Hammer drops on unassisted slide racked into battery. ??? Good thing I found this out with a snap cap.  I was planning on sending off for a Kart barrel, mag well, and well, gutted for Ed Brown parts. What's the diagnosis? Sear? Thanks. |
| Have you taken it a part before? If so your sear spring may not be properly aligned. If you want all those parts installed, then send it off to Springfield Armory. Their Custom shop is excellent and if there is a timing problem with your hammer they will fix that too and it will be under warranty. |

Could be the sear, but chances are you bent the leaf spring too light, and now the sear is not holding on the jolt, or the leaf spring is not installed correctly (read you pulled the MSH without taping/pinning the grip safety pressed in and the left side sear leaf has slipped under the sear tab, and not on top of it). If the later, they you will need to pull the MSH out of the frame, the thumb safety and even the frame safety to reload the spring correctly. Once you reload the spring, install the housing back into the frame about half way up, then reload the safeties, followed by pushing the housing up the last of the way and installing the cross pin. The housing installed half way to start with will keep the leaf spring in the correct position. As for if you need to retention the spring, here is a primer but remember that sears have been tuned, and a lightened trigger/parts are being used to achieve the lighter pull in the write up. Without the lightened parts, if you try to set the spring tension weights this light, the trigger is going to dance back on it’s own during slide recoil to trip the sear, and you will end up with the hammer at half cock after lock up. With stock parts untuned used, go for a trigger weight pull of around 4.5 or greater to insure that the FCG will work correctly (no trigger bounce at slide cycle). www.brownells.com/aspx/NS/GunTech/NewsletterArchive.aspx?p=0&t=1&i=349 |
I think so but, glad he has your endorsement. Some of the smiths here in Phoenix are well, full of themselves. Don't listen, argue, then when I ask for advice they continue to discredit and argue and... Or freakin space cadets. I won't name names. It was him or Dave Stagg, who I know personally. Are they the only two sane 1911 smiths left?  |
