Won’t cock on last round.

Ruger Mark III 22/45 with VQ trigger and Mark II bushing. Naturally removed the Magazine Disconnector and spring, also removed the LCI lever but not the plastic piece that covers the hole.
I you load 2 thru 10 rounds the last round will chamber but the gun dose NOT cock. Thought it was a magazine problem and tried a friend’s magazines with same results. Change the Trigger Spring and Plunger back to stock did not make a difference.
This started when I made these changes.
Any Thoughts?

When was the last time you did a detail clean of the gun?

What ammo are you using? Std Velocity, High Velocity, Sub sonics

You say not cock, like the trigger is not resetting? You may have the pre travel set to tight, back it off 1/8-1/4turn.

Did the detailed cleaning when I put the new parts in.
Yes trigger is not resetting. I had both High and Standard Velocity, made no difference.
Forgot about the screws. I will back them off and get back.
Thanks Dave

OK.
Backing of the trigger screws cured the problem. I set them on the bench; dry fired a few times and went to the range. Did not even take the Allen Key with me to the range. Never be without it now.
After the first 9 shots out of 10 I thought it was something else NOT the screws.
Still can’t believe it was only the last round every time.
Well it works now and that’s all that counts.
Thanks Dave

Don't for get to LocTite it in place so it doesn't move on you.

A lot of folks forget to Loktite the screws and they end up walking on them later. Wick in some blue Loktite and you should be good.
