Taurus cylinder gap

I've got a Taurus 669 .357 revolver that I've had for about 10 years. I checked the cylinder gap on it the other day and noted that I have to pull the cylinder backwards by hand to get any gap at all. It takes very little pressure to pull it, and when I do I get about .010" gap.

Timing is good, the cylinder rotates freely when firing, and it doesn't spit any lead. Should I worry about this apparent "end shake" and try to get it fixed, or just live with it? Am I misreading this, and it's not end shake at all, but something else?

Heck, maybe it's an excuse to go get a 686... :)

The SAAMI recommended maximum is .012", your Taurus is pretty close. I like my bbl/cylinder gaps closer to .004" (or less). The end shake should be easy to repair.

Even though it doesn't exceed the max, I would git r done :)

The large end of cylinder gap is costing you power. If as you say all the other indications are ok then you only have to be concerned with loosing say 200 fps on the warm loads. If you only shoot lite & moderate loads then don't worry about it.

Any excuse for buying a new toy is good.

I'm reasonably competent inside a gun myself, having resprung several revolvers, installed a couple of rifle triggers, and done lots of work on semis, including fitting triggers on 1911s. I've had the crane apart on this particular Taurus.

Would eliminating the end shake and reducing the gap be something that I might be able to do myself? I believe it's basically the same thing as a K frame S&W (the frames are identical, not sure about the internals, as I've never taken a Smith apart). Brownells for shims, etc? Any place online that might have instuctions?

Thanks,

get a good book first

Endshake is solved fairly easily by yourself if you have the knowledge. I would suggest getting a good book on revolvers and reading up on it before trying to fix it.

With the two being as similar as they are, this one should give you all the necessary info to take care of endshake. You might look to a video from AGI, they sell the armorors tape for the S&W as well, but I would ask them if it gives info on how to cure endshake before ordering it. Good luck with the project.
