New HP9, front site goes into barrel-problem?

[safety first]

I can feel it sticks out a bit into the barrel,

would it nudge a slug, or otherwise affect the accuracy?

lastly,how common is this on other hp9's and should I file it down, or shoot it flat?

otherwise it's quite a piece of kit for 269.00 plus tax

Mine was like that too. Didn't seem to affect anything. Gun shot slugs straight as can be.
Still does in fact even after hundreds of rounds, so I don't know about shooting it flat.

I've never thought about this, but personally, I would take it out and file it down... I'd rather trim it too far and have the slight indent on the inside of the barrel, then have it sticking out. Just take it slow, trim off as much as you need, and make sure you don't destroy the threads.

 

[safety first]

Update, I left it because I decided that I could feel it, but maybe it was reemed with the barrel and it was flush enough.

and after the first 3(three) rounds of #8 2 3/4 Federal

the problem solved itself by the site blowing off the gun.

 

[diananike]

Holy crap.
I seem to remember some other people having this problem years ago.
Maybe you can just thread it for another bigger but still standard bead.
Mine never blew off, even after shooting 4-500 rounds of mixed full power slugs, buckshot and birdshot.
Now I have a XS big dot JB cold-welded over top of it so No worries.

well thats one way to fix a barrel obstruction.. shoot it till it fixes itself.

i was going to say get a dremel in there and make it flush, thats what i did to mine

 

[Can-down]

I think I hand(finger) sanded mine with emery cloth.....the brass is pretty soft.

 

[pope_face]

Not bad... at least it just blew the bead off, rather than getting caught on it and blowing out the barrel instead.

Why not put a fibre-optic sight on the front instead? If you've got a little patience, you could probably JB Weld the new sight over the hole, and then fill in the hole at the same time. Then just sand down the inside if any of the JBW sticks out into the barrel, and you're good to go.

Seeing as the bead was made of brass which is much softer than steel, the threads in the barrel are probably still okay.

The only problem may be that the Chinese may have used a non standard, posibly metric thread for their bead. Finding a replacement that fits may be an issue.

Whenever I have installed a new bead, I have used a dremel tool to very carefully (note my sigline!)remove the excess. Followed by hand (finger) sanding with emery to complete the final blending.

"non standard, possibly metric thread for their bead"

it's funny you mentioned this,

When I was buying this Hp9, I was like "right on a swivel mount on the stock", nice.

actually, not so nice, it's some small thread metric, much unlike any quality swivel stud I have ever seen ( Mike's) . No big deal, I just drilled my own hole and the swivel stud mounted securely. It must sound like a bad shotgun, actually it's really great, and has far exceeded my expectations. It's not too heavy and slings nicely on my back in the bush. Totally happy, I would have changed the sites anyway so I'm glad it blew off clean.

 

[diananike]

Mine shot way too high with the stock bead, I think that's why Remington put that pedestal on their short barreled guns.
I noticed my HP9 used the same thread size on the bead as a Winchester/Browning shotgun instead of the remington I was expecting.

 

[OC-3]

Mine was the same and I just filed it down.

 

[twoguntim]

Mine sticks out a bit as well, but not as bad. Never tried a slug, but has handled hundreds of birdshot shells. May think twice now that I see what can happen.

 

[Quack3298670]

Exactly the same problem I had. Shot 2 slugs through it and it's pretty much flush inside now. The bead is still there on top, just the portion that extended inside was shot away.

 

[brybenn]

The bigger the bullet the effected it is by little dings and marks.

 

[easy]

..., just the portion that extended inside was shot away.

How could that be? Lead is softer than brass. I think shooting just pushed the bead up. A pressed in bead will do that.

 

[sparq]

Mine is the same. the bead also seems to have been drilled at a bit of an angle (it leans forward towards the muzzle slightly). Doesn't seem to have affected anything. I've put probably 50 or so shells trough it, from bird to buck to slugs.

How could that be? Lead is softer than brass. I think shooting just pushed the bead up. A pressed in bead will do that.

Pressure is pressure - if the pressure exceeded the design shear strength of the stem of the bead, that portion was sheared off. Like water eroding a mountain - only with more velocity ;-)

Ever shot steel with a rifle? That soft lead will punch right through mild steel.

So I did a quick search, and saw it wasn't just me with this issue. Although without firing and just some cycling, its not scratchy burred or too sharp and everything else seems just fine with my expectations.

Looks like the best way is to remove, file down appropriately, and then replace with some loctite.

Here is my front bead sight sticking through on my new grizzly 8.5
