637 Shoots high

[David R]

30 feet, DA 6:00 hold in my back yard all handloads.

Today I suck at photos. These are from my phone.

The question is do I deal with it or send it back.

I traded a BG38 for this, its 3x the gun. Still tight and like new. Weighs only 3/4 ounce more.
I was thinking crimson trace laser grips, but I love the grip that came with it. It fits my big hands and
conceals better than the BG 38.

You may not accept the suggestion but IMO it's quite possible you are "pulling" the gun high. These revolvers are somewhat notable for a heavy DA trigger and with the relatively tiny grips normally installed on them it's sort of expected to experience some movement of the gun during the trigger stroke. If this is what is happening simple practice will resolve the issue in time. Note, a bit of good news is that even while shooting high you are still getting acceptable accuracy in Defense terms at this distance, so your doing a lot better than I would with one of these pocket rockets.

Now, one suggestion that will probably allow you to get a much better idea if you have a sighting issue. That is to shoot it carefully in single action from a rest. Yeah, I know that won't prove anything in terms of Defense accuracy but it will confirm if you have a sighting issue.

I have to ask the question where are you holding your front sight?

And looking at your group with the 110gr rounds, you may be anticipating the recoil. 930 fps with a 150 gr round is a fair amount of recoil in a j frame. Not uncontrollable in the least.

You may be holding up a touch too much front sight also.

Just thoughts on my part

The 6 o'clock position may be at issue here...? Both my 686 & 617 came from the factory "sighted" in with the front sight on top (covering) of POI. They both required some windage adjustment only.

 

[GreyRider]

Hmmm.... But that would have you shooting low, wouldn't it?

Peoples eyes can be different. And there's not much of a rear notch on those little J frames. But, with my J frames I have to bury the front sight in the rear notch quite a bit to get it to hit where I want it to.

Also I've always used 158 gr ammo. Don't know if that will make a difference or not at 30 feet.
( edit, oophs , I just went back and saw you were using 150 swc and were shooting higher ,, never mind ,, )

Look on the bright side,, at about 75 yds. you should be dead on.

Your groups look pretty good.

Hi David, great to talk to another NRA Life Member! Actually, I think you're just fine! First, that is an AWFULLY tiny bulls eye for 10 yards. You may want to try a regular pistol target and fire the gun from a rest position. A more comfy grip might help with group size, if your goal is determining mechanical accuracy and POI.

I do most of my 'work' with the J-snubs. Have no idea what they do on a bulls eye, they are all MOPP (minute-of-pie-plate) guns. If I can keep them on a pie plate or 1/2 sheet of typing paper at 3-7 yards double tap, I'm content. But that's just me.

Some people are gonna hate me for this, but have you tried standard factory ammunition, if only as a frame of reference? See what factory ball or LRN service loads do in the gun.

Above all, follow the tips given by the previous posters as to grip and sight picture. They know a lot more about accuracy shooting than I. And keep that gun, none better!

When i read the OP's post this morning, I obviously wasn't paying enough attention to the size of the targets...
(Not enough coffee)

That 637 is not a target pistol and those are a respectable showing at 10 yds. I will agree with kaascop on this. Your fine.

Your chances of having to use a j frame at 30 feet? Unlikely.
10 feet or less..Oh Yes. Under 10 feet..essentially you are fighting for your life. Accuracy with a a j frame or other small weapon I describe as "Minute of Bad Guy".

I wont get into the why's and therefore's of self defense with a handgun. With practice and you should practice regularly if using a j frame, double action and become comfortable with it.

Again, just my thoughts on the subject.

oldafsp: Thanks for the back. You know what you're talking about! BTW, I also use pie plates for pie...

Hope we have the OP squared away. Hate to see someone tearing himself up when unnecessary. Appreciate. Stay safe, partner.

Thanks for the advice. I will keep it as is. I didn't know if S&W could or would make an adjustment that small. It shoots the same POI single action. I shoot double action until the targets get far away. I have tried a few +P 158. They shoot a little higher with less control. The first one is pretty good, but it goes down hill from there. Its a hard gun to shoot with really hot loads. I have no idea how a 357 would be. I would not even want to try in a light gun.

This gun has been in an ankle holster or occasionally IWB since I bought it. Compared to my LCP, which sits in the safe, its my "Big Gun" .

I find the 110 XTP have less felt recoil than the heavier hot loads. More muzzle flash and a louder bang, but easier on the hands and trigger finger.

The 150 or 158 shoot about 3" high, the 110 shoot about 2" high. If I put the front blade halfway up (down?) the rear notch its about on. I can't add to the front sight....... Can I?

Here is one more target.

More practice!

Your asking to change the gun to meet POA! Wrong question! With a fixed sighted gun you change the load to meet POA! Your last post with the targets has the key to your problem! From a pistol shot off hand the lighter weight bullets will hit lower at the same distance. This is due to the recoil of the heavy bullets which make the barrel rise more before the bullet exits the barrel. Also the speed of the bullet has the same effect, slow bullets are in the barrel longer in the recoil arch! This action of bullet rise in relation to POA is really apparent at longer distances(100yds+) when shooting pistols.
