BCM gunfighter grip on colt lower

I always have to cut that tab off on the BCM grips.

I had no issues installing the Mod 3 on my Colt lower, perhaps I got lucky?

Which trigger guard do you have? I’m betting it is not MOE.

Correct I have the standard Colt factory trigger guard.

I don’t think MOE is standard, though it is certainly common.
