    SAR K12 Sport - All the Upgrades

    in "Other" & Pistol Comparisons

    removed link to off-site auction per Forum Guidelines

    I’m actually selling a heavily upgraded version SAR K12 Sport on GunBroker right now: 

    My intention in sharing this is honestly not about selling it but capturing for posterity what upgrades work and which don’t, along with links to all the items. This has been a fun / crazy journey and want to give back to the community.

    First: a special shout out to Henning Wallgren (of Henning Group) who patiently helped me at various points on this journey, and who actually has a SAR K12 and could test fit certain items (rather than just guess).

    Main Points (I go into more detail later):
     

    • Most (not all) internal parts for the Tanfoglio Small Frame will work
      • Henning Group and Patriot Defense are a great source of upgrades for Tanfoglio
      • I’ve been told that it’s most similar to a Tanfoglio Witness Elite Limited, but I can’t confirm that
    • Magazines: takes standard CZ 75 magazines
    • Rear sight: EAA SUPER SIGHT (LPA/Bomar style)
    • Front sight: some weird Tanfo-specific thing (you’ll be surprised which Dawson front sight actually works… see below)



    What DIDN’T work (so you learn from my mistakes)

    • Henning Base pads on OEM SAR K12 mags
      • Issue: They will slide on but they will just pop right off when they hit the ground.
      • Easy solution: just buy regular Mec-Gar CZ75 mags and put the same Henning Base pads on those. They work perfectly.
    • Henning extended firing pin (H051-TL X-Long Firing Pin for Tanfoglio, HENNING GROUP - X-Long Firing Pin for Tanfoglio)
      • Issue: It would have required modification for both length and taper
      • Easy solution: Patriot Defense has one that just drops in
    • RedX Gear holster
      • Issue: really tight fit, and terrible customer service (that’s a whole saga in itself)
      • Easy solution: modify it or buy a different one (perhaps there are more options now?)



    What DID work (so you learn from my successes)

    INTERNALS


    EXTERNALS


    FYI… I worked with a gunsmith who is also a competition shooter who understands performance and tuning. In addition to installing and fitting all of these parts, he also

    • Chamfered outside edge of firing pin hole
    • Polished breech face and rails
    • Ramped and polished the feed ramp
    • Magwell: perfect blending of removal of any edges (see photo)
    • Overall polish and deburr
