Ugh. I was at the range today shooting my CCW pistols and when shooting my P30SK with the 13 round magazine and P2000SK X-Grip adapter the magazine would come loose after first or second round fired. I bought another 13 round magazine and wanted to test it out today but it was happening with both 13 round magazines including the one that worked fine during two previous range trips. I tried swapping X-Grip adapters and do difference. Then I tried shooting the 13 round magazines without the X-Grip adapter and resting my pinky on the metal magazine body and still both came loose. I did not have any ten round magzines with me today to try out but plan on doing that next week. Both 13 round magazines came from HK Parts with flat base plate and sealed in factory HK plastic wrapper.

Has anyone else had a problem or success shooting their HK P30SK with the 13 round 9MM P2000/USP-C magazines??

Any particular part I should check or maybe replace? I bought my P30SK LEM new in April.

I really hope I can get this resolved and my P30SK with the 13 round magazine is the perfect CCW size for me. Not sure if HK can help as I am not sure if they officially state anywhere that the P30 SK can be used with the 13 round magazine.

EDIT: Problem resolved. It was position of my trigger finger on the trigger. See post 20 for details.

Thanks for any help, tips, or sharing of experience!

This is the 13 round magazine I am using.

I haven't had mine come loose, but I make absolute sure it's seated all the way in there which takes some effort with the x-grip. It's not a perfect fit and has to compress the rubber some. You REALLY gotta press them in there and be sure you hear/feel that locking in click. Mine are not stamped law enforcement only though.

Thanks for that. I give them a pretty good push with the palm of my hand and hear them click in and make sure I can't pull them out but I will have to try again next time and also take a couple ten rounders along to make sure they work fine. I was really surprised when I had the same problem not using the X-Grip adapter and just the bare 13 round magazine though.


EDIT:
I just spent some time looking at my P30SK and it might be my big fingers LOL. If I put too much finger on the trigger my trigger finger is just barely touching the magazine release as the trigger is pulled all the way back. I could see where during recoil just maybe my trigger finger might be actuating the magazine release. I have never had that happen on my VP9 or DA/SA P30L though but I put the large palm swells on them and never got around to doing that with the P30SK yet. Gosh I hope that is it.

Hope it is your fingers. That is disconcerting.

During my search for my new CCW ending up with a P30SK, I rented a S&W Shield 9mm.

Several times when I went to shoot, I ended up 'just' depressing the mag release enough to cause the disconnect to engage, and the gun would not fire.

As a lefty, apparently what was happening was I was gripping so hard as to compress the mag release. The Shield is not ambi-friendly, so I dropped it from my candidate list.

Hope you confirm the issue with your mags, grumpy1.

Sorry to hear about your experience with the Shield!

I bet it is my finger but that is a show stopper for me. I hope to get to the range within a week and try again and see what happens with the 10 round magazine which may not be an issue because when I grip with the 10 round magazine my pinky is under it and forcing it upward but that assumes I would have a two handed grip in a SD situation. But this is why we try out our CCW pistols LOL. Dang I really love this P30SK. Maybe I should look into a P2000 as the price is right on it these days but no one around here has one to handle to make sure I would not have the same issue.

If it is my trigger finger then for me that still is a problem because in a high stress situation I may not put the trigger finger where it works best and honestly more likely would not. Here are some photos showing my finger size and where it ends up in relation to the magazine release in a more normal trigger pull and then using almost the very tip of my finger.

I've had that happen shooting my HK45. Part of the reason I like the USP-style release more than the P30-style.
Thanks for sharing that. Helpful info!

Interesting situation, and I'm glad you found the cause of the problem. In the aviation world, that's called "Pilot Error"! Lol

Good pictures, very intriguing.

I have M hands; and with the M Backstrap (I'm a lefty also) here is where my finger is indexed on the trigger guard:



And this is on the trigger at the start of a normal press:



And this is pressed just before the break:



Like I said, it goes to show, how different we all are in hand size. Sometimes the gun just doesn't work.

Anyway, hope you get the problem figured out. :)

Well I am not certain yet but I am pretty sure. Won't know for sure until next range trip.

On my hk45 I hit the release. I need to work on my finger placement. As a lefty I love the Hk mag release, but it stinks to drop a mag on accident. It only happens when I shoot fast, definitely need practice.

