Difference between a Model 17 -2,-3,-4

[ebrem]

Hello

I am new to revolvers , so I would like to ask for some advice.
I have a chance to buy a Model 17. I also have choices of a -2,-3, and-4.
Each are equal in condition 96%-97%. All have the target trigger and target hammer.
1. Is one model varient better than the other?
2. What is the better choice knowing that they are equal in condition.

I am not using this to collect, I plan to shoot it.

Thank you in advance for your response.

The dashes are engineering changes. "Better" is subjective.

-2 the 4th screw was eliminated from the front of the trigger guard.
-3 relocated the rear sight leaf screw.
-4 moved the gas ring from the yoke to the cylinder.

From a collectors standpoint the -2 and the -3 would be somewhat more desireable. From a shooters standpoint the -4 would be more desirable because of the gas ring move.
Hope that helps some.

Difference between a Model 17 -2,-3,-4 (-5 added)

hello

One more question.
I alos have an opportunity to pick a -5 Would this varient be BEST for shooting compared to the -2,-3.
The condition of the -5 is 95%.

Again thank you all for your responses.

Good information. I've got a 17-3 and was wondering what the
advantage would be for moving the gas ring from the yoke to the cylinder in a .22 revolver?

As you know .22LR ammo is noted for being dirty, but the change was done on all models and calibers.

The purpose of the gas ring is just what it says. It was to divert gases, unburnt powder, lead shavings and junk away from the cylinder and collar so as not to cause the cylinder to bind up. With it on the yoke this debris still got around it somewhat and into the cylinder and caused binding problems, so the -4 moved it to the cylinder to do a better job. That may be oversimplifying it somewhat, but it'll have to do.

Thanks Dick. I've always wondered about that particular change when they upgraded the various models.

If condition and price are about equal, and you want to shoot it a good deal, go with the -4. The gas ring move really does help reduce cylinder bind compared to the older K-22's. The -5 started in 1988 and offers no real shooting advantage as the updates were the "radius stud package and new yoke retention system'' -both done to ease production fitting.

As others have mentioned-pick yours then let the forum members know where the others are.

Hi, Dick. SCSW is clear on this, but my -3 has the gas ring on the cylinder. Would this be one of those examples in which an earlier, unsold frame was salvaged and then-current parts were used to complete the gun?

Andy it's hard to tell. It could also be a transition gun, which most likely the case. It's not very likely that a newer yoke and cylinder was replaced after it left the factory 'cause that's not an easy thing to fit. Probably a late -3 transition gun.
