A trigger boiled in spaghetti and chocolate chip bullets?
? Aren't you the venomous one. If you read my first post, all I offered up was an inexpensive and reversible solution to a common complaint about the fitment of the CZ 97 barrel bushing. I also commented on how awful the trigger pull was on this particular pistol. Nothing was said in that post about modifying the hammer and sear. Immediately, the boobirds and naysayers came out of the woodwork. Once again, the warnings about part hardness and such that I have heard for years were rolled out again. When I asked how about providing data info and specifics, you trolls had nothing! That's because you really know nothing specific about this subject. I certainly was not looking for a Nobel prize in gunsmithing for my bushing shim suggestion. Just thought I would pass along an idea that was worth a shot at trying. No more, no less. It is pretty obvious that this forum is run by a bunch of old trolls that are nothing but cheerleaders and shills for the aftermarket vendors that support this forum.
While we are on the subject of barrel bushings: Has anyone ever replaced the barrel bushing on a CZ 75 pre-b pistol? These are the early ones with the miniscule staked on front sight. This subject has been brought up, but no one seems to know much about this. I have seen some misinformation posted. Perhaps I can shed some light on this subject. I mentioned earlier that I had an early Action Arms import that while a big step up from the Tanfo's that I had experience with, was still somewhat loosey goosey in the tolerance dept. After I tightened up the sear cage to frame fit and modified the hammer to my liking, I wondered what could be done to address that sloppy barrel bushing. Action Arms had no small parts available, but I did get a tip that there was a gunsmith in Canada that worked with Pragotrade and had access to lots of CZ factory parts. His name was Tim Luckhart. I contacted him and sure enough barrel bushings were available. I purchased a pair of these on 3-04-94(I am reading from my original parts invoice). He listed them as cz oversize barrel bushing, but they actually have an undersized ID and must be reamed to fit your barrel. My original barrel had an OD of .502. My remaining barrel bushing has an ID of .475. So you see, they must be reamed for a good fit. Here is the installation procedure.......yo parrabelly boy, sit up and pay attention 'cause school is now in session:
The oem bushing has threads that screw into the slide. You must remove the front sight to start(more about the front sight in a bit). Put your slide in a padded vise with the barrel out and the muzzle up. You then use a large EZ out to simply uncrew the bushing in a counterclockwise direction. Mine came out easy peazy, but on guns that are pushing 30+ years old, one might want to soak the end of the slide in some Kroil or some other penetrating oil for a while before twisting the bushing out. The new bushing is machined extra long with two slots at the end to enable a tool to gain purchase of the bushing. You could use a large screwdriver, but I made a tool from a bolt and nut to evenly torque it down. Start it by hand and be sure not to crossthread the bushing. Once it is torqued down to the face of the slide, all that remains is to trim it down to length. I filed it down at first, then finished it with a 90 degree crown cutter to get it where I wanted it. All that remains is to ream the bushing to fit your barrel. This made a big improvement in accuracy in this pistol. As I have no plans to rehab another old CZ 75, I am thinking about putting this one bushing on Gunbroker for someone else's project. This is not really a tutorial, but I am thinking this may help fill in the blanks on these pre-b pistols. By the way, the part # for this replacement bushing is PFAP10191. I do not think they are still available, but you never know!
