Cylinder Alignment / Timing

[julio793]

I checked the timing on my new "used" model 64 and though there is no movement of the cylinder in full lockup, when I look down the bore I can see about 1-2mm of the cylinder edge from about 12:00 to 4:00 (see attached photo). Is this something I will need to get fixed / can it be fixed?

Thanks!

If the barrel and cylinder are truly out of line, you need to let the factory fix it.

It does look a little out of whack.

A question: Was the photo (nice photo by the way) taken with the trigger fully to the rear, like you just dry fired it? This sometimes makes a slight difference in cylinder alignment.

You may want to recheck the alignment with the trigger pulled fully to the rear. This will be the cylinder's position when the pistol actually fires.

Thank you for the replies. Yes, this is with the trigger fully depressed. Also, it is this way on all of the cylinders. So while the timing is accurate the alignment is not.

BTW - photo taken with an iphone!

Is there any indication that it is shaving lead or jackets? If not, than it is very likely that the alignment could be within tolerances. Actually a little looseness in the lockup of an S&W revolver can aid in bullet alignment with the forcing cone.

I have not fired it yet. There does not seem to be any sign of excessive wear or damage around the forcing cone or the front of the cylinder, though I do t know if that means anything.

Pardon the pun, give it a shot with some lead bullets and see what you get for results (in/on the gun and on the target). Assuming it's really aligning like that when the hammer falls, it looks like it needs service. If there isn't slop in the lockup, the cylinder may be defective.

How old is the gun? S&W may warranty it, or may not, depending on its age.

AMEN! Shoot it with semi-wadcutter ammo and see if you get 'splats.' Looks like the O.P. is looking for something to worry about.

Thanks guys! Its s/n indicates 1975.

It's going to be a Father's Day gift so I just want to be sure I'm doing my due diligence. I'll just wait and see how it performs.

 

[JNewell]

FWIW, S&W is not going to cover a 1975 gun under warranty.

 

[julio793]

Yeah. I emailed them and they said to send it to them for an estimate (which will take six weeks) then I can pay them and they'll do whatever repairs are necessary (another six weeks). I'll just take it to a local guy and see what he says. Thanks!
