function once installed is correct but the install was fiddly because the roll pin holes were a touch undersized on mine. had to chase them lightly with a pin punch to seat the pin. once in, no movement
B5 polymer guard, locked to the lower with a roll pin. integrated lower contour gives a flush look. lighter than aluminum which is the appeal for a polymer build
B5 Systems trigger guard is well machined but the install was a bit fiddly because the roll pin required a specific punch size to avoid marring the polymer body. Once installed it sits flush. Larger interior than mil-spec for gloves.
B5 Systems trigger guard is well machined but expensive for what it is - basically a milspec replacement with their logo. Polymer is dense. Roll pin install was standard. Functions fine, the price is the issue.
