I know this is a heavily talked about topic. I've read for hours upon hours on this and various other forums, looking for a fix for my issues. I bought the Browning due to the false advertisement that it had mechanical triggers. Anyway... I have the 725 Sporting with 30" barrels in 12 gauge. I have recently purchased some 28 gauge companion tubes from Briley. I absolutely love shooting the 28 gauge for skeet but like the 12 gauge for sporting clays. But, what I don't love is the often failure to fire. I have talked to browning and they are well aware of the issues. They admit that the mechanically trigger still needs recoil to switch between barrels. The 2 Hammers are indeed mechanical but it takes inertia to switch the trigger mechanism between barrels. I asked if I could buy the trigger assembly for a 28 gauge and swap it for my 12 gauge. They said it will not fit as its a different size. I asked about the internals of the 28 gauge trigger and what was different and he said he wasn't really sure. He did recommend that I call Midwest gun works and talk with one of their gunsmiths. He said they aren't held to the same corporate liability standards and could give me more advice as to what needs to be done. I played phone tag with them yesterday and I'm still hoping to get a call back from the gunsmith at Midwest today. If I do I will for sure relay what I'm told. So, in all the reading I've done.....No one has came out and said what had to be done to get the trigger to work efficiently or this is what my gunsmith did, etc. I see where lots of guys have had issues and came on the forum and asked questions, then came back and said they had it fixed but didn't mention what that fix was or rather they never came back or commented. I've sent PM after PM to the original posters of these threads and got zero response. My 725 is currently at a gunsmith being evaluated. He is going to try and polish up some parts and stone some parts and see if that helps. He also agrees its odd that the trigger will work fine with snap caps but not with light loads. We were able to replicate my issues while I was at his shop. When my 725 fails to fire its like the trigger is dead. As if its not even cocked. He showed me where its getting hung up. The hammer, and it doesn't matter which barrel is fired first, was hanging up on the Sear. The hammer has 2 notches cut in it. Supposedly one is for a safety type feature and that is where the second barrel sear is hanging up on. When there is enough recoil this doesn't happen. You can often times keep pulling the trigger over and over and it will jiggle the gun enough to get it to release and then the gun will fire. If you have had this issue with a failure to fire and you have found a fix please let me know.
