Took my 617 4" barrel ten shot out for it's first visit to the range. Single action it seemed okay but double action was almost impossible. I had to pull so hard it was very difficult to stay on target. Is there a kit for smoother action? Is this a factory fix and warranty issue. I understand the safety issue of the exposed hammer, but this is just a range and plinking revolver for me. Any advice?? Thanks
John

But, only attempt a trigger job if you feel competent that you won't ruin your revolver. Get experience before just attacking it. 22 RF does take a heavier trigger to reliably set off the primers. Never replace the mainspring on a 22RF, unless you expect misfires.

I was a jeweler at one time and am fairly mechanically adept and have a buffing wheel, but I'm no gunsmith. It's a new revolver so I doubt it's an old lube issue but will clean it as advised. Dumb question to follow. Can you use spent shells to check out the action by dry firing? I know it sounds silly but I travel a lot and I don't have a range very close by.

I do all the time... and also use these:
Crown Bolt #4-8 x 7/8 in. Yellow Ribbed Plastic Anchor (100-Pieces)-54772 - The Home Depot

Red flag alert!! You are strongly advised not to apply any power tool to a SW revolver. Ever. After cleaning, try putting about 1000 rounds double action through your new revolver, then reassess. After some experience and a great deal of research, you could consider taking off the side plate for a look inside. Have fun breaking in that new piece!

Remember NEVER to dry fire a .22 caliber rimfire firearm. The firing pin can impact the edge of the charge hold and damage the cylinder or firing pin.

OP, you are at least the second person in the last month to note a near impossible DA trigger pull on a brand new M617. What's up with that?

There are some good videos on YouTube showing how to do a standard "fluff & buff" trigger job. It's not hard. A stone, some metal polish, some moly grease, maybe some 1000+ grit sandpaper.

And their are companies that sell reduced power rebound springs and main springs. If you want to play around with those.

Definitely avoid any power tools. It can all be done by hand. Even the very bests high dollar gunsmiths do it by hand.

I had a new 586 open a few months back. It had a horrible hard pull, over 12 pounds. The mainspring was very stiff and appeared to be thicker than previous mainsprings I have seen. I wonder if this is something new? I didn't think to measure it, just replaced it and sent the original spring back to the owner.

I bought a 4" 617 a month or so ago. The store had two of them, so I got to select the "pick of the litter." Both were very nice (great lock-ups, straight barrels, and nice double action trigger pulls), so if it's a factory issue, it's hit and miss.

Mine too was really tough to pull DA. Last evening at the range I installed a Wolff 13# rebound spring and backed the strain screw out 1/2 turn-major improvement! Fired 100-150rds and she was smooth and flawless. Upon returning home I removed the strain screw and gave it a little drop of blue Loctite and tightened it up and then back 1/2 turn.

These days the insides of new revolvers are dry as a bone. I always pop off the sideplate, and clean and lube the innards with Gunslick graphite grease. Then run a couple thousand rounds through it!

Makes quite a difference.

If you're familiar with revolvers and what a reasonable double action trigger pull feels like...

Double action triggers should not pull as you describe. That's a warranty issue if it's truly that difficult

If you're not familiar get it into someone's hands who is.

A few simple things can be done to (greatly) improve a properly functioning 617 trigger.
