Westley Posted January 29, 2018 Report Share Posted January 29, 2018 Anyone have a 12 bore Beretta 391 magazine spring they would sell. All suppliers 'out of stock' at present and the gun keeps jamming on the last round. Link to comment Share on other sites More sharing options...
Saltings Posted January 30, 2018 Report Share Posted January 30, 2018 have a look in the magazine tube sometimes a load of crud gets in there use some brake pad cleaner to clear out and a very thin oil after failing that brownells uk should have a spring to help Link to comment Share on other sites More sharing options...

GarethR Posted January 30, 2018 Report Share Posted January 30, 2018 Check your piston too, only time that my gun jammed was when one of the edges had cracked on the piston. Also spray carb or choke cleaner down then grease it up, see how you go. If that fails let me know I may have one. Link to comment Share on other sites More sharing options...
Westley Posted February 1, 2018 Author Report Share Posted February 1, 2018 Thanks Guys, I had not thought about trying to get one from outside UK. I am fairly certain that it is the mag. spring because the entire gun is spotless, including the magazine tube, but it is always the last cartridge that is jamming. At the local clay ground last week, I could shoot the first target and then it would jam. I put 2 in the magazine which enabled me to shoot the pair, but the 3rd. round would then jam. I am guessing that the extra pressure on the spring of the 3rd. round in the magazine, allows the first 2 rounds to function normally, but then the weak spring is not allowing the final round to load correctly. The gun is a 2003 model and I do not think the spring has ever been exchanged. Link to comment Share on other sites More sharing options...

I have done this twice now, and it cures the fault instantly. Link to comment Share on other sites More sharing options...
sjnolloth Posted February 2, 2018 Report Share Posted February 2, 2018 Have a look at the piston holder on the barrel which is an integral part in making the second cartridge load correctly, there are small holes in it which get clogged up due to carbon. I use a small metal drill bit and twist by fingers gently to remove the carbon, i think from memory there is also a hole that goes into the barrel which also clogs, same again with the drill bit. I actually clean my piston in an ultrasonic cleaner that brings it up as new. Just an option. Link to comment Share on other sites More sharing options...
