  1. When all is said and done I agree with Idahoaashooter. I had an older Tang (witness) open gun that I loved but parts are harder to come by. Not impossible by any means but when you compare it to a 2011 there is no comparison in availability. What FTP_Shooting_Sports mentioned about how the CZ/Tang design works is correct, which correlates to the barrel/link, slide stop pin and fit to the frame and barrel is so critical if not fit perfectly, while using it as a competition gun, will most likely cause the problems he mentioned. To be fair there is a friend of mine who's been shooting his Checkmate for a few years now regularly and as far as I know it's been reliable for him. I switched to a 2011 open gun a few years ago and could not be happier. Good luck

    Thumb Rest

    I never understood how close the thumb rests were, going on the same context as what slide4949 said: so I found this from Roy Neal, a knurled rest, he's a member here on be.com It allowed me to place it as far forward as I liked. It may even be one more hole forward now (based on the holes in the site mount), this is from a picture taken two years ago and i don't have my gun in front of me to verify.
  3. here is some old text from Jim Anglin, explaining what I mentioned. Below that is a thread with pics, explaining basically the same thing. Lastly, Atlas has a youtube video about the same context on STI mags, although what they don't show is the need to keep the tube shape "square'd". Start squeezing the tube too much and you'll ruin it. Ya need to get the second round over under the top round, the second round in the mag supports the top round, if the second round is off to one side the top round will nose dive. Take to pieces of round plastic 1/4" in dia tape these two pieces into the groove at the top of the mag, then take a small clamp with two pieces of wood cut the same width as the mag and clamp these two pieces of wood to the front and back of the mag. Dont put any more pressure on the clamp than it takes to hold the wood strips in place. Put the mag with this set up attached to it in a vise and squeeze the top of the mag together while watching the second round(go slow!) when it moves over under the top round some release the pressure and note if the second round has moved more under the top round thanwhen ya started, keep doing this till you have the second round pretty much under the top round, then put three rounds in the mag repeat and then four rounds and repeat. check how your mag feeds now with no recoil spring in the gun, when ya have it right the round should go into battery with just thumb pressure on the back of the slide. Only do this with a grams follower and spring set up if ya do this with the stock follower you will bend heck out of your mag and ruin it. Jim/Pa Sailors
  4. The nose dives are most likely a problem with the tubes being too wide at the double stack to single stack transition. Tighten that up some and those problems will most likely go away. Do some searching, you’ll find posts that more fully explain how to do it. the space at the bottom of the tubes can be helped by smoothing the control ribs transition at the bottom. They are not typically “smooth” or “flat “ enough so the follower can get caught there. File, sand, make it a smoother transition. good luck
  5. Sounds like the double to single stack transition area is too wide, needs to be squeezed together some
  6. I found no problems with using it in my 650
  7. I tried it, it worked but I like vv350 better. In my open gun(38sc) it took over 9 grains to make major with 124/125 grain bullets. Not saying it’s a lot of powder, there was still room in the case, just took at least that much. TruBlue seemed to be the same powder with the same results. i was more curious to see would it be viable to use if I couldn’t get vv as imr blue or trublue I could find locally good luck
  8. sounds like two things, both mean the tube(s) are out of spec. 1. the double to single stack transition has gotten too wide, causing the rounds to not come up into a nice single stack as they near the top of the tube. There are videos on youtube about this and images here on be.com of how to squeeze this area in a vice. It's easy but it's just as easy to completely mess up the tube. If you are not mechanically inclined I would not attempt this. 2. the follower getting stuck in the tube is a symptom of the main area of the tube has gotten too wide and needs to be squeezed back down some. The ideal width between the control ribs inside the tube is 0.740” for typ. Reloaded ammo, no narrower than 0.730”, no wider than 0.765” and keep tube square. Too narrow left to right and there is less capacity. Too wide left to right and the rounds can start to stack incorrectly and bind on each other. Squeezing a tube in a smooth face vise is doable, but if needing to squeeze it you have to go further than what is needed for the metal to take a new shape. Need to be very careful. If you are not mechanically inclined I would not attempt this.
  9. It's the extractor tension that is off. Since you have an Aftec on the way it is NOT UNUSUAL to have to fit them to each gun, they are almost never a drop-in part. A lot of folks love them, some don't. I've always felt they were a solution to a problem that does not exist but that's just me. If the gun with the current extractor does not appear to be broken (the extractor) why not just re-tension it first? Also, I would suspect your jams happen more frequently with a big stick than it does with your 140's. Extractor tension problems start rearing their ugly head first using big sticks but when it gets bad enough it will give you fits in all size magazines. good luck, hope it all works out
  10. I tried AA 38sc ammo a few years ago and oddly enough it’s the only ammo I’ve ever shot out of my open gun where I experienced light strikes. It was about one out of every 100 rounds. They seem to be a reputable company so it had to be something on my end.
  11. had someone tell me once to hammer the bottom of the racker a little to flatten out the metal so that it becomes a little snugger in the dovetail
  12. That and does it do it with any magazine length or just big sticks?
  13. grams followers and springs are of his design from a long time ago(20+ years) taran followers are from when he purchased everything from Bolen and later when he imitated Grams follower design.
  14. what he said, Grams all the way
