FWIW installed a Wilson spring kit too.. Three of the first 10 rounds fired. Went back to the original hammer spring and the gun was 100%

There is no single action with this hammer.

Glad you got it back together and running. Had to snicker at the lost hammer. Just when you think nothing else can go wrong...
What kind of speed loaders do you have? They look good. Wonder if the make them for my 6 shot 617.

Loaders are "Speed Beez." They are as slick as they look...

I have 3 of these. 2 6 inch and one 4 inch, all 10 shot. I've had zero issues with them. They've been 100% reliable with the CCI ammo I've used in them. The 2 6 inch guns are used for steel plate league shoots and have had many 100s of rounds through them. Great guns.
Dennis.

A Pair and a Spare! Good deal!

Stan.... thanks for posting photos of parts installed. While not about to swap out original clockwork of my old, college protein gathering K-22, I hope to see some range reports with your speed-shooting lockwork, with your impression of stock vs. aftermarket lockwork. David Bradshaw

Did the new hammer require any fitting? I too have a 617 with reliability issues and have been considering this same fix. Mine runs 99% with MiniMags, crap shoot with Federal Automatch and Remington Goldens.

Check1) STRAIN SCREW. Firing pin INDENT grows weaker as strain screw is backed off. May be loose, or set too loose by someone wanting to lighten pull. 2) FIRING PIN PROTRUSUION. 3) ENE SHAKE.

Mine runs 100% with stock hammer spring and the Apex Mass hammer. Not so good with reduced power hammer spring. Am running the Cylinder & Slide extended firing pin and a Wilson reduced power rebound spring. In the first few 100 rounds mine had a few issues with trigger return. The 100 rounds today ran fine. Yesterday had two failures to return in 100 rounds. A disassembly is planned soon to polish the rubbing spots.
FWIW make sure the strain screw is tight. The cautions you read about it have to do with the screw wanting to come loose from firing the gun. Have had friends slap a little loc tite on theirs.

David Bradshaw I just happened to order a new strain screw from Brownells last week on the recommendation of a fellow shooter. The new one is .05 longer than the one installed. The one installed was apparently shortened when I sent the gun off for action work many years ago? I installed the new screw today and test fired with CCI and Remington ammo. 100% function! I'd like to test fire with some Federal still, if I can find any. How does one check firing pin protrusion? Replacing the FP with a Cylinder and Slide extended version, like the OP did, seems like a cheap insurance policy for further guaranteed function.

Many years ago----decades----I ran an experiment on S&W mainspring tension and behavior of the STRAIN SCREW. Old mechanics at S&W, including guru Al Plaas, said nornally the strain screw is turned against its seat; Mainspring adjustment is made by filing (shortening) the strain screw. Armorers were taught this as a hedge against the screw backing out on service guns, to cause misfire. Target shooters commonly violated the tight screw principle, and this includes silhouette shooters loading full tilt loads in quantity. Sketchy ignition came to the unwary and those who like the lower limit of reliable ignition.
My own experiment with the strain screw backed off hard-seat show an unsecured strain screw loosens SLOWLY. My experiments included M-29 .44 Mag and M-19 .357 Mag. Routine cleaning includes checking all screws: rear sight leaf, sidepale, strain, and on earlier guns, the cylinder stop plunger screw. I could feel in double action dry fire & live fire a reduction of rebound tension. Reduction in rebound tension is considerably more difficult to detect in single action; I trusted my perception in double action.
S&W offered a LIGHT REBOUND SPRING to reduce DA pull without compromising rebound. Of course, someone undisciplined in the coordination of double action fire may be unaware that TRIGGER RESET requires FINGER RESET.
The old S&W mainspring is a drop forging of extreme quality, reliability, longevity. I have seen many springs of newer manufacture fatigue while those old springs carry on. “New” does not automatically spell “better.”
To experiment with mainspring tension via strain screw is perfectly acceptable for serious marksman & markswomen. There is no difference between silhouette reliability, trail reliability, and survival reliability. It is a vanity to draw distinction. The Firing Line is a valid place of experiment. SHARPSHOOTING does not develop without personal experiment. David Bradshaw

A tip to train double action fire...
To anchor LINE of SIGHT, squeeze trigger straight back into your eye. Release trigger same speed as squeeze. Deliberate squeeze & release tones tendons, muscle & mind.Dry fire practice locks LINE of SIGHT. Smooth reset sets up the following shot. David Bradshaw
