Got my franken P07 back a few weeks ago but didn't have time to hit the range. Used CZ Custom upper half with used frame and Cajun guts. Wasn't happy with the groups I was getting with the stock barrel and a suppressor barrel. Sent it to Primary Machine as they did great work on my P09, which drives tacks with stock barrel and Holosun 507c. Had them throw in a match barrel, compensator, and mill for my Trijicon RM06 with tungsten cerakote. Came back in two weeks and looks and shoots great.
Need to test the barrel with some other loads to see if it likes them as well. OAL was 1.09
Notes on paper are powder, amount, avg velocity of 5, and SD
