Thanks Chuck,
That was the info I really needed.
BTW,
I love the P-07 SR I just got back from Primary with the Venom optic.
I want to look into both USPSA, and IDPA Carry Optics.
I shot 100 rounds yesterday; 50 WITHOUT the optic turned on; and once I got adjusted to the sight picture I was pleased how well the standard front Suppressor sight worked with the markings on the optic body to co-witness. I know you had mentioned this is another thread, and I concur that it really does work well. No need for a rear iron.
Honestly, I think I like this set-up at least as well if not better than my P-07 UG SR with DPP & rear iron.
Next step is to put them both to the test in competition.
Thanks again for your input.
