I got this extended mag for my gen 2 model 21 and so far I haven't had any problems unloading the entire mag a fast as possible. Cheaper than factory mags by almost %50. Only strange thing I've noticed is a rattle in the mag after loading 10 rounds or more. Also wouldn't recommended leaving the mag loaded for extended periods of time. I plan on getting at least a few more. It is very fun to dump the entire magazine very quickly and recommend buying reloading materias and tools otherwise it will cost you around $10 per mag if using target rounds. If you like to shoot a lot you will spend more on ammunition than the cost of your pistol in no time.looking forward to testing the .40 drum mag next.
