Mark III doesn't fire for first trigger pull

[Pill Form]

I bought a 22/45 Mark III brand new. Put hundreds of rounds through it with only one failure to eject, and one failure to cycle. This is my first firearm purchase, by the way.

I decide to do the take down and clean it for the first time. I had a little trouble taking out the bolt stop pin, but I thought it all went fine.

Now when dry firing the trigger will only engage after the second pull. For the first pull, the trigger will go all the way back without resistance.

So did I put it back together wrong, or bend something? Any input is appreciated.

Browning Buckmarks don't do that.

The mistake was to "take it down and clean it" unless it was dirty enough to stop functioning properly.
Over the last 25 years, I've had at least 2 dozen Ruger 22 pistols(either personally or through the shop) and shot all of them some or a lot. Maybe 3 or 4 have been taken down and cleaned. The chore gun I carry on the trapline finally got dismantled after I dropped it in the creek but prior to that it had fired thousands of rounds w/o cleaning.
A Ruger 22 pistol is like a vehicle engine(IMHO), they're not something just anyone needs to take apart every time it's used.

You bent or did something to the disconnector (which is also the trigger bar) and it is dragging on the side of the frame inside. It has to be free to move up and down. When you pull the bolt back it pushes the bar down out of engagement with the sear. It is supposed to pop back up under pressure of the spring under the plunger in the trigger. So you either did not put the spring and plunger back into the trigger correctly (not likely) or you bent the draw bar, and when the bolt pushes it down, it is staying down until you jiggle it by pulling the trigger and then it pops back up.

Another possibility is you got the spring on the sear in wrong (if you took that out) Most likely is the bar.

You will dramatically shorten the life of your Ruger if you keep taking it apart all the time. There is no need for that more than once a year, and maybe not then.

Thanks for the responses so far.

Just as a quick update if anyone cares, I fired 150 rounds through it and I did have this problem sometimes on the first trigger pull. The pistol cycles fine, and each round in the magazine after the first will fire without problem. It's not a huge deal, but I think I'll probably at some point take it to a gun smith or maybe send it to Ruger for repair if I can.
