In a previous blog comparing Ruger’s .357 Bisley, the Ruger Blackhawk, and the Colt Python with the Missouri 180-grain bullet and IMR 4227 propellant, I mentioned that the Colt Python rear sight is a real rinky dink design. Specifically, the set screw that holds the windage adjustment in place is not up to the job. Mine wouldn’t secure the windage blade, and when I tried to tighten it, the set screw’s Allen socket surrendered. Surrender would be good for the IRGC; on a high-priced revolver component, not so much.

Faced with this situation, I did what Wilson Combat wanted me to do: I ordered their upgraded, more robust rear sight. At $119, it’s not cheap. It probably cost less than $3 to manufacture. The high price was undoubtedly due to the nonrecurring engineering that went into it, but based on my results on the range, I don’t think Wilson got what they paid for from their engineering department. I sure didn’t (more on that in a second). I bought the Wilson Combat rear sight on Amazon Prime, so I saved a few bucks on shipping and that was good. I received the part the next morning, and that was good, too.


The Wilson upgrade comes in a nice plastic display package, and it includes everything needed: A complete rear sight assembly, a spring, the elevation adjustment screw, and installation instructions (although the thing is so basic the instructions aren’t really needed).




I installed my Wilson Combat replacement sight the day I received it, using simple gunsmithing tools I had previously purchased: A set of brass punches, a universal bench block, and a small brass hammer. The brass tools are necessary because the Python is made of stainless steel, and I didn’t want to mar any of the revolver’s polished surfaces.

The first step was to tap out the stock rear sight’s roll pin. Colt uses a roll pin instead of a simple pin, and that’s a good thing. Roll pins stay put. Other manufacturers use simple pins, and my experience has been that they constantly back out under recoil.
Once I had removed the Python’s stock rear sight, I compared it to the Wilson Combat replacement.




I like the Wilson Combat’s clean look, it’s slightly longer sighting radius (i.e., distance from the front sight), and the serrated rear sight blade. The theory behind a serrated rear sight blade is that it cuts down on reflections (although I think that’s more a marketing shtick than a real advantage). I like the look better, though. The width of the rear sight slot appeared to be about the same as the stock Python rear sight. The notch’s depth was greater, so that’s good. What wasn’t good, though, was that the Wilson Combat rear sight appeared to be taller than the stock part. That would make the gun shoot high. I hoped I was wrong about that, and that once I had new sight installed, it would not be any taller. As I had that thought, I was reminded of the old saying: Poop in one hand, hope in the other, and see which one fills up first.
The Wilson Combat rear sight spring is way stronger than the stock spring, and I had a hard time attempting to get everything aligned so that I could tap in the roll pin. I gave up and used the stock spring (the one that was originally under the stock rear sight).
When I had the gun reassembled, I examined it. The rear sight was indeed taller than the original equipment Colt sight, even with the elevation adjustment lowered as far as it would go.


I went to the range the next day, and shooting my 180-grain Missouri bullet load (with 14.0 grains of IMR 4227), I found that the Wilson sight absolutely did shoot high. As can be seen from the photo at the top of this blog, the Python now shoots about 2.880 inches high with the rear sight in its lowest position. Hmmm. I looked at both my hands. Neither contained any hope.
I tried another load I like (a 158-grain jacketed hollowpoint with 15.0 grains of IMR 4227). It, too, was high at 45 feet. I expected it to be slightly higher than the 180-grain bullet load. It was about the same, which is to say it, too, shot too high.
The Wilson rear sight has no wobble; the stock Colt rear sight can be wiggled around quite a bit. Because of that, I think the Wilson sight will group better, although I have no data that proves this. Unlike the stock Colt rear sight, the Wilson rear sight has positive clicks for windage adjustment. That is a definite improvement. There’s no more Mickey Mousing around with a microscopic set screw. I think the Wilson rear sight presents a cleaner sight picture than the stock Colt rear sight. That’s subjective on my part, but it was definitely there for me.
Overall, I was disappointed with the Wilson Combat rear sight. For a part that costs $120, I expected more. It’s not beyond the state of the art to engineer a rear sight that will work with the stock front sight. It’s ludicrous to offer a “replacement” rear sight that makes the revolver shoot high.
On this business of shooting too high, and just for grins, I took a few shots at a rock about 130 yards out. With the Wilson sight, the Python and I were hitting it consistently. But that’s with the sight adjusted as low as it will go. I guess the good news is that I can now adjust the Python to hit targets in the next county (sarcasm alert here, folks).
Given the current design, the answer is a taller front sight, and that will become the topic of a future blog. Not surprisingly, there are outfits out there selling those, too. Maybe that was the plan all along, and on this issue of a better set of Colt Python sights, I’m not done yet.
Stay tuned, my friends.
A Few Thoughts On “Windage”
The left-t0-right (or right-to-left) windage adjustment on a firearm’s rear sight is seldom used to compensate for wind. It’s used to account for a firearm’s printing to the left or the right of the shooter’s aim point. A shooter moves the rear sight’s windage adjustment to the right or to the left to bring the center of the group in line with the aim point (the spot where the shooter aligns the front and rear sights on the target). Usually, once this “windage” adjustment is made for a particular load or brand of ammunition, it is left there. We don’t move the windage adjustment to compensate for the wind blowing; if the wind is blowing, we simply hold to the left or the right of the target to compensate for the wind moving the bullet.
You might think that if there’s no wind blowing, a gun’s rear sight could be placed exactly along the centerline of the firearm to hit the target. That’s seldom the case, though. The bullets’ impact on the target will be biased to the left or the right due to factors built into the gun and the way the gun recoils in the shooter’s hand (which varies from shooter to shooter). We compensate for this left or right bias by adjusting the rear sight’s “windage.”

Iceland has been on my bucket list for a couple decades and for one reason or another it just never came to fruition. I decided to go against all common sense and make it happen (yes, in late November). Packing nothing but a small backpack, I was off the following day on a nonstop flight to Reykjavik.
