I currently own a Smith & Wesson 617-1 revolver with a 6” barrel. It has a 6 shot capacity. It is 100% mechanically sound, and 95% aesthetically. I bought it used about 7 years ago, and since I have use it mainly as a backup gun when deer hunting, and also for some small game hunting and some plinking.

I think I have not shot more than a 500 brick of 22’s through it. It is accurate and performs as expected. It weighs a hefty 44 oz. and measures about 11 ¾” overall length. Although not cumbersome, it does reminds it is with me when I am holstering it in the field.

A friend of mine is currently offering me to trade my S&W 617 for a Colt Diamondback revolver with a 4” barrel. I have not seen it yet, but he says it is in pristine condition. I have always been partial for vintage guns, and hence I’m considering to proceed with the trade, since I think that the Dback would be a better backup gun, due to it’s lower weight and shorter barrel length. That is, it will be carried a lot, and shot a little, that’s why I am considering it, but first I would like to address the following concerns:

1. Doing some research, I read that the Colt Dback had a tendency for developing timing issues in the revolver action, due its close tolerance manufacture. Although it said that this was mainly in the 38 special guns and not in the 22’s. Has anybody had experience/owned a 22 Dback that can confirm this issue?

2. Also I read a commentary where it said that when this gun was manufactured (mid – late 70’s), 22 High velocity rounds were not widely available as today, so this gun was made to shoot only 22 Standard velocity rounds (lead nose). And that by shooting in it 22 high velocity copper plated rounds, the additional pressure could damage the gun, first by producing timing issues, and then other problems. Is this correct?

3. The other issue, is that supposedly when the Dbacks where manufactured, Colt produced them in 22LR, 22WMR and 38 Special. And that they used the same gun barrels for the 22LR/22WMR guns thus using a .224” barrel to shoot .223” 22LR slugs (such as in the Ruger Single Six). Supposedly that is the reason why the Dbacks are not as accurate as other guns. Does anybody knows if this is right? If it is right, will the barrel tend to become leaded more easily?

4. Is is true that since the Dback has a 4” barrel, the gun will tend to foul and get dirty much more quickly than a 6” barrel gun? This due to its shorter barrel and closer gunblast to the revolver action?

5. Finally, do you consider this trade a good deal? Or is it better to keep the S&W 617-1 and forget about the Dback?

Any input will be greatly appreciated.

Thank you.
 
i sold a S&W 617-6 shot several months ago for 800.00 in mint condition and i think the dback is a ex revolver and i think its worth more that the 617. and it will do and shot any thing the S&W 617 will and in a handier package and i would make the trade in a heart beat if the conditions are the same. eastbank.

#1 Is not correct. The Diamondback was built on a more modern coil mainspring action, and does not suffer the problems the older V-mainspring action did.

#2 is not correct.
.22 LR Hi-Speed has been the norm, and widely available since I started shooting .22 65 years ago.

#3 is True. But it is not a deal breaker. The Diamondback will shoot better then most folks can shoot one.

#4 Is not correct. Barrel length has little or nothing to do with power fouling.

#5 It is a good deal, only if you think the trade-off in size and weight is a good deal.
But I imagine the Colt will continue to appreciate in collector value faster then the S&W will.

The Diamondback is no longer made and it is a fairly uncommon gun that IMHO will always have a following - not as great as the Python, but they are in demand. The 617, on the other hand, is a current gun; if you change your mind, you can always sell the D'back or keep it as a collectible and buy another 617.

I would do the trade , not because it is a better revolver , but because it will bring more money than the 617 .
 
AFAIK, High Velocity 22 Long Rifle was the norm by the 1950's, and quite possibly by the 1930's. The Diamondback could handle 38 Special +P perfectly well, so no flavor of 22 rimfire is going to strain it.

Personally, I would go for the Diamondback. I used to have a 38 Police Positive 4th Issue, which was the Diamondback minus the adjustable sights and all the other Python-type features, and it shot like a DREAM. Selling it was probably the biggest gun-related mistake I ever made.

PS - I have never heard of a 22 Magnum Diamondback. Were any really made?
 
Are you sure about that?
No. :eek:

Brain fade hit again.

Still, you aren't Gonna knock it out of time shooting .22 the rest of your life, unless you do a DA cylinder dump in 1.5 seconds every time you pull it out of the holster!!

As always, thanks for your reply. You save the rest of us much time by answering so well and completely. (esp. No. 4)

I'd do that trade in a heartbeat and shoot the beegeezus out of that Diamondback... A good model 617 is much easier to find than a good Diamondback...
 
Monetarily, the diamondback is more valuable and I believe will continue to climb in value faster than the S&W. A pristine diamondback .22lr is going for north of $1500 these days.
For a shooter, if you aren't concerned about the value, I'd stick the the smith. Parts are easier to find, and the factory support is still there. I don't know if Colt will be able to fix diamondbacks now, much less in the future.
I have not shot a 617, or a .22 diamondback, but I do know that the trigger in my diamondback .38 is not as good as my K frames. The Colt has a lot of stacking and a heavier pull.

That said, I'd make the trade, sell the diamondback, and buy another Smith .22 DA or two. Or just keep the Colt as an investment and buy another smith when you have the money.
I don't shoot my diamondback much at all because I'm concerned about the action going out of time and parts availability.

I would shoot the Colt first. If it fires through 25 rounds without a problem I think you have an excellent trade.

I am 100% with you on the idea of carrying a large revolver for .22 caliber purposes. I do not care for it either.

If the man is gun knowledgable, I am sure he knows the value of his revolver. If he is not gun knowledgable, and you consider him to be your friend, I suggest you tell him the value of his pistol. No pistol is worth a lost friendship.

Not to worry. If tip-top accuracy is required or desired, go to Paco Kelly's .22 ACU~RZR tool page. For a modest fee, it allows you a number of functions you may find desirable. With one or two quick taps per round, it will have any .22 WMR barrel chucking LRs out with match grade accuracy. And they do more.

He's a wonderful guy and fair.
 
I would do the trade in a heartbeat. Have always loved the look of the Colt Diamondback but nowadays couldn't justify spending so much money on one.
 
Sounds like you're not attached to your 617 and it would be wise to trade up in value while you can. Speaking for myself, I would not trade my 617 6" 6-shot for anything. Even if I made enough money to buy two of them I would probably go through a dozen more to find one that compares. Mine is strictly a range gun and never carried in the field. It does seem like too much of a good thing for that task.
 
Another vote for the Colt. The 4" Diamondback will be a featherweight compared to the 6" 617. Much easier to carry in the field.
 
Depends on the reason you want them; for shooting or for the investment.

If value is important, the Colt is the way to go, for obvious reasons ... especially if it's a straight-up trade.

If not, then I would recommend shooting the D'Back before you trade for it. You may end up not liking it as much as the Smith.

No shame in owning either of those revolvers ... or both, if you can swing it.
