but you are going to look and feel out of place. Plus you won't hit anything with 18.5 inch barrel. I would suggest just renting and O/U at the range, or maybe a Beretta A391 semi auto. Likely the range will have them to rent. You'll have more fun, since you might hit something.

Well, We're a Beretta family, so if I get another O/U, I'm sort of obligated. My brother-in-law was a rep. I do have a Rizzini O/U skeet, it's an older one from the 80's. Actually, my first shotgun.

I looked at the schematic and the video. Looks like a blow back system to me with a rotating block. Doesn't matter, as long as it works. The recoil system is interesting, seems to rely on the absorption of the impact through the stock, which is designed to flex with the energy. My Xtrema has a spring plunger in the butt stock that absorbs the recoil like a car's shock absorber. It works very well, but you can feel it spring back into place sometimes. Those that are sensitive and want everything perfect with their guns might not like it. Doesn't bother me any, I can go through 8, even 10 or 11 boxes of shells in an afternoon practicing sporting clays and my shoulder is fine. Anyway, Vinci looks like a fine gun. If I didn't already have the Xtrema, I would consider it. I'm looking for another O/U for my next purchase.

It's a blow-back system? I wonder how they did that?! Interesting. Somehow, you have to allow exit of the gas of the heavier loads, trap it for the lighter loads. I guess with good engineering, anything is possible. Well, I like the Xtrema. I'm sure the Vinci is a fine gun.

Since Benelli and Beretta are the same company, I'm wondering what's the difference between the Vinci and the Xtrema2, other than looks? Just wondering. I have a Benelli M4, and I have a Beretta Xtrema2.

YEP, that's the first thing I thought when I read the above post. Better off dead, than in the courtroom. End up causing permanent injury, you might have your wages garnished until you have no more wages. I have experience shooting sporting clays, no experience shooting intruders. If the MOD choke allows you to shoot slugs, then it can handle anything, and there's no reason to change it. My brother-in-law, until very recently, was one of the major Benelli reps, which is how I got my M4 (at cost mind you). I asked him about the stock Modified choke, and he said that it's there for a reason, it can handle anything.

Holy crap, I found people with good taste in movies. Starship Troopers, greatest movie ever. Along with H&K, and Team America. Ahh....guns and movies. My favorite.

And killed NPH, greatest actor ever. Blasphemy.

The website states they are backordered. As my Tacstar extension only increases a disappointing +1, I would like one of these tubes. I always like a project. I don't think I will having a problem installing.

Well, The site won't let me upload pics for some reason. It says I have already uploaded the maximum of 1 files. I didn't load any files. I'm working on a Mac with Firefox, maybe there is some capability. I will try tomorrow from work PC. Anyway, I tried three different brands of shells, Winchester, Federal, and Remington. All only load 6 in the tube with the mag extension. And, it's not even close. I said before there was 1/8 left, but actually it looks like that veries from 1/4 to maybe 1/2 inch. There is a ridge in the mag extension that holds back the follower, and it seems the ridge is placed to close to the receiver to allow an extra two shells. Others seem to have the same problem. Funny thing is, the packaging clearly states "Benelli M4 7-shot". I learned a new thing, how to float a shell in the carrier, from these forums. Yes, if you float a shell, it's 7. Maybe that is what they meant. Another piece of good advice was to use the OEM spring. I noticed cycling the shells through, that with the TacStar spring (which is considerably shorter), the last round out of the tube would not completely load into the carrier every so often. So, I put in the OEM spring. No problems. Last round shoots out right into the carrier. Floating the shell seems to cycle fine- by hand anyway, still have not tried firing this. So, it looks like if I want 7 rounds, I have to either buy that factory extension tube off Gunbroker for $180, or get a full length tube. I do have a heat gun. I will try this one I have and see how it functions with live fire. I got it for free afterall. Thanks for the help.

Full length tube you mean? Cleefurd, Your math is reasonable, but there is one thing you are probably not aware of that is not math related. I alluded to it in the earlier posts. There is a ridge on the inside of this tube that stops the follower. If that ridge has been placed more proximal than it should be, you will never get the last round in. That is a manufacturing issue that is out of our control. I can see the ridge. I unscrewed the end cap and took the spring out. I put the shells in, and I saw the follower stopped at the ridge. Spring doesn't matter. Anyway, I will still try some different shells tonight and see what happens. I have a couple of different boxes of stuff. I also noticed that the very last shell out of the tube does not always fully eject into the carrier. That is probably a spring issue. I might need to replace the spring. I might need to buy that factory extension. I also need a good tri or quad rail system. I can get a free handle from my brother-in-law. I just need a good foreend stock replacement with rails. Anyone recommend one? Surefire? Check this one out: http://www.zahal.org/FAB/M4penelli.html

I figured as much, because as far as I could tell, it has nothing to do with the spring, but more with the construction of the extension tube. I also know I'm not retarded and I did put it on correctly. Weird, because the packaging claims +2. Well, as long as it works. I have not fired it yet.

when I get home tonight, I will try a different brand of shells. I think I have a box of Remingston somewhere, and I know I have Federal 00 buck in my Mossberg. I will post a picture. Another thread someone posted the same problem, but no resolution to the problem. I have a feeling it is the way the extension tube was made. Other than this issue, it seems to fit pretty solid. Finish doesn't match the mag tube, but is the same as the original limiter cap (black). I think the OEM spring will be too short to reliably feed the last couple of rounds into the carrier, but I will try it.

Hello, In terms of the spring, I put in the one that came with the tacstar. Doesn't matter, because I tried loading shells with the end cap off and the spring out (I won't do that again, it's hard to get them out with no spring!!). The follower (whatever you call the piece that pushes the shells out of the tube) hits the end of the mag extension too early, so limits the number of shells you can put it. Type of shells I tried, were Winchester game loads, 2 3/4 inches. I don't think there is a limiter plug, but I don't know. My gun is just basically stock out of the box. Does it come stock with a limiter plug?? I shined a light in there, but I'm not sure what to look for. I saw limiter plug installation instructions in the manual, but I don't have anything that looks like that in the gun.

Me too, I had the same question. It only added plus one. I posted a separate thread on this. I got my Tacstar extension for free. If it doesn't work out, I guess I'll look for a full length tube.
