not be trying to finish its alignment at the moment it fires.

Do this for every chamber. Not two. Not “seems fine.” Every chamber. Mark them mentally as you go so you don’t lose your place. Timing problems can be consistent across the cylinder, or they can show up on one or two chambers first because of uneven wear on the hand, ratchet, or cylinder stop notches.

The push test: checking for bolt engagement without lying to yourself

Once you’ve confirmed the cylinder is locked at full cock (single action) on a given chamber, do a gentle push test. With the hammer cocked, lightly try to rotate the cylinder back and forth with your fingers. You’re not trying to muscle it—you’re checking how solid the lockup is. A little movement is normal on many revolvers, especially older ones, but it shouldn’t feel sloppy, and it shouldn’t rotate enough that the cylinder stop looks like it’s barely hanging on.

Then do the same test at the end of a slow double-action press, right before the hammer would fall. This is important because some guns feel okay in single action but show weakness in double action. If the lockup feels inconsistent from chamber to chamber, that’s a clue. If you find one chamber that feels noticeably looser or locks later than the others, that’s where timing wear is starting to show.

Also watch the cylinder stop itself. If you can see it not fully engaging the notch or if it looks rounded off and shiny like it’s been slipping, that’s not a small cosmetic issue. That’s wear in the parts that keep alignment honest. Sloppy lockup isn’t always the end of the world, but it’s never a “pay top dollar” situation.

The visual clue: off-center drag lines and stop notch damage

Most revolvers will have a drag line. That alone doesn’t mean anything. What you’re looking for is the character of the drag line and the stop notches. If the drag line looks unusually deep, uneven, or if you see peening and deformation around the cylinder stop notches, that can indicate the cylinder stop has been slamming into the notches hard or at the wrong time. Timing issues and rough action work often leave those fingerprints.

If the notches look rounded, battered, or chewed up, that can mean the bolt is popping up early or late, or the gun has been fanned, slammed, or otherwise abused. It can also indicate someone tried to “slick up” the action and didn’t do it correctly. You’re not buying a museum piece here, but you are trying to avoid a gun that needs immediate internal work just to be safe and consistent.

The spitting clue: forcing cone and top strap signs

If you can inspect the forcing cone area and the front of the cylinder, look for signs of spitting or shaving. Lead or jacket material can show up as roughness, pitting, or uneven wear around the forcing cone. Again, not every mark means timing is off, but timing issues often show up as material being shaved because the chamber isn’t perfectly aligned at the moment of firing. If the forcing cone looks battered, cracked, or unusually rough, that’s a bigger conversation.

Check the top strap above the barrel-cylinder gap too. Some flame cutting can occur with certain loads and certain guns, but heavy cutting, especially on a gun that’s supposedly “barely used,” is a clue that it’s seen a lot of hot ammo. High round counts with heavy loads can accelerate timing wear. A revolver that’s been fed a steady diet of hot loads can be tight in some ways and worn in others. Timing and lockup are where it often shows.

Why this check matters for buying used

Revolver timing work isn’t always cheap, and it’s not always simple. Sometimes it’s a hand. Sometimes it’s a cylinder stop. Sometimes it’s a ratchet. Sometimes it’s a combination of wear that requires fitting parts properly, and “fitting” is the key word—revolvers aren’t always drop-in repair guns the way some semi-autos are. If you buy a revolver with timing issues because you didn’t check it, you might be signing up for a gunsmith bill that eats up whatever “deal” you thought you got.

The good news is, most revolvers that are in decent shape will pass this check easily. You’ll feel a consistent carry-up, consistent lock, and similar lockup on every chamber. When you find a gun that doesn’t, it usually stands out once you know what you’re feeling for. Don’t ignore that feeling. A revolver can be pretty, smooth, and still be wrong in the places that count.
