sslav Posted March 15, 2010 Share Posted March 15, 2010 I bought this gun new back in 2005. I had put maybe 200-300 rounds through it back then and its been sitting in the safe ever since. Recently I got this crazy idea that I should shoot a revolver in competition. So a couple of weeks ago I started to dry fire it semi regularly and fired another 100 rounds through it. Last night in the middle of dry firing the gun started behaving erratically. Sometimes pulling the trigger would cock the hammer as normal and sometimes it would only rotate the cylinder. I took it apart and found that a tiny spring that is a part of the hammer assembly broke. Looking at the diagram I believe it is called a sear spring. Is this a common occurrence with this model?

Toolguy Posted March 15, 2010 Share Posted March 15, 2010 Those usually last the life of the gun. Probably had a bad one. Link to comment Share on other sites More sharing options...
Carmoney Posted March 15, 2010 Share Posted March 15, 2010 The sear springs on the newer MIM-guts Smith revolvers are tiny little coil springs that are held in place by simple detents on the hammer and the sear. I've never seen one break. The more common problem is that sometimes people go messing around inside the gun and remove and replaced the sear spring carelessly, allowing the spring to be bent or squashed when reinstalled.

bikerburgess Posted March 18, 2010 Share Posted March 18, 2010 mine did not break but I did get it bent up, like Carmoney said messing arround in the gun. Mike Link to comment Share on other sites More sharing options...
Patrick1981 Posted December 17, 2012 Share Posted December 17, 2012 On Midway Italia I cant' find the specific MIM hammer sear spring, I look it only on Brownells, but both have a " bolt plunger / sear spring " double use, that is too long for a MIM sear spring. I think is the spring for the forged hammers, with pinned sear, right ? On two of my 686 the spring are slightly bent Link to comment Share on other sites More sharing options...
BlueOvalBandit Posted December 17, 2012 Share Posted December 17, 2012 This "should" be it. http://www.brownells.com/handgun-parts/trigger-group-parts/sear-parts/sear-springs/sear-spring-mim-hammer-prod14712.aspx I got mine from midway, it was the correct size, but I can't find it anymore.

Bubber Posted December 17, 2012 Share Posted December 17, 2012 I just changed the one in my 627 out this last week. It had broken with about three coils down. I had an old spring from a L frame hammer. I shot a little more than 300 rounds on the 627 by then. Maybe quite a bit more. later rdd Link to comment Share on other sites More sharing options...

Luv2rideWV Posted January 20, 2013 Share Posted January 20, 2013 I agree with the above posts; we usually mess these up during assembly/disassembly. If I might make a suggestion, order a few of these and keep the spares in a safe place. If you work on guns, you will eventually lose or ruin something small and delicate. Nothing sucks worse than crawling around in the kitchen floor in the wee hours of the morning looking for a spring that small. Link to comment Share on other sites More sharing options...
alecmc Posted August 5, 2013 Share Posted August 5, 2013 this sort of goes in the catogory of this thread... ( didnt feel like starting a new thread ) The MIM sears are the same for J / K / L / N / X frames correct? looking for n frame sear, only mim one i found was this : http://www.brownells.com/handgun-parts/trigger-group-parts/sear-parts/sears/sear-for-mim-hammer-sku940000505-14709-34186.aspx says for J FRAME... I'm pretty sure they are all the same, but since I dont own any j frames I cant say first hand... Looks the same. confirm ? Link to comment Share on other sites More sharing options...
Gregg K Posted August 6, 2013 Share Posted August 6, 2013 If you go to the S&W web site and look up the part listing for a MIM sear for a 625-6 the part number is 215350000 that is the same S&W part number that is listed in your link so it would be the same part. http://www.smith-wesson.com/wcsstore/SmWesson2/upload/other/RevPartsList_Retail.pdf Link to comment Share on other sites More sharing options...
