67-1 shoots VERY high
Hello all, I recently acquired a 67-1 (later non pinned), that shoots extremely high. Now before anyone asks, the rear sight is bottomed out all the way down.
With 158 grain it was about 6” high at 15 yards. This load shoots point of aim with with my fixed sight revolvers and middle of adjustment with my adjustable ones. Both S&w and Ruger.
With a 125 grain load that will shoot low in those same guns (without sight adjustment), I was about 1” high with the 67!
It doesn’t really bother me as I load more 125 grain and will just stick to those in this gun but it struck me as weird that it shoots soooooo high.
Anyone else ever hear of this? Maybe my rear sight was changed out sometime? I did a quick measurement and the top of the blade to the top of the base where the blade sits is .150” or roughly that.

What it sounds like to me is that your front sight is too low for your rear sight.
If you think the sights might have been changed at one time, you´re probably right.
A shorter front sight will raise your point of aim.

Just on the off chance, could the
stocks be affecting your aim? The
standard stocks on the 67s were
the magnas.
Perhaps a different set of stocks will
change things. Or not.

Some judicious filing off the top of your year sight will help some. If you don't want to do that, you could replace the rear sight with a minimum height one. 6" at 15 yards is really a lot to correct.
If you want to lower the top of your rear sight, you'll need to bring it down about .066" to fix 6" at 15 yards. .066" is actually quite a bit on the rear sight so perhaps a higher front sight if that is possible on your particular Model 67.
I once brought down a Model 14's rear sight in that manner with good results although the depth of the notch is somewhat shallow now. It's not noticeable when shooting.

The way to measure the rear sight is to run it out of the body and measure the blade height with a caliper or micrometer. Normal sight blade size for a 67 should be much shorter than .150, more like .126. If I am visualizing your measuring method, your rear sight blade is really more than .150, probably a .160, which is way too tall for a model 15 or 67.
Lower the rear sight lowers the impact on the target, so you need a shorter blade.

You are correct and I had a few minutes today to measure properly and it was .160” give or take. Guess I need a new one and that explains it.
The magnas have been replaced with hogue (ugly, I know), as they fit my hands well and I have them on all of my revolvers for shooting.
Front sight looks original and like most smiths not easily changeable.

After some quick googling it looks like the 15/67 with 4” barrel use an ultra low .106” blade. Guess that explains why mine with the tallest blade hits so high.
Thanks everyone!

I really do not like the low rear sights, one of the reasons I don't have a 67 or 15! As you probably know, filing down the front sight as suggested in one of the posts will make the gun shoot higher!
Those sight blade changes can be a source of frustration, even if you have done them before! Parts are available from the factory, most likely. If not there are other sources. I had a model 63 that had a very short blade and found a taller blade at a secondary source. Factory did not have the part!!

I would just keep doing what you said, shooting it with your 125gr handloads. Let the next owner change things if they want.

Before making an in-depth analysis of the handgun's sight system, I would have to see you shoot. Handguns recoil upward significantly for everyone. Some learn to be consistent in how much that is with every shot. Various loads in the ammo used will also affect that amount of recoil. Our reaction to each handgun shot can vary to the anticipation
of the shot, sound of the shot, speed of recoil impact and just the general 'feel' of the shot. I think there is a good chance your stance, hand grip, trigger press and anticipation are all at work in this case.
Suggestion: make a simple handgun rest for bench testing your loads and variation in POI between loads. Note, your POI will vary slightly from benchrest to standing offhand shot.

All good things to look at. However to address all of the above I used a bench to verify this once it was hitting off of the target so bad.
I do understand what you’re saying too and I have several other k 38’s and they’re all right on target with my 158lswc over 3.7 hp-38 load and they all shoot low with my 125 truncated nose lead bullets over 4.0 hp-38 loads. This gun was shooting exactly the same distances between the 2 loads but much higher. I use these 2 loads along with a real soft shooting load with trail boss almost exclusively anymore.
I spoke with Dean over at Brownells and he confirmed that the sight for a 4” 67/15 is indeed .106”.
On a side note I was thinking about you the other day and wondering if that old 27 is still treating you good!

LOL; when I saw your post the first thought that came to mind was just how much I enjoy that M 27. For a long time I had to wish for another just a good, but now I'm at the point of decreasing the herd not increasing it. .... :-(

Sorry to hear that you’re decreasing your guns. That 27 is one of the ones I have regretted moving. You’ll laugh but the other 2 I regret the most are my model 10-5 (nothing special but it shot better than any gun I own and was my first older S&w), and my model 49.
