My sister bought her first pistol about a month ago. Under my advice she went with the pistol that felt the best regardless of cost, the HK P30 in 9mm.
Some basic info before I get into the issue
HK P30, 10rd mags(NY limit), Independence brand ammo 115gr standard load

Last weekend I took her out to get her started and work on some basics and build her comfort level. She only had one box of 50rds, included by the dealer for free. I wasn't there when she picked up the pistol otherwise I woul have told her to get more and a different brand.
We went through the whole box and had a few stove pipe jams. 3 of the 4 jams happens when she was shooting and the last happened when I shot it.
This concerned me because HK should be flawless out of the box. I've heard nothing but good about them for years.

So I'm trying to figure out possible causes, let me know if I'm on the right track.
First: crappy ammo. Independence is not the best from my own past experiences. I'm thinking some of the rounds were under powered and just didn't cycle the slide correctly.
Second: she was limp wristing and that lead to the short cycling. The time it jammed for me I was intentionally limp wristing it to try to induce the malfunction.
Third: the capicity limited mags somehow messed with the feeding and caused the jams.

So am I missing anything? Any known issues with the P30?

I've already ordered better ammo and my sis and I are going to split a case.

Try adjusting your grip.

In contrary to what many people say some guns need a break it time to wear in the springs and contacts.

All my Glock, hk, Kahrs needed it in one way or another. My gf got my Glock to jam twice in the first 100 rounds and nothing since then even limp writing. My P200SK jammed on the first mag and could be limp wristed jammed in the first 200. My USP could be limpwristed for a small period. Etc...

A dead giveaway of needing to be broken in is brass ejecting close to your face initially. All my new handguns do this at first. The engineers design these recoil springs to last 10000 rounds and if they put a spring that initially isn't stiff it won't last and won't handle +p loads well.

You can shoot more powerful ammo which will mask any issues and break the gun in at the same time. Or just manually cycle the slide 100 times and leave it locked back for a week.


That is completely normal behavior, especially with that independence ammo (blue and white box right). Once the gun is broken in it'll run cheap ammo like that no problem. For now maybe get a few boxes of 124gr full power or just deal with it.

I would guess underpowered ammo and limp wristing. Give it to an accomplished shooter and see if they have the same issue. If not ...

That's my guess. I'm 5k rounds deep through my P30 and not a single hiccup. Use some hotter ammo for first 50-100 rounds to stretch her legs. Hold her tight and firm

If that is the case, it is an ammo issue. Buy good ammo and I bet it all goes away. If the ammo is underpowered or crap, no matter what you do to the pistol it won't have enough energy to cycle correctly.

My Glock 17 did the same when new. Now it never does. Didnt have issues with my USP 45 but it was used

I like your style.
