Browning Hi Power Spring Help

[marksiwel]

So I got a New Spring for my Browning Hi Power Mk III 9mm. The new Spring is 18.5 Pounds.
SO when Shooting, I got several Stove Pipes, it wouldnt lock back after emptying the Magazine, and some Failures to feed. I was using Monarch Cheapo Ammo, Am I using to strong of a spring? Should I try a couple of Boxes of Ranger Nato Ammo? Does the Spring need some breaking in? Should I get a spring that isnt as strong?
A Side note, I've never had a Failure to Feed or any problems with this handgun, ever, over 2000 rounds without a problem.

Any help would be much appreciated

I believe that is the same type of spring I used. Had a real tough time getting it in the first time, but none of the problems you are having. Wish I could help.

You are using too strong of a spring with cheap/standard ammo.

Stock Spring on the BHP is 17 pounds and that is what you should use for range work (standard loads......).

The 18.5 pound spring is good for +P and +P+.

I have an 18.5 lb Wolf and a BufferTech buffer in my BHP MkIII. Most factory ammo is 115 WWB, I carry Remington 115 JHP +P. I also handload.

Zero malfunctions in well over 1000 rounds.

Could be the ammo.

Yeah but I've shot Monarch through it with the old springs, never a problem.

I'm gonna try some Ranger Ammo, and try out my Speer Gold Dots.

What are the advantages of a stronger spring?

[marksiwel]

You can shoot heavier loads and the frame takes less battering - too much, though, and you'll start getting smokestacks, misfeeds, etc because there's too much pressure for the slide to overcome using that particular load.

Good to know, you guys have been very helpfull.
I also have a heavy spring for my Browning in 40, its a 20 pound spring

As recommended by Steve Camp, I only use 18.5lb recoil springs:

I've not had any problems, but I only use handloads and occasionally factory SD loads.

Hello. Sounds like it may be too much for the Monarch ammunition you mention. I have also been getting similar complaints of current lots of Remington UMC 9mm FMJ ammunition being noticeably lightly-loaded as well, but only within the last year or so. Try your Monarch with the standard power 17-lb spring. I use the 18.5-lb spring with standard pressure ammunition (115 to 147-gr) with zero problems in several Hi Powers but have not fired any Monarch in a great while.

Best.
