  1. Yes, the trigger has worn "grooves" in the pin, and the hole in the trigger is not round anymore, it's visibly oval. I will try the S&W Forum as well, and contact S&W customer support to explore if there is a possibility to get a new trigger pivot pin. The finish of the gun is not an issue, club owned guns are not that sensitive in that aspect......
  2. Is there a home fix for a worn trigger pivot pin? I can feel two "groves" on the pin from the wear from the trigger, I can probably get a replacement trigger, but what to do with the pin? Since I reside at the "wrong side" of the Atlantic ocean, shipping the gun to S&W is probably a "no go"...... It's a S&W 629 in .44 Magnum, stainless, "no dash" gun at my club that I try to fix.
  3. 3. And, upon hearing Joe Jacobi of the 'Skin's say: "I'd run over my own mother to win the Super Bowl," Matt Millen of the Raiders said: "To win, I'd run over Joe's Mom, too."

    That is hilarious!
  5. Hej Henning, you have a VERY committed brother! that's "sick" in the most positive way I know....
  6. Why not use a bullet as check weight? With that all ususal variables are neglectable, it should not vary in weight from day to day.... That gives you an idea of how much the scale varies, or not.
  7. Pat, did you offer to help the poor storeowner out and take all of them off their hands? For a somewhat lower pricer of course...
  8. I use shims (from Brownells) between the frame and both trigger and hammer, the rubbing against the frame is reduced that way. I have not deared to angle up the hammer stud, but that is the way it is done by real gunsmith's. How they adress the trigger rubbing against the frame I don't know.
  9. Short answer: No. Outside the course of fire, a dropped gun is not an DQ, unless the shooter picks it up by himself. Stopping a gun from falling out of the holster can not be "unsafe gunhandling", and the shooter did not draw (or almost draw) the gun from the holster since he/she did not hold the gun in his/her hand. EDIT: I play with a different rule set.... IPSC rules defines "Draw" a bit differently: Draw (Drawing): The act of removing a handgun from it’s holster. A draw is deemed to have ended when the handgun has cleared the holster.
  10. Ok, thanks for the info. Anyone here with a broken Bo-Mar who could send me a sight blade perhaps...? Just in case you know...
  11. HI. I'm helping a friend to mill the rear sight blade notch wider and narrowing the front sight on a Colt 1911. Is it possible to remove the rear sight blade and re-fit it again without a new screw and nut, and is there replacement parts if we decide to go back to original width again?
  12. Short update. In my gun, 35 ounce hammer tension (force) is about the lowest I can go with reliable ignition of Federal SP (seated in my Dillon 550). I could probably go a bit lower if would I re-seat the primers with he hand tool I have, but that's to much work.. I will keep the 6 lb DA-pull, I really don't like to have a weaker rebound spring, I like to have my trigger finger pushed out by the rebound spring to keep me from short stroking... If I can get my hands on a replacment hammer I will try to bob the h-ll out of it (Carmonize it )and check if I can go lower on the hammer tension...
  13. Acronyms tend to become words sooner or later, think of laser, pc, cd, dvd just to name a few .... I liked " - I totally take back all those times I didn't want to nap when I was younger."
  14. Difference in felt recoil between ammo with the same weight bullet and velocity depends of the powder burn rate used in the loads. Commercial ammo manufacturers don't always use the same charge weight or even the same powder between production batches, they only check that pressure and velocity is according to specifications. "Top of the line ammo" is of course more consistent between batches, but even there you may feel differencies in recoil. The same ammo may also feel different in recoil and chrono different depending on ambient temperature, so it is not easy to use bought ammo as a reference, you might have to try different brands until you find something that is consistent.
  15. I don't think so, the chrono reacts to the difference in light when the bullet passes the sensor eye, so even if there is a difference between different bullets in light reflection or shape, it's the same difference over the start and stop sensor. I use a USPSA target (cardboard brown) placed on top of the sky screen pins to shade the sensors, that works fine and is always handy at the range. Wind is of course a problem......
