I keep my match magazines separate from my practice/dry fire mags. I have over 16K rds through two guns as of today. Mostly practice. So far no magazine related issues. I use Grams springs and followers together with the CZC mag pads. I tried to use the CZC springs and followers but never was able not adjust them to make them work. With all due respect, CZC springs and followers are not ready to go. Frustrated from screwing around with them, I switched to Grams and never had any issues.
Having said that, I would buy Mec Gar mags for TS immediately if they were available. I have run them with my production guns for 60-70K without any replacements and problems.
I am not sure if the original TS mags are able to sustain that heavy usage.
