Title: Finally finished converting my glock 21 sf to 10mm
Post by: jasonheimerm on April 08 2016 11:19:10 PM MDT
Finally got it all together. Lone wolf barrel and slide. Burris fast fire iii.

Nothing quite like 18 rounds of 180gr gold dot 10mm underwood screaming out of a 6" barrel with a red dot to keep you on target ;)(http://uploads.tapatalk-cdn.com/20160409/5a528d0d8b87d033c1d1df9577200eef.jpg)

Maybe a silly question (never owned a 21, but two 20's), are the slides different? Bolt face and extractor different?

Never mind. LW slide.

NICE!!!!!

To answer the questions, they are different, the breach face and extractor. However, 10mm will function reliably in a G21 with a 10mm barrel, heavier RSA (accommodates the lighter G21 slide), and 10mm mags. This is with a later LCI extractor. Earlier non-LCI .45 extractors will cause extraction issues with 10mm.

Sweet. Thanks for taking time to answer. I never know when I see a great deal on a 21!
