Model 14. Shooting 2.8 BE,Zero 148 HBWC's.  My rear sight is as low as it can go. I'm OK holding sub 6 at 25 yards.  I ran outof 148's, found some hard cast 158 gr SWC's. Over 2.8 BE they shoot really high, like hold S6 and they hit above the black.  Do you think I could adjust POI with a load change? I don't know if more charge would equal a higher or lower POI, or if I could change POI that much.  The other option is a different rear sight blade. I did change it to a "Target" version with a deeper notch. Deeper notch means higher sight blade= have to crank it down all the way.

Notch depth will do nothing.
You need a lower rear sight blade, or a taller front blade.
Both are available


Surprised not centered with that load.

I'm meaning the notch is deeper not by deepening the notch from the bottom, rather making the blade taller. I love this sight picture though..38 spl point of impact/load question Img_1712

Blade needs to be lower to shoot lower


Is that a new one? Doesn’t look right.

Newest k frame?

Jim, it's a 14-3.  I found this blade either at Brownells or another online shop. I was searching target blades and found this one a couple years ago.  and yeah, the whole thing sits a little higher than the original blade.

Blade looks like a Jack Weigand replacement blade for standard S&W adjustable sights. Cannot tell 100% without seeing side view. Weigand rear blades are available in different U notch opening widths. I wasn't aware they were available in different heights.

I don't think they are available in different heights. I'm saying the blade is higher than the stock sight, so I've had to lower it all the way.  Here are top and side pics:

Yep, Weigand.

Generally used for PPC great idea just too high for bullseye.
Might need to get a higher front sight.
Also, FYI, it’s not legal for NRA DR matches. It is legal for NRA PPC dr competition

Didn't know it wasn't legal for DR, thanks.  I'd  to shoot DR, so if I do, I'll change it.

Does anyone know the stock sight blade height for a 6" 14/3?  I thought I kept it...I can't find it.  Midway has several different heights.  Midway has a .106" assembly and that looks way too small.  I can install just the blade.
Thanks, KUrt
