Main spring issue

After reassembly the gun will not dry fire. Now the spring/bolt will not fold out enough to pull the bold down and out. I fear the hammer was in the wrong position when the spring/bolt was reinserted. Any ideas?

You must be talking about a Ruger Mark III? If so, you are correct, the hammer was in the wrong position when you reassembled. Break it down again and Google Ruger Mark III disassembly/reassembly. You will find some good Youtube videos.

I'll troubleshoot a bit for you. Since I screwed up so many times trying to put this pistol back together until I got it, I feel a responsibility.

I assume you have it disassembled and the bolt and mainspring housing out. and that you have a stock pistol.

1. Safety off, magazine catch down.
2. Reach in back of receiver and push hammer fully back so bolt will slide in easily. Insert bolt. A little finger works.
3. Insert magazine, pull and hold trigger. Remove magazine; Keep holding the trigger.
4. Look in the back of the magazine housing in the frame and see the hammer at the top. Still holding the trigger, use a pencil, punch etc to push the hammer ALL THE WAY forward.
5. Release trigger.
6. Push the mainspring housing bolt stop pin through the frame till it seats.
7. Insert magazine, pull and hold trigger, remove magazine.
8. While holding the trigger, point the pistol up and slide the mainspring housing in to the frame until it almost seats.
9. Release trigger, point pistol horizontal and push the mainspring housing the rest of the way into the frame against slight resistance. If no resistance or great resistance, go back to step 4.

Analysis; The hammer must be all the way back for the bolt to insert, and all the way forward for the mainspring housing to seat properly. The pistol is pointed upward so the hammer extension (That little dangle you saw when you pushed the hammer forward.) can easily mate with it's notch in the mainspring housing.

If you need further help, Email me by private post.

Good luck.

PS; When you are pointing it upwards, just before you slide the mainspring housing in, it doesn't hurt to give it a little shake or 2 to be sure the hammer extension is dangling properly.

Back to the original posted problem--he cannot break it down again cause the mainspring assembly will not open (I think that's what the OP indicated.)

So, good chance the hammer strut is in the wrong place and MAYBE pointing the barrel down, pulling and holding the trigger, and banging the muzzle on a carpeted floor or block of wood will free up the hammer strut so he can open the MS housing lever and pull out the MS assembly and start over again.

Then again, if that doesn't work it's probably time to remove grips and hammer pin but that may be a job for Mr. Gunsmith.

Then again, the OP hasn't returned and probably got his answer someplace else. Don't you just love it?

Right....He may be gone. Hope it worked out.
I'm having a bit of trouble understanding the original post, but if the mainspring housing is jammed and won't come out or in, your advice to rap the muzzle to free the hammer forward should work. I found it better to put the muzzle on a magazine or pillow and smartly rap the back of the bolt with a plastic hammer or something similar that won't mar the finish.

Still here

Thanks guys, I have been traveling and not able to work on the gun. You are correct in that I can't get the bolt out because the spring will not fold out. I tried pointing it down trigger held and tapping on a carpeted floor but no luck. I believe you may be right in taking the grips and trigger out as a last resort. Going to try to play with it some tonight.....

I got it, thank y'all so much. I did what Kacher1 suggested again but used a block of wood and a little more force. It opened right up. Now, to reassemble again, and pay more attention to the hammer position!

Thanks again!
