Are they the 6 round mag or the 7 round? My Extreme came with one 6 and one 7. No problem loading the 7 have not tried the 6 yet.

6 round

Have you tried using a speed loader. I have a universal one and it works great on mags that are difficult to load.

I use a speed loader most of the time, but have gone to the range and forgotten it and after loading those mags with 50 or more rounds by hand, your hands will let you know not to forget the loader again. Not a problem with any of my other 10 or so semi autos, just the P938.

I found the same thing on my Extreme. Both 6 and 7 are very stiff, much harder than my Ruger. My buddy bought a Glock 19 and he was loading both 15 round mags faster than I was loading one of mine. Although, he said his Kimber Solo was pretty stiff as well. I agree with the 50 round comment.

I loaded both mags and am hoping the spring will lessen under constant pressure.

My Ruger Speed Loader is a little sloppy, but looks like it will work. Didn't have it when we went to the range, as we went right after purchasing. His Glock Speed Loader was too sloppy for the single stack, and he didn't even use it for loading his magazine.

What I did like was how the P938 shot! Feels great, no problems, right out of the box.

Have not found a single stack loader. Seeing some of the new thumb loaders, anyone have any experience with these on a single stack?

Sorry: It won't.
A brand new spring will "take a set," after its first use. That is, it will become a small percent shorter than its length new. But it won't lose any strength.
Springs lose strength only after repeated flexings: in a pistol magazine's case, after repeated loading and unloading.
Merely leaving a magazine loaded will accomplish nothing.

Guess I need to start shooting it a lot!
Thanks.

I have checked into it and the upLULA with the new insert for single stack looks like the way to go.
Some Youtube videos of guys throwing rounds into mags at an incredible rate.

Thanks.

I've never had that problem with mine. Sorry... no help.

I just got a new Shield. The gun is hard to rack and the magazines are very difficult to hand load. I opened the magazines and checked out the springs. After fooling with them I decided to cut off several turns of the springs using a Dremel tool wheel. It is better and I can load the first few rounds by hand with no problem - but I still can't load it to full capacity by hand. I have ordered a magazine loader.

While you're at it, you had better buy some new magazine springs.
When you hacked off some spring length with your trusty Dremel, you set the magazines to misfeed and jam up your pistol.
I strongly suggest that you not place a life dependency upon that pistol, until you replace those magazine springs.


The Dremel tool is a trap for unwary beginning gunsmiths. It can make drastic, harmful changes with all too little effort.
