A YouTube video on the CWA/Precision Defense pistols mentioned that 15-round mags were coming out this fall from GSG and I just found them on sale at about 4 different online retailers. I ordered 4 of them and will report back as to their reliability with the CWA and whether you still need Chet's baseplates to get past the mag funnel.

Received the new 15-round GSG magazines.

As you can see, the mag body is the same (GSG 15-round on the left, GSG 10-round on the right)

Next photo is magazine followers and magazine bases. The new GSG 15-round on the left, Taylor Tactical in the middle, and GSG 10-round on the right. As you can see, the GSG 15-round and the Taylor Tactical are nearly identical for the follower and base; except the GSG base is plastic and the Taylor Tactical is aluminum. Also, the GSG base is just a tiny bit (maybe 1/16 inch) taller than the Taylor Tactical and the slide stop catch on the follower is slightly different.

Next photo is magazine followers and magazine bases showing the inside of the bases. Order remains the same. Again, the GSG 15-round and Taylor Tactical are basically identical. Both use a set screw to secure to the mag body. The GSG 15-round takes a slightly larger Allen wrench than the Taylor Tactical.

Next photo is springs. The new GSG 15-round on the left, Taylor Tactical’s extra power spring in the middle, and GSG 10-round on the right. I think the GSG 15-round isn't as stiff as the TT extra power, although it's longer.

Next photo is the gun sitting flush on a table with the GSG 15-round magazine installed. Thus, it doesn’t hang below the magazine funnel.

I haven’t been to the range yet, but messed with combinations of stuff at home. The results:
  • I managed to get 16 rounds in the GSG 15-round magazine, but the top round may be too tight to function properly, so 15 rounds might be the right functioning number.
  • I swapped out the GSG 15-round base with one of Chet’s bases and managed to get 13-rounds in the magazine. I then also swapped the GSG 15-round spring with the GSG 10-round spring and was able to get 14-rounds in the magazine. Neither the 13 or 14-rounds seems too tight, so they might be functional.
Because the GSG 15-round magazine basically adds the equivalent of the Taylor Tactical upgrades, it has the same minor limitations (see
).

That said, messing with the Taylor Tactical magazine loader a bit, if I pay attention to the angle I press down, I can load the first two rounds, even thought the follower cockeyes a bit.

Now trying to decide which combination of springs and bases I want to test at the range. It can be a huge pain to remove Chet's bases so I hate to put one on unless I plan for it to stay. Will check back once I have a chance to test it.

Thanks For this write up!

Curious on the 13rd Rd config with a Chet base did that need care with loader for follower tilt?
Yes, the GSG follower tilts the same as Taylor Tactical. There is a small amount of play with the fit of the loader over the magazine when you first start loading rounds. If you angle it the right way, it will push the follower down so you can load the first round; I think once you get used to the angle that you need to push it down to get it to load, it can become second nature.

I'm taking a 15-round mag (unaltered) to the range and a second mag where I'm replacing the base with one of Chet's and the spring with a 10-round spring (which I think will be sufficient). We'll see what happens.

Went to the range last night. Interestingly, when loading magazines at the range, I didn’t experience any of the follower tilt I was experiencing when messing around with the magazines at home.

I took one stock 15-round magazine and was able to load 16 rounds in it every time. I shot 10 full magazines of 16 rounds (160 total) with no issues whatsoever.

I also took one magazine that had the 15-round follower, a magazine spring from a 10-round mag, and a Chet base pad, which I was able to fill with 14 rounds. I shot 10 full magazines of 14 rounds (140 total) with no issues whatsoever.

While I prefer Chet’s base pads because they extend below the mag well, it wasn’t as awkward as I thought it would be to insert magazines with the 15-round base pad, but your results could vary based on how you grab and insert it (and maybe how fat your palms are : ).

So, people have a lot of options depending on how many rounds you want in the magazine and whether you want the base pad to extend below the mag well. You can buy new 15-round magazines, you could buy just the followers from Taylor Tactical or Joe Bob Outfitters for use in your current 10-round magazines, or you can buy any other combination of components (base pads, springs, followers) from Taylor Tactical - depends on what you prefer and how much you want to spend. Keep in mind, that I haven’t shot as many magazines with the Taylor Tactical follower, but I don’t see why it wouldn’t be as reliable as the GSG follower.

I’ll probably primarily use the 14-round set-up above (using Chet’s base pads) but note that I don’t compete, just shooting for fun.
