**Disclaimer: As with all competition geared changes, always make sure you test and check your gear before you take it to a competition setting.  With 140mm/170mm magazine configurations especially, check the magazine in a USPSA 140mm/170mm gauge to make sure it fits.  With mass produced items like magazines, sometimes they can vary slightly from one to the next, often in the magazine lips that connect with the magazine extension/basepad.
