Long term use of RA-Tech Glock CO2 Magazines
 

I have had a couple of these RA-Tech Glock CO2 mags for a while now, but haven't had a chance to use them yet. I'm a bit worried about increased wear on my KSC G17 due to the higher pressure gas over long term use. Can anybody who has used these mags for a while comment on long term reliability and performance? Thanks.