Thanks for the feedback Jon. I have HK45 and P30LS but both DA/SA and 98 percent of the time shoot them in SA and never had the problem. My P30K is my first LEM and I really like it but I got to get more consistent on finger placement with it. If I just use the very tip of my finger when the trigger is fully forward that will probably work fine for me. I should find out by next range trip LOL.

Yes sir.

With luck, I should be at the Range Monday for my initial 100 or so rounds with the P30SK.

I have my carry Federal P9HST2, some Speer GD 124, and for range ammo I'll be using S&B 115 brass. I print my own targets; just a random assortment of NRA B8s, 3x5 cards, FAST targets, and a neat drill I like called "Finding Your Level".

I will keep an eye on the trigger; this will be my first experience with a LEM after 6k or so rounds with various Striker Fired pistols.

I have XXL size paws and have never hit the mag release on any of my HKs, including the P30sk.
I suggest trying different panels and backstraps until your finger ends up properly on the trigger from natural acquisition. You might need one side panel larger than the other with the large backstrap so that you find the correct grip for your paws. Then bring all the pieces with you for live fire try out. Live vs dry fire can vary in configurations.
I use mixed panels, a larger one for my palm and the largest of backstraps and instant acquisition is a constant for me.

Just back from the range. Completed 126 rounds through the P30SK; 0 malfunctions, 0 mag drops.

Very very smooth little pistol.

Glad to hear. How do you like LEM? I have some DA/SA SIGs and HKs and had no problem with the LEM P30SK and really like it for CCW with the comfort of thumb over hammer.

I like it, a lot. The P30SK with LEM was a big change from 2-3 years of shooting nothing but striker fire pistols, so it was kind of a leap of faith to buy one.

I found the whole LEM trigger complexity was vastly overblown, for me. Pull trigger: gun go bang. It really seems pretty straightforward. Plus, if you decide you don't want to shoot, simply release trigger and index on slide. The break is easy to find, every time; I did not have any trouble shooting, even in rapid fire strings. My accuracy (for me) was astonishing; I found it very easy to get the sight on target, and hold it, without any of the whole "staple gun" feel I get with SFA actions.

I had zero issues seeing the stock front sight. I sharpied the rears made them fade out; I don't see any need to get any different front sight for this pistol. Yes, they are not Trijicon HDs, but the greenish / yellow dot is easy to see and does retain "some" light.

Both 10 round neutered VP9 mags I bought worked fine, as did the 15 round VP9 mag. I noticed, though, with the extended mag tubes my pinky strong side was scrunched into the base of the grip, which was painful. I need to get some mags sleeves at a minimum.

The ergos on the P30SK seem to fit me very well; it felt very solid in my hand. I have M hands for a guy, and my pinky wrapped under. I'm on the fence about the HK pinky extension floor plate for the 10 round mags, as I did not really have any issues in accuracy. I have ordered an Xgrip sleeve and +0 pinky extension from www.hkparts.net.

Bottom line: I am loving this pistol. It feels good in my hand, points naturally and I can see the stock front sight easily. As a carry gun, with 10+1, I feel better than with my (sold) PPS M2 6+1. The trigger is smooth and easy to shoot. Really really really glad I bought it.

Here's one picture from the range session; it's a drill called "The Test". 10 rounds at 10 yards in 10 seconds on a B-8 repair center. For me, a score of 74 is doing well.

Glad you are liking your new P30SK and LEM is working out for you. My take on LEM is the same as yours. Nice shooting for ten seconds!

Well good news. I went to the range today with a couple HKs. My P30SK worked perfectly with the 13 round magazines. I tried both of them and loaded only five rounds at a time and then reloaded. I was more careful with my trigger finger placement. I think what might have happened last time is that I had some pain on my trigger finger from yard work on the right side at the bottom of the edge of the finger nail probably from debris getting under it. That has cleared up and I may have been unconsciously been putting more finger on the trigger than usual to minimize the pain. Not sure but that's my story I am sticking with. Anyhow I am very happy that is no longer a problem.

Last 15 rounds of the day at 7 yards shooting at at about a round per 1-2 seconds.
