Site adjustment, ok it's a beretta

[ERO1052]

I'm getting this group with the site lined up at the very top of the target. Consistent! Assume it's not me but the sites. How to I know what I need to to to the rear fixed site
25 yards range
Thanks

European combat hold, IMHO.

The acronym that's stuck in my head for adjusting sights is F.O.R.S.

Front Opposite Rear Same

You need to bring the P.O.I. up to the P.O.A, so you need to lower the front site or raise the rear. Measure the sight radius and do the math to tell you how much at your chosen zero range. I don't zoom right to the limit with a dremel or something, I only file off maybe 75% of the figure and go in bitty steps from there.

Well I don't want to grind the front site as it's part of the slide. So... I guess I need to measure the rear sight and 'do the math' and find a rear site that matches the new calculated height, higher than stock.

Right?

Thanks

What ammunition are you using? Slower bullets will tend to shoot lower.

Beretta does sell LPA adjustable sights for their guns, including one for the 92 that does not require replacement of the front sight. I, like you, had a lot of issues with POI vs POA with a brand new M9 I had, and this was an option I considered. Instead, I ended up trading the M9 for a S&W revolver, however I did recently handle another M9 fitted with the LPA sight, and it seems to be of decent quality, unlike the one I ordered and had installed on my Stoeger (Beretta) Cougar...

Edit: The sight was $57 available from Beretta USA the last I looked... If you are inclined to look at other options, I believe Kensight also makes one.

if you grind the front sight your hits will be higher on the paper not lower

The best way to remember how to adjust sights, is to not try and remember "rules."

Just imagine the sights being perfectly in alignment with the desired point of impact. Now, which way does the barrel need to go to move the point of impact? Now you can imagine the movement needed between sight and barrel. Make that happen!

This works whether you're adjusting the front or the rear sight. Much better to wrap your head around the issue than try to remember a "rule."

Did the rounds impact approximately where the dot in the center of the front sight covered the target? It is sighted that when the front sight is centered in and level with the rear sight - the impact should be where the dot is not the sight tip. Example C in this picture.

Also, Wilson Combat has taken a shine to Beretta and have fixed rears in different heights if you want to set it to your preferred sight picture / load.

Don't know why you put do the math in quotes. Is do the arithmetic more accurate?

Here's an example, using measurements in inches.

Change needed in sight height = (sight radius x correction)/range

For a 3 inch correction at 25 yards (900 inches) using the Beretta web site info of a 6.1" sight radius for a 92:

(6.1 x 3)/900 = 0.020"

Adjust recipe as needed.

That's what we're looking for here. He's aiming at the top of the target and hitting near the bull. (And a skosh left.)

If that's what works for you. I like to see what I'm shooting at, and where the bullets are going to hit, and prefer this sight picture:

Codenamedave, I used quotes as i was quoting someone else in this thread.

Anyway, you got the idea exactly. I'm aiming way high to get the group I show.

I did the math and have decided to get the WC 0.300 rear site installed.

Thanks all for the help.

Ps the schoch left on the group is due to bum right knee...

The problem with your "C" sight picture is at 25 yards the entire target is covered by my sights and muzzle. It's as if the red bullseye is actually the entire black target, make sense? I'm not sure that's the view I want, I'd rather have the top of my sight at the bottom of the bullseye, the 6 o'clock position, right now the top of my sight is at the very top of the target to get that group.

 

[BAM-BAM]

Beretta sights are combat not target sights:
"cover the desired point of impact with the front dot..... while lining up the three dots.... ooo........

The 6 O'clock hold you'd like to use is more of a Bullseye shooters hold to get a consistent POA

If off to the L or R you need a sight pusher.............

Shooting low is still an issue Go to Wilson for a new rear sight......

It's not my problem, it's how Beretta makes it. I was just informing you. I'm not endorsing it, I was just telling you what it is.

It's not "what works for me" I'm just saying how Beretta ships it. SigSauers are the same.

Beretta

That's not really a group to judge anything by.

I have seen this so many times with the Beretta's shooting left. It has always been the shooter and I was the same way when I got mine first.

Do the following:
-Have someone else who is versed in that Beretta shoot it
-Take more trigger finger out of the trigger, just gently press with your finger pad straight towards you, in a 180 straight line.
-Try to isolate pressure from your grip fingers from the trigger finger.
-Get the Wilson spring kit and trigger upgrade
-Practise practise practise
-Now mess with the rear sight.

 

[Zoner]

i completely missed the part about your POA being the top of the target....need to read haha. I'm not a Beretta shooter but if your front sight is " part of the slide"....not staked in or replacable your best bet would be changing out the rear sight

If he's holding at the top of the target, the POI needs to be lowered. Thereby lowering the rear sight or raising the front sight.
Edit: Nah, I got it "backerds". Carry on.

Well that's a different story than your earlier post. Even if that's what Beretta intended, it's possible that people with different eyesight, grip strength, etc. may not produce that effect. Then there's those of us that prefer a different sight picture.

Anyway it sounds like ERO1052 got it figgered.
