Sounds like the OP might be interested in the NRA/Winchester Program or the Critters match at MPC. If he knew a member there he and his daughter could shoot as a guest.
There is a small difference in the stock shape and overall weight but accuracy should be about the same for either IMHO. I have read that the thicker barrel adds weight and improves barrel harmonics though I can't shoot good enough to test that out. Not sure how much it matters in .22LR any way...
I am just going to assume that none of those threaded barrels will fit a P-07 Duty and continue to wallow in my misery while still refusing to get my HQL for new purchases. Still I hope that one day I will get the email from CZ-USA stating that those barrels are in stock. I cannot hold out...
What are we shooting before 2PM since the pumpkins don't become targets after then? The high threat pumpkins? Gourds? I just want to know what I am shooting at from 10-2!
