Beretta 3901 New to me

Recommended Posts

I just bought a beretta 3901 off gun broker. Does anyone have one of these or familiar with them? I got it to use for sporting clays. Anyone know which choke system it uses, i found it says mobilchoke's. But it seems there are several different mobilechokes. Any advice or info on this shotgun would be nice too.

There is Mobil-Choke and Optima-Choke. Mobil-Choke uses standard barrel internal dimensions respective for its gauge. Optima-Choke tubes are a bit longer in length and are designed for over-bored barrels. There are also different styles of Optima-Choke tubes. Both M & O can be had in flush fitting or extended length tubes. 3901's I'm certain were Mobil-Choke only.

thank you for that info. Yea i think its mobilchoke only. I have never used a choke tube shotgun. I have an 1100 which doesnt have chokes. Do i get the flush mount, extended, ported ect? Also i plan on shooting cheap federal 12ga 2 3/4 #7.5 or 8. I think that ammo is lead based but not sure. Do i need one that is steel shot compatible? Or anything specific. Also do i need any special tool to screw the choke in?

Mobil-Chokes are all steel compatible. Beretta sells a choke tube wrench that works well. Years ago they sold a choke tube removal tool that also had a thread chaser on the other end so you could clean the threads in the barrel. I don't see style that sold anymore. You might find one used on eBay.

 

You should be fine with flush-mounted tubes. Skeet, IC or MOD would be a good start for a skeet/clays course. MOD or IMOD or FULL for trap. After-market makers also make Mobil-Choke compatible tubes. 

 

Best choke removal tool I've used from Precision Reloading:

    • The  12-1 compression ratio L88 is long gone. This is GM's updated version. it might be  pump gas 10-1 engine The L88 was a aluminum head  cast iron block engine with a nasty solid lifter cam. the  ZL1 was a all aluminum  12 or 13-1 compression ratio engine with the best forged internal parts at the time and had a even nastier solid lifter cam 
    • I like my regular carry holster.  OWB leather with belt slots.  I've been carrying for over a year and it was comfortable and I hardly even noticed it.  I carry (usually) a Ruger LCP .380 - light, convenient, tiny. But...today I ended up taking it off an leaving it home after a few hours. I cut down a big maple tree a few days ago and I spent 3/4 of today loading and unloading firewood into the back of my truck and a trailer.  It was a warm day, I was dirty, tired, sweaty, and my holster was rubbing against my side.  The leather and exposed metal snap was no longer comfortable. I'm thinking about adding a layer of something to that part of the holster to soften the contact.  Anything insulating will make it worse.  I don't want a sweaty, hotter holster against my skin.  I'm imagining something thin, breathable, that won't absorb sweat, and softer than leather, metal snaps, and rivets.   But I have no idea what would work. I'm hoping somebody else has already figured this out and I can just do what they did. Any suggestions appreciated.
    • Check the primers on the ammo you didn't shoot yet. Are they fully seated? If the primer is not just below flush with the back of the case, the first hit can seat it better then the second hit ignites it.
