There are quite a few resources out there for us shade tree gunsmiths to work on our CZs, most notably this epic thread (http://www.czfirearms.us/index.php?topic=42537.0) I have linked to many times by David Milam of Cajun Gun Works. While tuning up a brand new SP01, I decided to take a stab at a comprehensive beginner's guide to these great pistols; my hope is that this thread will spark discussion and collaboration so that collective knowledge of this forum can create something really useful for new CZ lovers. The tools: I prefer a heavy hammer because it will deliver high energy blows without swinging it too hard (less effort = more control); you can cut down on "idiot marks" and other collateral damage when you swing the hammer with less effort. Because the pins in my Brownells set are too short for some applications I use these basic punches as well: although it looks like Brownells is now selling longer pins: http://www.brownells.com/gunsmith-tools-supplies/general-gunsmith-tools/punches/gunsmith-replaceable-pin-punch-set-prod545.aspx The replaceable pins are nice because punches do bend and they do break. You'll see I also use Quick Clamps with rubber boots which do a nice job of clamping the frame/slide down without marring the finish. By nature polishing metal is about removing metal, but the key is to remove very little amounts of metal at a time; I use a power sander with 1000-2000 grit sandpaper on flat parts and a felt wheel with automotive rubbing compound on those 'hard to reach' spots. As we become intimately familiar with our pistols, it's easy to become lax on safety, so I began by clearing the pistol. I tested the trigger pull for a baseline:
I'm very interested in buying a Tanfoglio Witness Hunter in 10mm. The only thing holding me back is i specifically want DA/SA not SAO. I understand the actions work essentially with the same parts, so I wonder could i add the interruptor to give it double action, or would it require more modifcations? I'm not even certain the hunter model has the same parts as the standard witness, but it seems probable. If i can put a witness interruptor in it that would be outstanding! If this isn't possible, or is highly impractical please let me know. If it is possible, please give me some details! I've never owned or handled one of these so i don't know their inner workings.
