  1. Scientists have long assumed that the eyes undergo temporary blindness as they shift focal points, but a new study from Science Advances (https://advances.sciencemag.org/) reveals that your eyes absorb key visual information during this time. Link to the paper: https://fcld.ly/384wkw9 Science Advances is a top tier peer-reviewed scientific journal.
  2. I had a blood test during a time when I was shooting a lot, both indoors and outdoors. I was not not reloading or handling spent brass, though. Lead levels were undetectable. My habits were: never touch face or food when shooting, wash hands and face immediately after shooting, and take a cool shower and change clothes when I arrive at home. So, it is certainly possible to eliminate lead exposure if you are just a shooter. Reloading is a different issue.
  3. No, recoil is momentum. No, supersonic bullets create a supersonic shock wave, subsonics don't do that. I agree though, generally the total energy (i.e. powder) is a better measure of "felt recoil".
  4. "Pick any caliber, and bullet weights to compare, and compute " That is exactly what i did in the OP
  5. In the OP I gave exact numbers from the Speer lawman line and compared 115 to 147 grain. The heavier Speer has more physical recoil but does feel "softer". I think this is all psychological: shooters reacting to supersonic blast and "feel" it is recoiling more.
  6. so, do you agree with my assessment that the so called "perceived recoil" is actually supersonic blast of the lighter 9mm bullets?
  7. When I was a beginner and shooting only factory ammo, I was told to stay away from lighter bullet weights like 115gr, and use 147gr because heavier rounds would recoil lighter. My experience confirmed this: 147gr rounds felt better and easier to control. Physics, however, tells us that recoil is momentum, and a heavier bullet at the same speed would generate larger recoil. So I compared momentum of a typical factory ammo like Speer lawman, at 115 and 147 grains. Based on factory specs, the momentum of the 147gr is actually larger than the 115gr, but by only about 5%. I do not think anybody can notice this difference in their hand, but even if they do, the heavier bullet should recoil more. This is contrary to what people feel. What I believe happens is that because the 115 grain bullet is actually supersonic, it creates blast that makes it feel more "snappy" vs. 147 grain is subsonic and doesnt create the same shock wave and the perceived snappiness.
  8. I twice had dead triggers with p320 line pistols; one time due to the tiny little springs under the sear breaking or coming loose, the other time the striker "hook" that engages the sear completely shearing off....i have several sigs and like them but the p320 line is not the most reliable pistols out there
  9. Once I compared my accuracy in bullseye shooting when target focused vs. front sight focused. I did not see much of a difference in 25 meter 5 shot groups. Perhaps front sight focus is a bit more accurate, but I think the difference would be negligible for action shooting. I think you can be 100% target focussed, with fuzzy front and rear sights, and still get your hits, provided that you are aware what is happening to the sights as you pull the trigger.
  10. At those distances you can pretty much point it and press the trigger, or use the window of the dot as a reference, and you will hit. I still struggle from time to time finding the dot when I am at awkward positions, but it is never a full second delay. When I lose the dot it is always high, so it just requires a quick downward adjustment.
  11. Same here. I am a dot shooter in competition but have seen many dots that fail and broke so I prefer irons for serious use, for now. When they become very robust and easier to install (and when my eye sight deteriorates), I will switch.
  12. Same here. I think the dot is better and easier for a beginner, for intermediate shooter, and for an advanced shooter. But, it is particularly better/preferable for a beginner. Which is exactly the opposite of what he says.

    X5 trigger work

    GrayGuns trigger is excellent. Installing it yourself is tricky, but doable. There used to be good videos on how to install, which would save you a lot of headache.

    Open vs CO

    comp? single action trigger? open holsters? non-moving optic?
  15. Nice gun. How does the grip texture feel on your skin?
  16. since that part does not reciprocate, it will reduce the ACCELERATION of both the upward and downward movement of the gun, and so it does not contribute to the dip the upward movement is caused by the recoil, downward movement is due to recoil spring
  17. For me, the dot covers too much for precision shooting. Nothing beats all black target sights and a 6 o'clock hold on a circular target. Extreme precision, because you are aligning a straight line (front post) and an arc (target), which intersect in a single point.
  18. I can do much better precision shooting with irons than the dot, but it has to be nice thin target style sights not the combat style thick ones. I agree that if you are certain of your shot calling, 1 shot should be enough if you hit the bullseye from 10 yards or further. What is the likelihood that you hit exactly where you are aiming, by chance? Very, very small. For this to happen, your trigger pull or sight picture should be off in a way to perfectly compensate the misaligned sights, which is very unlikely to happen.
  19. Let's say you are checking the zero of your gun. You want to shoot a group, but you hit the bullseye in the first shot. Do you need to continue shooting, or call it good?
  20. How about this: a nicer gun makes one shoot better. You are welcome.
  21. pull the trigger when the dot is somewhere on the A zone without worrying too much if you miss, its either your trigger pull, or you transition too early finally, dot need to be zeroed properly, and you have to think about height over bore issues for very small targets up close
  22. My two cents here. I have had good grip since the day I started shooting. Locking the wrist while being able to move my index finger fast comes natural to me. Recently I realized this is not the case for everyone and started analyzing the situation. For me, I believe it is due to my martial arts/boxing training. See, if you have to punch something like the heavy bag, especially without gloves, you have to have locked wrists. Otherwise you roll your wrist, and it hurts like hell. So, anybody who can punch a heavy bag without hurting themselves can lock their wrists at will. Funny thing is, your fingers can be quite loose while doing that, it doesn't matter as long as the wrist is locked. They can be loose most of the time, but at the time of impact the wrist becomes solid. Most boxing gloves force your hand to remain open and kind of loose. I am sure there are other sports have this kind of concept. Anyway, I recommend you try some heavy bag work and see if you get the concept.
  23. yeah, we always see the sights in follow up shots and never do double taps in competition, no matter the target size and distance....i'd say slow down and get your hits
  24. oh, finally, try the gas-pedal accelerator-pedal thumb rest (or whatever it is called), helps hugely with recoil reduction and control (yes, I said reduction!), and also helps you balance the gun on horizontal axis, helping eliminate that disgusting low left shot pattern (assuming you are right handed). there are a lot of things people wont admit here, and will tell you its all training and technique. while this is mostly true, the correct equipment helps you perform better, and this game is all about extracting the most performance out of our abilities
