I bought a used Dan wesson pm7 1911 the other day and I don't know what's wrong with it.

When the slide goes down sometimes the hammer does too. Letting down the slide after a fresh magazine is inserted, racking the slide, ect. The hammer will go down to "half cock" and it's bugging me.

What's wrong with my gun? Can I just replace a part to fix it? If you have any ideas for me that would be great. Thanks again!

Did you detail strip it or remove the mainspring housing?

No I don't consider myself qualified enough. Eversince I took apart my dad's 1894 winchester....

Sounds like a trip to the gunsmith if you aren't comfortable taking a 1911 down. I'm thinking its the sear thats causing the problem.

oops, i missed the "used" part in your original post.

i'm guessing that the original owner monkey'd with the sear spring, which is causing what you are seeing.

Give DW a call or E-mail them. Keith is their master gun smith and will be able to answer your question.

Have a gunsmith inspect the sear and replace the sear spring with a factory weight replacement.
Its a very common issue of just fine tuning the gun so don't get down on your new purchase, This is a very normal issue that happens alot.

Being how well made the gun is you may ask him to install a good Cylinder and slide sear spring and hand adjust it and also fine tune it with files to get the smoothest operation possible.

Could be the sear angle and or hammer notch have been goofified by a similar goof.

Replacement of both along with the sear spring may be in order. Best to send it out to get it looked at. Not a terrible fix for most gunsmiths will cost a bit though.

Sounds like a spring or sear.

If someone goofed up your sear and hammer, now would be a good time to upgrade to Wilson parts. It's fairly inexpensive, and easy for any competant smith to do.

Can anyone recommend any smiths? I do trigger jobs myself with the Ed Brown sear tool. Maybe Keith at DW can check it out for you.

Either botched engagement angles on the sear/hammer from a trigger job, or the far left leg of the sear spring needs to be bent forward ever so slightly.

Blessing in disguise. It's called hammer follow if you want to google it to get more info.

I think it's a blessing because it gives you an excuse to get a good trigger job done.

Be careful though, it's potentially a step away from doubling or going full auto.
