This has probably been asked before but,

I have a G21 2nd generation, and I have a chance to pick up a EFK Fire Dragon SS 10mm barrel.

Will this work without any other mods (except for the mags).

If so I better get my 21/20 up and shooting.

LWD used to offer a G21-10mm conversion. It is our experience they will fail to extract about 10% of the time. The majority of extraction problems were ammo related, none the less it is still a problem. In my opinion, 10% failure is too great an issue to ignore, and certainly time consuming when it comes to dealing with you the customer. We discontinued selling this conversion because of these issues. We advise our customers to simply switch top ends. This way you are assured 100% reliability.
