How much rib do you see on a Beretta 391


B391

Recommended Posts

I have a sporting 391 Urika and I am struggling with the sight picture. It seems to shoot low when I see along the rib. I think i have to see over the rib by about the height of 2 £ coins stacked which seems high to me.

 

Anyone else have the same issue/

I have one and was seeing a little too much rib until I changed the butt pad from the stock 28mm jobbie to a 13mm one. Initially, I found that with a similar amount of rib showing to you, I was shooting too high which I'd expect. Now I don't get distracted as the gun fits better and bringing it to the point aligns the bead with the back of the barrel with very little rib showing. Shooting too low to me might imply not enough LOP? Have you tried moving your front grip a little further back on the forestock? Little things seem to matter when trying for consistency but agree with the above comments...try using one of the shims or alter the pad to try and customise fit. Don't know about you but seeing too much rib I find distracting (unless relating to the female of the species :lol: )

hello, the only sure way is to use a try gun with full adjustable stock and put the measurement to get your stock same. then on a pattern plate, or try the pattern plate first to check the gun is not shooting high in the first place, most guns come with a standard LOP but as we know may need a slight adjustment for you it sounds like an extra shim might lift the barrel to eliminate seeing as you describe.anyway hope you get sorted.

This is one of the reasons I don't get on with Berettas; I like to see very little rib and with Berettas I see far too much. You can have the comb shaved or the stock adjusted, the latter being quite easy as far as I'm aware, with an auto.

 

 

I don't think it's exclusive to Beretta to be fair Scully but depends entirely on the individual and the gun design (ie drop, LOP etc). My 686 in "standard" LOP fits well and has very little rib showing...it's almost perfect for me out of the box. My A391 wasn't and took some adjustment to get it close, but even then, the drop doesn't seem quite as much as the 686 uses. I've always been of the opinion that as long as you know where the gun throws the centre of the pattern at say 30 yds, you can get used to most guns, but the ones you'll shoot best with are the ones that come up most naturally to the point with least distraction from rib or poor LOP fit or cast issues. That tends not IME to translate to any one particular brand and is more about the particular gun.

You could well be right, but every Beretta OU I've ever tried belts my cheekbone as I have to squash my cheek down onto the comb to get the sight picture I prefer.

Beartooth Comb Raiser?

 

I seem fine with most Beretta semi autos, but struggled with a 686 (all 14 1/2" LOP)

 

They sell various thicknesses of butt pad though so easy enough to shave off or add a little as needed. One reason I like Beretta is the service. I ordered a new butt pad for the 391 two days ago, and it arrived, complete with a nice large freebee calendar today shipped from Italy! Few suppliers in the UK manage that sort of service.

Why would he want a comb raiser if he's seeing to much rib already?? All that will do is raise the cheek even higher, your cheek does not need to be Compressed to shoot well, we are all individuals, I like a really low comb and like to look down the rib

thanks for the replies. My Miroku MK60 fit well and i naturally see the figure of 8 and i tend to hit what i see.

 

Made me wonder if the 391 shoots low, i shot a few rabbit clays at about 30yrds and it seems to hit the ground short of the clay hence shooting low when looking along the rib. If i can see quite a lot of rib then i was hitting them

 

is that LOP being too short? should i try a but pad as a tempm solution to lengthen LOP by 1/2 inch or so or do you think it is something else?

 

I did increase the drop from the standard 60mm to a 65mm shim but it seemed to make it worse. now back to 60. I could try 55mm but now not sure what to do

My one for very flat with a teuage choke but a tad low with the standard beretta optima plus choke

 

Interesting. To compensate do you lower the comb on your cheek to see more rib to shoot higher in compensation or do you cover the target more? With the MK 60 the bead for me is at the lower edge of a level trajectory going away but I have to cover the bird with the barrel using the 391.

 

Ideally I would like to get the same sight picture with both of them
