Finally joined a range (target sports) after owning my guns for three years. Anyone have any issues breaking in a hk sfp9 with 115gr? Bought 1000 rounds then I happen to read it should be broken in with 124gr. Who the hell even knew this was a thing.
 
Sell the pistol for something that will shoot anything. Joking aside, it should eat anything you decide to put through it. Clean, lube, shoot, repeat .
 
My hk p30 needed stiff loads for a few hundred rounds or I would get the occasional stove pipe. After that not a single issue. My sfp9 ran like a top from day 1
 
If you don't load your ammo, buy a box of each bullet weight (115, 124 & 147) from as many different makers as possible. You might find 4 different makers of 115.

Shoot from a sandbag and find out which ammo shoot the best group and the elevation level with the bull. (You can always move the sight left or right).

You may be surprised at how some ammo shoots much better in your gun compared to others.

By the time you test a dozen different boxes of ammo, your pistol will be broken in.

I'm pretty sure I also read the p30 specifically says in the user manual to break in with 124gr. I checked my manual for the sfp9 and it doesn't mention anything about bullet weight. I always thought the only difference between the two was hammer VS striker.

This is a forum about firearms. Using correct nomenclature is important, otherwise what we say can be confusing.

If you don't load ammo, you don't need any bullets. I think what you mean is you can't have too much ammunition.

Any time ammo gets down to around $200/1000, buy a few cases. Unlike gold, it will never lose value.

ugh. Can i request an eye roll emoji for the forum?
 
HK's are sprung for heavier recoiling 9mm like 9mm NATO rounds.

On my P2000 I had a few bobbles with 115 gr at first. I used 124 and 147 gr to 'break in the spring'. After about 500 rounds, it ran just fine, even with 115 gr ammo.
I suspect, if you just shot a bunch of 115 gr until it breaks in, that should work too.
