Default 3914 hammer swap issue

I picked up a 3914 recently (tough to find in Ca.). I really like the pistol. In an effort to make it my own, I purchased a hammer from an auction site for a 5906.I believe it is an mim hammer. I had a friend install it for me, along with a set of checkered Houge grips. In the process, the side plate broke. he put everything back together.
The issue is that while the pistol works fine single action and decocts just fine, the douple action pull results in a late hammer fall. Sometimes it works as it should, other times the hammer falls late after the trigger is held back (Sometimes for a matter of seconds), and sometimes it seems to fall after pressure is released from the trigger.
I have a new side plate, and a new sear is on the way. The replacement hammer showed no indication of having ben worked on, I have no idea about the sear as it was a used pistol.
What should I have a gunsmith check for when I bring it to him with the new parts? (I am also having him install tritium night sights, not the Novak type)
Thank you,
Oscar Zulu

First concern would be a reassembly mistake.

However...

Had you not said the pistol was worked on, your symptoms sound like a broken drawbar.

They typically break in one of the rear corners and exhibit double action problems just like you described.

I switched out the hammer on my 3913 for one with a full spur so that it would match my 4505 duty pistol. Got the part from a department armorer. Had no problems. Good luck with your fix.

I have read advice from some knowledgeable people that recommended using a MIM sear with a MIM hammer, so hopefully the sear you have coming is also a MIM part.

With any luck, Fastbolt will see this thread and be along with some excellent advice as well.

Did this on a 3913, 4516, & 469. No problems with any of them. And as TercGen said, Mim, with Mim. GARY