  16. Hi all. I have used my 625 with stock hammer and a 6 lb DA-pull, with 2 lb. hammer tension. 3 lb of the DA-pull is from the trigger rebound spring. Now I have new brass with small pistol primer (Speer green ammo) and I wonder if I can go lower in DA-pull, to say 5 lb and only 1½ lb hammer tension? Or even lower? I have not bobbed the hammer since the spur is the small version and the hammer is chromed, so I think it will flake the chrome if I cut the hammer. I have used the trigger pull scale hooked on the hammer under the hammer nose to check hammer tension, slowly pulling the hammer to full cock
  17. Shooting Glock's from a Ransom Rest is useless beacuse the loose fit between slide and frame and the trigger moves the slide for every shot. Shooting with support and using the sights as best one can is the only way to check precision in my experience. The trigger design makes precision shooting difficult but not impossible and I can shoot 5 shot 25 yard groups in the 2-3 inch size from a two hand hold with Winchester white box without beeing a Glock specialist. With the ISSF one hand hold it gets more difficult due to the mushy trigger and the groups open up to 4-5 inches for me .... There is not much one can do to improve the precision, but the trigger design has been improved by many gun smith's, but how much they improve your group size is difficult to predict.
  18. There is no teaching involved, my two flat coated retrievers do like that in the back yard, and there is no slope, they just run and slide...
  19. On question 1: One procedural penalty if not shot at the target. Question 2 is whatever the written stage briefing states. I have done both unloaded starts and loaded starts at stages with the "empty chamber start". It relly does not matter since Revolver is a separate division. The gun is also nearly always to be "laying flat on the table", so you can not have the cylinder open, but I have seen RO's allowing the cylinder to be open and once even the gun upside down, resting on the open cylinder... Not all RO's know what to do when we revolver shooters arrive to the stage, and the written stage briefing is mostly written with pistols in mind... IPSC rule book 2009: 9.5.6 A competitor who fails to engage the front of each scoring target in a course of fire with at least one round will incur one procedural penalty per target for failure to engage the target, as well as appropriate penalties for misses (see Rule 10.2.7). Glossary: Shot: A bullet which passes completely through the barrel of a firearm. (Draft rule book 2012) Engage: Actually firing a shot at a target while aiming. Firing a shot at, but missing, a target is not a “failure to engage”. The malfunction of a gun or a round preventing the actual firing of a shot at or near a target (e.g. a squib, a broken firing pin etc.), is a "failure to engage".
  20. A OAL variance of +/- .004 is of no concern IF the bullet has some clearance of the groves in the barrel, "free flight, free bore" in the chamber AND you are not near maxumum powder charge för that bullet weight and powder. Seating the bullet deeper than maximum OAL (more than .040 deeper) is not unsafe provided you are not near maximum powder charge for that bullet weight and powder, and this is more an issue when using fast burning powders and maximum loads. Making short rounds may give you're gun feeding problems more likely than high pressure loads. But this is not true for all calibers out there, some calibers are more sensitive than other, 9x19mm is an example of a cartridge that is sensitive to bullet seating variations. Making a round longer than recommended OAL (more than .040 longer) may give the gun feeding problems also, and if making the round to long it may reduce the free bore to zero with high pressure peaks in the loads, especially if loading with fast burning powders. And then there is the issue of how long rounds can the magazine's take? The critical measure when speaking of OAL is the free bore in YOUR gun with the bullet you are loading. There are several ways to check your guns maximum cartridge OAL for a given bullet. I find the easiest way is to remove the barrel from the gun, drop the bullet into the chamber, keep some light pressure on it and measure the distance from the barrel end to the inserted bullet's tip. Then remove the bullet, reassemble the gun and measure again from the barrel end to the breech face of the slide when the slide is in battery. The difference between the two measures is the maximum cartridge OAL (zero free bore). Reduce this with at least .040 and you are on the safe side. There is no way of telling if this OAL is usable or even gives you best precision, that you have to try out your self. Some say that longer cartridges shoot better than short, but that you have to find out by trial end error.
  21. I don't trust gauges for an accurate reading, I use weights instead. The tricky part is still where on the trigger to apply the weight, especially with revolver triggers and other DA triggers which are curved. I use a trigger weight with a roller that rides on the trigger. The drawback is of course that you can only measure in preset steps according to the calibrated weights at hand.
