SD9 ACCURACY???
 
wats up team? i want to hear from the SD owners/shooters about the accuracy of the pistol. the wife told me she was getting me a gun for my up coming birthday!:D and i think the SD9 is my next addition. i have the sigma 40 and learned to shoot it with pretty good accuracy. but most of us know that it shoots low and adjustments have to be made to get it 'zeored_in'. i know the hiviz upgrade has been successful for the ones that have already tried it. i plan to do it once i get the chance. but i'd like to know if the SD9 is on point or if adjustments are needed like the sigma. also, info on groupings, ammo used, and distance would be awesome as well. thx team!

Mine was dead on right out of the box.

My sight was 2 feet off at 20 yards out of the box. Few quick adjustments and all was good. I remember the first shot, I was literally like "*** where did it hit?" then saw the puff of dust at the 100 yard bunker...

Mine soot POI. No problems with mine.

zeroed_in 02-09-2011 11:20 AM

thx for the feedback! hopefully things go well and i'll have an SD9 in a couple weeks:D

With the 9mm I noticed it shoots about 4" low at 15 yards when using 115gr, using 124gr it shoots dead on. I now reload my 9mm 115gr and have adjusted my load to shoot point of aim at 15 yards and have great results. I was shooting whatever cheap ammo I could get my hands on before reloading and now load and shoot far more often.

Accuracy and velocity are relative

mine shoots 2" low at 10 yrds. groups nice, just low.

Hosa32726 02-26-2011 09:00 PM

mine shoots 2" to the left and it is also low with 115 grain ammo. forget using a laser sight since the frame is not centered with the slide. Major defect that S&W refuses to admit. It is even on their website when you view the 360 degree image of the SD 9.

wow! wouldn't that cause the barrel to be off centered as well? could that be the reason for the slight inaccuracy?

Only if your sights are on the frame....

There are some serious misunderstandings about laser sights going around.
First, none of the lasers can be mounted coaxially with the barrel (looking down the barrel), so there is always parallax error between the laser path and the bullet trajectory. It makes no difference whether the laser is mounted below, to the side, or a little of both: there is only one point where the two paths intersect.

When adjusting the laser, there are two common choices:
1. Pick a distance and sight the laser to POI at that distance. There will be an error at all other distances, and the error will increase with range.
2. Adjust the laser so its path is essentially parallel to the bullet trajectory at short to medium range. There will be an error at all practical ranges about equal to the distance between the bore axis and the laser. Although this sounds worse, many find it easier and more predictable in use.

The preferred place optically for mounting the laser is on top of the slide, but that would take away the iron sights, which are needed when the laser quits.

I see a lot of people using method 2, Knowing you will hit 1" high at any distance is a lot easier than trying to set it at say 15 yards and then remember where you will be high or low.

Also whether the slide is "off" or not is irrelevant because you adjust the laser to POI. It has nothing to do with the slide or barrel. It is set to where it impacts.

If I were to use a laser in would not be a rail type, but a guide rod type from LaserMax Hi-Brite Internal Guide Rod Laserm. But they only make these for the S&W M&P fullsize and a few other handgun companies. But if you got to have your extra toys, find one that adjust both vertical and horizontal, just never needed one myself.

S&W Rover 03-02-2011 11:03 PM

Speaking of accuracy... just installed a Warren plain tactical sight on my SD9. It is a one to one replacement for the S&W sight.

The Warren tactical sight is all black (no white dots) and has a U shaped opening that is a little bigger than standard and the sides have a curved design -- all of which (theoretically) combines to make your eye move to the front sight very naturally and quickly. This should work well with the SD front sight, which is a bright tritium/white-ringed dot.

So far, dry-firing, I like it. We'll see how it works on the range.

Your Right!! I just found this forum. I just bought the SD9. Mine is like that too and a youtube reviewer complained about that also. I did a google search for this issue and found the forum. This is my first post. I also have a new Model 442-2 revolver. I do like the feel of this SD9 over my Glock19 though

Matt7275 03-06-2012 12:00 AM

Love my SD40. By far favorite handgun I own. no mods. POI

cshoff 03-06-2012 01:26 PM

Both of my .40 caliber Sigma's shot to POA right out of the box. I'm not sure where the idea that they "shoot low and adjustments have to be made to get it 'zeroed_in'" comes from. As to the SD, I don't own one so I can't provide an opinion on those.

thndrchiken 03-06-2012 01:37 PM

Most likely because they are sighting with a 6 o'clock hold, not a combat hold which is what the sights are set for.

Fat B 03-06-2012 03:09 PM

My SD was POA right of of the box. With that being said, the trigger on the SD took alot of getting used to. Defenitely not the 1911 I was used to shooting. I don't know if it was the hinged trigger, the longer pull, or 8 1/2 pound pull. Probably a combination of the three. If I find myself slacking on mechanics I group the shots low and to the left even with a slow and steady trigger pull. Not too bad, just not dead on. I've seen the chart that supposed to help you out in fixing whatever is wrong but I've never found it to be very much help. When i concentrate, it's dead on.

The accuracy thing cracks me up sometimes with people claiming gun X shoots low and left or high and right. I promise if if bolt that gun to a bench it will be very accurate as long as the barrel is straight. Most claims of a gun not being accurate are due to poor trigger control/poor grip or not a clear understanding of how the sights are set up.

Ditto! mine does too !

Chuck1217 03-08-2012 05:14 PM

Mine too, it's better'n me.

darksideemt 03-08-2012 05:23 PM

I got a SD40 for my wife and M&P40 for myself. I shot mine first from about 25yrd and had good grouping just a little down to the left. Then I shot the SD and was way off to the right, from same distance and same hold. In another thread I posted it was stated it was probably due to the trigger pull being so different the M&P and the distance I was shooting from. Now that I have found this wonderful place, I plan on using what I have learned this weekend and go shoot again. I will be posting pics and report after, now that I have been schooled a little. Still love the gun and glad I bought it, I just need to learn how to shoot.

Jinseru 03-15-2012 03:54 AM

Out of the box...

At 5 yards I can hit the same holes almost over and over again.

At 7 yards I can hit the same spot most of the time.

At 10 yards I hit dead center with a tight grouping <1in

At 15 yards still hitting dead center with tight grouping 1 - 3in.

At 20 yards hitting a little low (<1in) with tight grouping 1 - 5in.

At 25 yards hitting lower (2 - 3in) with decent grouping

I blame some of the low shots on me anticipating recoil. Although I've almost fully fixed my own error, it shows more at longer distances.

I'm using 9mm 115gr federal classic rounds.
