At long last, BDM has released a usable Colt .22lr conversion mag. I see on their website they are up to GenIII. I am looking for any real user reviews of the mag's performance regarding FTF/FTE, magwell fit, etc. I have an old Colt conversion and the single 10rnd cig-pack magazine. It runs like a top, but I would like more mags for it, and BDM is the only option.

Does anyone here use the BDM Colt mags?
What has been your experience?
Did you have to make any mods to the mags to ensure fit or function?
What generation are your BDM Colt mags?

Thanks
