I just added a Glock 20 with adj. sights to my 10mm collection. I heard it mentioned somewhere on the internet that there is a company that offers 33 shot 9mm clips and 28 shot 45 clips for Glocks. What is the company? Do they make a 28 to 30 shot clip for the 10mm? If so how is the quality? Is there a website for the clips?

Howdy ! Scherer makes hi-cap for Glock and plus 2 extensions.
They claim capacity of 28, but I have never put more than 25 into them.
I have 4 of them. Two work fine and the other two still need some messing
with. I'll get around to it someday.

So, google up Scherer Glock 10mm magazines and have fun !

I can't find much information on the Scherer clips for the Glock 20 or 21. When I google Scherer I mostly just pull up old threads on different forums where people have asked questions about them. I can't find a web site for them at all...

You are right. I just looked and can't find any for 10mm. They are available
for 9mm, 40s&w and 45. Looks like Sherer doesn't make them anymore.

try looking for a magazine. A clip is something totally different and is not on your gun or any Glock for that matter.

I had already tried Scherer Magazine, Scherer Magazines , Scherer Clip and Scherer Clips on Google and there is just not much information. I did find one place that listed a 10mm 29 shot clip but of course it was sold out. I just figured I could find a website for the Scherer company. I guess not.

I have read some good things about scherer mags and some bad things,but mostly bad. no personal use except to hold one and it seem'd like a good mag. the last time I saw one for sale was a year ago at the tampa gun show. It was a .40 cal and they wanted $50 for it then. If you found one in 10mm,I bet you would'nt want it because of the price. Be happy with the 15 + 1. I would'nt want to carry any more than that because (1) it's heavy all day and(2) I hope it's enough to get the job done.

Maybe one day, we'll get some really hi capacity magazines for our Glock 20's but until then we'll probably have to buy MP5's and just have some fun.

Arredondo +5 floorplates turn a standard mag into a 20 round mag. They are well made. I have some for both my G-21, and my G-20.
The 21 mags have been fine for reliability, the 10mm have needed a little work, but i THINK i got it licked-the follower gets caught on the sharp inside corner on the bottom of the mag tube. I sanded this off, but have not yet tried them again. Others use thiese with no issues, so i think it was the particular mags i had, not the extensions themselves.

They are not cheap, but they also are not junk. I EDC'ed the 45 mags, and i will EDC the 10mm mags once i get the bugs worked out.

the chamfer job i did on the mag tubes seems to have done the trick. Last trip to the range the worked well. i need to put a few more rounds thru them before they become carry mags, but it looke like it will happen. Gotta love 20 rounds of 10mm.
