Got my 27-2 today! Then broke it!!!

[Snapping Twig]

I have a 28-2 that was shooting way low with my reloads @ 1200fps, so I went to Numrich and got a rear sight assy from a 29 since the blade was taller and once I put it on, there was a smaller gap under the rear sight and it shoots to POA..

Very nice! Your price was about the norm around here for a nice Model 27.

I really like Muley Gil's idea of using a plastic bag for sight disassembly.

Others on here have made this suggestion before me. Just trying to pass on good advice.

Parts came today!

Holy cow, you're not kidding! I'm fairly mechanically inclined, and I'm used to working with small parts and assemblies, but that mother had me uttering words I was never taught in catholic school! Muley Gil, thank you for your suggestion. Based on your advice I was working inside a gallon freezer bag, and was glad I was no less than three times! Did finally get it all together though.

Just need to make a spanner to finish the job, then we'll be all set.

Another assembly suggestion..... when you tighten the nut prior to staking, make sure you back it off about a quarter turn before staking it to the screw. If you get the nut too tight the screw/blade assembly will not turn freely.

What I do when changing out a rear sight blade is remove the entire sight and then put it in a small vise. I put the spring and plunger in the screw head, depress them with a small metal 6" ruler and then slide the blade assembly into the sight body.

The vise acts as that "third hand" that we all need at one time or another.

Well its a good thing I ordered TWO new windage screws!

What wasn't clear to me in the videos etc. was that when you stake the end of the new screw, the staking needs to be forced INTO the slots of the spanner nut, locking it in place so it spins when you turn the windage screw. The first one I did I didn't do that, I just expanded it enough so that the nut couldn't come off the screw. So, when I went to test blade movement, I just turned the screw in until it sheared again. Then I examined some of my other guns and saw how the nut spins with the screw. Second one worked perfectly!

You learn something every day!

I had to replace one of those little *@#$ screws about a month or so ago. I last did it about 25 years ago when my eyesight was better and my fingers more nimble. I lost two springs and one plunger before I gave up and got out the 1 gallon freezer bag... almost lost another plunger inside the bag!. The bag-wrapped vise sounds like a great idea.

Now...to the range. Keep in mind, for a right-handed shooter, groups that are low/left are usually not the gun.

That usually requires adjustment of the nut behind the gun.

YMMV.
