I was recently at the uspsa area 8 match and on Friday while I was walking stages I ran into a guy shooting a TSO and he was upset because he just got bumped to open because his mags with the CZC base pads did not fit the gauge. This encouraged me to check my own since I never had before. 3 of the 4 that I had failed as well. After having them checked by the match staff with the EGW gauge I had them checked with a DAA gauge that a vendor had with the same results. At this point several people were trying to help and come up with a solution. James with Atlas gunworks filed down the back corners of one mag in a effort to get them to clear. He stopped at a point and didn't want to take any more off, saying he was worried I might have feed issues. Unfortunately it wasn't enough to get the mag to pass the gauge. After this several people looked at the mags and it was determined that the 3 that failed had base pads that were longer and they had play in them where they slide on the magazine tube causing the COAL to be even longer then the one that did pass. I was basically told by CZC that it was what it was and they would reprogram the machine to fix this in the future but for the guys that got to shoot open and the rest of my matches, we are screwed. I basically have $300 of fairly new practice mags or open mags. Has anyone else experienced any issues like this and if so what did you do to correct it.
