Most Browning Hipower barrels were 2 piece, and show a little seam right where your is.
Looks weird the first time you notice it.
I think these pictures tell me that I have a problem. Is looks like a fracture to me. just in front of the lug and about where the cartridge case would head space.
I purchased this for my dad about 1973. With the gun purchase I also purchase a box (50) of Browning 115 gr
ball ammo. Dad hadn't shot half the box. Dad passed away in 2007 that is how I ended up with this. I shot 2 mags of "hand loads' through it. 6.0gr of Unique and 115 gr HP. Extremely accurate, too.
I'm 50 yards from a machine shop. I'm going to walk it down and have them confirm, then....start looking for a replacement barrel. Odd, I think because I didn't think that the hand load was anything over +P performance.
Edited: Machinist confirmed....Split

Oh man!!! Wrench! Thanks! thanks for the education.!!! Yeeha!
Well, your load is fairly hot, but shouldn't be at a level that would break the gun.
My High Power (50699) shows no sign or indication of a two piece barrel, so that is a later innovation. Looks to have proper proofs. I'd suggest getting confirmation of it being a two piece construction - Magnaflux, dye penetration, radiograpghic exam - before doing more shooting. Just my paranoia, I suppose.

doggonit Clyde!! chuckle. The machinst comment was....."it looks like a split BUT it's really straight".
I might give Browning a call with a cereal (:0)number and see what they have to say. I won't shoot it til I get
It's made that way because its much easier and cheaper to machine the barrel from drawn steel tubing, machining it to size and cutting the top lugs, then brazing it into a forged breech and bottom lug. It's as least as strong as a 1 piece because there are fewer things to go wrong than in a 1 piece machined forging. Here's a post from Jim Keenan on the 1911Forum.com:
Barrels for the 1911 type have traditionally been forged to rough shape, then machined to final shape, drilled and rifled. That, as you gather, is a very expensive process. A cheaper method is to make the barrel two piece, using a piece of high quality steel tubing as the barrel itself.
There are two ways to make a 2-piece barrel. One is to make the rear of the barrel as a forged or machined block, with the lower lug as part of it. The block is then drilled out and the barrel tube, with the top lugs cut into it, is inserted into the block. Induction brazed together, that makes a pretty strong setup and has been used by FN in the Browning High Power for many years. I consider that type the equal to a one piece forged barrel.
The other way is to make the barrel from a tube, then weld on the lower lug. This is a much weaker arrangement, and I have seen some with the lug peeling off. I would not own a pistol with that kind of barrel and, if I had one, would immediately replace the barrel with the one-piece type.

My Argentine Hi-Power has the exact same seam on the barrel. It didn't "appear" until I had well over 15,000 rds through the pistol. I too was a bit concerned (not knowing any better) until I handled a few dozen Hi-Powers at gun shows and they all had the same seam.
6.5 grains of Unique has been my standard load for 25 years. Just happens to be the same amount of Unique I use in the 45ACP too. Saves time not having to readjust the equipment. Never had any problems with the load. Not what I'd call +P either. Very accurate, though.
