If you feel you really must clean the inside of the action then instead of a total strip down just remove the grips and flush the insides with some home brew Ed's Red. The solvent and oil mixture will flush away anything inside left over from production, if there is any, and after the stuff drains and dries it leaves a light coating of ATF which is a pretty good protectant and lubricant.
You will find that the chambers on the 617 are tight and close tolerance "match" chambers. So don't be surprised if you find that cheap bulk pack ammo needs to be driven in with a hammer

A buddy just got his own 617 and found that some loose bulk pack ammo needs to be pushed into the gun rather forcefully. That same stuff was also hard to eject. But the more decently made ammo like CCI SV fits well. A good practice to use when buying ammo for your 617 is that if it does not come in the little packs with trays then it's likely not going to be well formed and will not fit the 617 well.
This also matches what I found with my own blued 17.
And plan on buying a .22 bore brush and fitting it to a short extension rod and keep it with the gun. You'll find that you need to brush the chambers out about every 50 to 70 rounds. You'll know it's time when the casings start to become sticky to eject. A pass or two of the brush down each chamber and you're back in business.
