S&W model 67

[habanero]

My father gave me a S&W revolver, and I just discovered it is a model 67. He is the original owner, and says it only has had about 500 rounds put through it. I tried some less expensive ammo in it, and experienced a ton of misfires. This was corrected with better ammo, but the indentation on the primer is more shallow than another S&W .38 that another guy at the range had. Is this something to be concerned about, and if so, is there anything that I can do about it?
I did a trigger job on my .22 rifle due to the help on this site, and I am wondering what people do to modify their revolvers. It looks like people replace the springs using WOLFF products, so I guess thats the first thing I will do, so I can decrease my trigger pull. Any more ideas would be appreciated.
Thanks!

On the front of the grip strap you should see a screw. Make sure it is tight. That should take care of your light hits unless somebody got to it with a file. Wolfe spring kits are quick and easy and recommended. Now while you have the side plate off look at every piece that has a riding surface on another. Stone or polish EVERY piece that has a bearing surface to an even mirror gloss removing as little metal as possible. Lubricate with a good lubricant, and reassemble. Do this by hand and put the dremel tool away. More guns have been screwed up by a dremel tool than anything I can think of.

Where can I find some instructions for the takedown (disassembly/reassembly) for this gun? I have looked on S&W website, but their owners manual doenst have this info. I have also looked online, and all I could find was this website http://www.tpub.com/gunners/61.htm , which has like 6 steps, but doesnt talk about springs.

Sounds like you are just getting started with a lifelong love affair with guns!!!! Try the 'google.com' search engine on your computer and search for firearms assembly/ dissassembly. Also at amazon.com. I don't know of any free ones on the net, but invest in as many of the assembly/disassembly books on as many differant types of guns as you can. They ARE worth it.

OK, I got the two WOLFF springs, the one trigger spring, at 11#, and the reduced #2 mainspring. That was quite an adventure taking down this gun (especially since I really didnt have any instructions), but I was successful. The trigger pull is extreemly light in single action mode. Double action trigger pull varies depending on how tight/loose I adjust the mainspring screw. I need to take it to the range to see how loose I can have it, while still providing enough force to ignite the primer. Sure am glad I made it through this, cause this gun is gunna fire much nicer than before!

Just a tip that when you remove the screws holding the sideplate, tap on the frame with a nonmarring hammer to loosen the sideplate. Never pry off the sideplate with a tool. I would have also gone with factory rated springs from Wolff as you may get misfires with lighter springs. ;)

I took my S&W out to the range today, after replacing those two springs (Wolff mainspring and 11# trigger spring). I loosened the mainspring screw adjustment about 2 full turns and started there. That was too light, and the round did not fire. I turned it in 1/4 turn, and that was still too light. 1/4 turn more, and that was perfect! I then shot another 24 rounds, single and double action, and every round fired. Man, this trigger pull is very light, especially in single action mode. Its like a hair trigger. Sweet! After shooting this gun, my friend busted out his Taurus .357, and the trigger pull on that was terrible in comparison. It is amazing what $15 can do for your gun! Now if I can hold the thing still when I shoot. ha ha ha
