5 of 5 Glock 30SF July 13, 2022
Reviewer: Noah from Ga  
This clip does in fact fit my Glock 30 small frame gen 3 perfectly

i read where it said that it wouldn’t fit SF after i bought it a couple of days later and then when i took it out the package and put it straight in my gun it fit and i was very pleased!!! i would recommend taking the part in the description out where it says “doesn’t fit SF” especially for the 30SF i could say

5 of 5 Best $23 i’ve ever spent October 5, 2021
Reviewer: Josh from Jacksonville, NC  
I bought 2 of these for my glock 30. At first i was pretty skeptical. Took them to the range & needless to say they both ran flawlessly with both FMJ rounds and hallowtips. They’re also VERY tough. I was very impressed, bought several more for my 9mm glocks.

5 of 5 CMMG Banshee .45ACP September 22, 2021
Reviewer: Dave Crousser from Idaho  
The mags I got would not fit into my brand new Banshee.  After a quick call to the company they offered to accept a return, no questions.  The customer service rep offered some advice to make a small modification to the mags so they will work in my Banshee, without voiding the warranty!!! Awesome!  A Dremel tool with a sanding drum did the trick in a few seconds.  Now all of my ETS mags engage flawlessly and function perfectly.  Outstanding product!  Evidently the ETS mag design is to accommodate older generation Glock pistols....CMMG makes firearms that are only certain model Glock compatible.  My new CMMG loves the slightly modified ETS mags in 45 acp!  The clear design is cool too.  I am certainly not a machinist but was able to make the mods easily!  I mounted a Sig red dot and a Liberty Can, one Bad@ss looking toy!

2 of 5 Not for CMMG Banshee April 23, 2021
Reviewer: Michael from OH  
Seem to be quality magazines, but these will not lock in to a CMMG Banshee in .45acp.  The slot for the mag catch is too skinny.  Quick measurement shows that a working magazine has a 8.33mm slot, these have a 7.97mm slot and won't engage.  Hopefully the vendor I bought them from will take a return.
