  1. Maybe THIS is what JP was talking about? Very low power factor rounds one after another, not even realizing the rounds never leave barrel? JP Enterprises out of Hugo, Minnesota, posted a picture of a 9×19 mm barrel cut in half.
  2. Yes.....she's a big shooting enthusiast. Shoots her mouth off all the time.
  3. I shoot open too. Once, shooting open thru a port, with no-shoot stapled on top of port, the comp. blast ripped cardboard in half. The forces are dramatically different with open pistol. Ideally (theoretically) the compensating forces should be much less with a pcc since they are acting on a leveraged position - the end of long barrel.
  4. I tried two wraps of paper around comp, secured with bit blue painters tape. gmr15 Took 3 shots before gases from comp blew paper apart. Conclusion: Compensator forces are absolutely nil.
  5. Don't forget that we have 26 ounces of mag&ammo hanging off the gun in front of trigger, when starting a 32 round stage. By the end of the stage, a lot has changed in the way of weight distribution. Personally a few ounces less on the handguard doesn't seem to make much difference to me all things considered.
  6. Winchester primers are 25% rebate right now. https://winchester.com/Rebates/2019-Winchester-Primers-Rebate
  7. FYI......some super soft loads, 122 PF, will not cycle the JP GMR15. About one in 40 rounds will not fully cycle the gun. So if yer wondering how low you can go......
  8. Not all that happy with magwell choices out there for pcc. Going to make one out of black Delrin.......should look ugly. What I want is a really huge mouth .
  9. Skip to 7:50 ......What handguard is this? I dont see it offered by JP yet.
  10. Sort of related to this topic...... Is there any significant use of 9mm PCC in law enforcement? . Not that I have any decent information, but my guess is its very low and not growing. Just wondering since PCC makers will make to the expected needs of the market
  11. I thinks thats just "copy and paste" from their AR15 equipment manuals. Still I did it.
  12. More specs would be nice. They dont list much. 16 in barrel with removable comp I assume?
  13. Little Loctite will fix it up real good.
  14. 122 PF out a stock JP GMR15 would fail to cycle about one in fifty.
  15. Its that donut of buildup right at the barrel crown that gets me. I just leave alone. Dont want to scratch things up picking at it with tools. PCC still hits steel plates at 100yds all day long.
