Hate to hijack but I tried searching. Can someone explain the FN sealed piston. And who makes it.
My fN has never failed but I'm at the 500 round mark.
The hammer on my daughter's Edge started following the slide also and we found a tip of her sear spring had broken off .Not exactly sure if that is what yours was doing
I use range brass also and I visually check powder in every round while loading. I've only had one 9mm round rupture no harm to the gun just added a few seconds to my daughters time. I've got enough cases they are only getting used once a year
I think the OP is probably against forum rules but it does makes me feel better about paying 300 dollars for 8,10 and 12 inch plates the other day. I did get a bit more then just the plain plate with mine .
If someone makes a left handed charging handle it will help keep your fingers from getting wedged between the charging handle latch and the left sided forward assist .
I added a extended latch on one of mine to keep my finger from hitting the forward assist.
I don't do a whole lot of this, but I size and deprime them just like a fired case. I don't use the primers again. If this is reckless I'm sure someone will let us know.
My yellow primer loading tube tips would quit working also. Fortunately my 550 came with six of them and the last one worked now for a couple of years.
It matters a lot how large your 11 year old is I mentioned the 1187 youth 20 or 12ga earlier thinking about a small 11year old. But my daughter went with the 1301 also when she was 12 and it's been great. She was a bit bigger then most and loves recoil
My new springs with a gram follower did the same thing the other day. I had to bend the top coil till the follower sat at the exact angle in the mag like the old one's did.
