PISTOL SIGHT INSTALLATION: Sight installation is an easy process with the correct tools and some mechanical knowledge. If you are not comfortable installing sights we recommend having a gunsmith do it. Listed above are 2 shops we recommend. Installing the rear sight and front sight (M&P) can be done with either a sight press or with a small hammer and aluminum or brass punch this is the recommended method. If using a hammer and punch we recommend placing the slide in a sturdy vise with padded jaws. Use the hammer and punch to remove the existing sight and then drift in the new sight.M&P pistols are designed to remove sight going from right to left and installed from left to right. Apply pressure only on the dovetail area of the sight. FP sights are designed to fit snug in the dovetail so that it doesn't move when shooting. In our experince it is not necessary to file the rear sight or front sight for installation, you may do so if you wish to make it easier to install. If you do so it will be at your own risk and should only be done very lightly. Once the sight is centered tighten the set screws. Blue loctite is recommended on these. When installing the front sight on Glock pistols, we recommend using red loctite on the front sight screw. All front and rear sights are designed to be installed with a snug fit in the dovetail with no fitting or filing required. Returns will not be authorized for sights that have been installed or filed. We cannot accept returns or exchanges for sights broken due to improper installation.
PROCTOR Y NOTCH SIGHTS ARE DESIGNED FOR POA=POI
SIGHT PICTURE SHOULD LOOK LIKE THIS IF YOU PRESS THE TRIGGER WITHOUT MOVING THE SIGHTS
IMPACT WILL BE BEHIND RED DOT
When I developed the Y notch and Square notch rear sights and sight sets, I wanted a set of pistol sights that offered speed and accuracy without a lot of room for sight misalignment error. I am extremely pleased with how they turned out and they have made my life easier when it comes to shooting pistols. While testing and developing the sights I noticed a few things. Before I get into my observations I should mention that to truly determine a zero or POA=POI we should be shooting very small groups consistently. With rifles 1 MOA is considered acceptable. That would be .25” groups at 25 yards. That is difficult to do with a pistol to say the least. I will accept 2” -3” groups with the pistol at 25 yards as a measurable of accuracy and POA=POI. I would encourage all shooters to push for something like that to quantify if your gun is set up right. You should also have a very defined point of aim and place the same sight alignment there for every shot. I would also recommend 5 shot groups with a pistol. Lots of times folks will aim at the middle of a paper target and shoot a 6” group to determine if their sights are good. That technique makes it difficult to quantify both point of aim and point of impact because ether isn’t a defined point of aim or a point of impact defined by a small enough group.
The things I discovered when testing my sights:
To determine if the sights where POA=POI I shot from a sandbag supported position to take human error out of the shot. To get a very refined point of aim and confirm the elevation was correct I placed perfect sight alignment on the bottom or top of a 3x5 index card at 25 yards. My front sight is .117 wide, at 25 yards it is as wide as the 3x5 index card! What that means to shooters is that even with a pretty thin front sight it is difficult to get a refined point of aim so that you are truly aiming at the same spot for every shot and shoot a small group. If you shoot a .125 or .135 front sight it is even more difficult.
My sights were designed to offer speed and accuracy with less room for sight misalignment error. For my style of shooting I want to see a front sight in a rear sight and that is good enough. I feel like the sights offer that easy and precise enough sight picture. To accomplish that I designed the sights with a narrower gap than most other sights for less windage error (the Y notch sights are opened up a bit more at the top to allow more speed with the precision) To help limit the amount of possible elevation error I went with a .180 tall front sight. Something I noticed when testing for POA=POI was that if I misaligned the elevation by one serration of the front sight it produced a 2” difference in POI at 25 yards! I should mention that the serrations on my sights are pretty thin, 50 lines per inch. What that tells us as shooters is that If we are zeroing we need to pay attention to all the details in sight alignment because little things can matter!
If you want to test your sights here’s how I do it:
Shoot from a seated position behind a table with a sand bag on it. Situate the gun on the sandbag where it is perfectly stable. For a target use a 3x5 index card at 25 yards. Place perfect sight alignment (the top of the front sight even with the top of the rear notch and an even amount of space between left and right of the front sight and rear notch). My Y Notch sights are designed for this type sight alignment only! Now place that sight alignment on the bottom of the index card. Dry fire. Watch the sights as you press the trigger, they shouldn’t move. Once you are comfortable, load up and shoot groups. I would shoot 5 round groups and wouldn’t accept anything larger than 3” if you can shoot 2-3, 3” groups and know that you have perfect sight alignment and placement you can quantify your sights are or are not POA=POI.
If you are still having problems, then you have the option to send me your gun though an FFL with return shipping. I will personally test it for POA/POI, if there is a problem we will do whatever we can to fix it.
