I have a Springfield loaded, that has following issues (the hammer follows the slide when dropped with the slide stop) I finally mustered the courage to completely strip the gun (not as bad as I thought) and the sear/disconnector look fine, so I'm thinking its the sear spring. I dont know how many rounds the gun has through it, but I ordered a new ed brown sear spring.
So my question is, am I missing anything? what else should I look for? Will my gun shoot again with this $8 part? edit: also the only way I could get a good function check after reassembly, was with the sear spring on top of the disconnector, which sits on the back of the trigger, is that correct? |

Bad parts can look good if you do not know what you are looking at.
You can try and bend the sear spring you have now. If hammer follow is fixed then you good to go. If bending the sear the spring does not solve your problem then the sear, hammer, disco, maybe the problem, one or all. Pics |

You can have hammer follow through for a variety of reasons. It can be as simple as the sear spring not being properly tensioned, to a combination of probelms that are harder to diagnose. If course, an over the internet diagnosis is not always the best, but there are some things you can look at. Also, it would be helpful to know what Springfield gun you have, as well as any mods to the gun with regards to springs, fire control parts, grip safety, mainspring housing parts, etc.
Check this link for a thread that is currently on page six of this forum. It addresses some of the common causes of hammer follow through, as well as some more obscure causes. http://www.ar15.com/forums/topic.html?b=5&f=49&t=77247 |

Its a stock Springfield loaded. I looked over all the parts, and compared them to pics online and they all seem to be alright. and from what I have seen/read I think and hope its just the spring tension. When I get home from work I'm going to rebend the hell out of it to see if the following stops. It also has an adjustable trigger, which I think im going to back way out to see if that helps as well

Quoted:
well I bent the far left finger on the sear spring, and it seems to have cleared it up. I'm going to replace the spring with the new one I ordered from brownells anyway. Anyone have any theories as to why the spring deformed after only 1kish rounds? Marginal fitting to start and even a tiny bit of relaxation in the spring. It could also just be a bad spring. If the temper is not uniform the softer spots preferentially take a set reducing the spring force. |
