Other than the Radian Afterburner system that I tried for my P365, the C-1 slide for my Micro Dagger is my first built in comped version pistol. I have a few cases of Blazer Brass 115 grainers and the boxes state not to be used in ported and comped pistols due to the thin plated bullets. I can see an issue with a ported barrel having direct contact with the bullet but the comp opening on the C-1 slide doesn’t seem to be an issue to me. There’s plenty of clearance for no direct contact. Eye protection is always worn. I sold the Radian as the increased noise was too much for the slight reduction in recoil and muzzle flip. The C-1 doesn’t seem to have any additional noise.
On a different note, both my standard length and C-1 slides were in excellent new condition and did not show any evidence of being test fired.
