hi-capa grips
 

does anyone know if these grips are the same?

PRIME Infinity Type Aluminum Grip for Marui Hi-Capa 5.1 GBB (Type B, Black)
PRIME Infinity Type Aluminum Grip for Marui Hi-Capa 5.1 GBB (Type B, Titan Black)

also, does anyone know if the silver TM hi-capa mags fit in these grips?
I ask this because they dont fit in this grip:

When u say don't fit, do you mean the grip is too right or that the baseplate prevents it from being fully inserted?

when i push the mag into the grip, it gets stuck. the grip is too tight and wont allow the mag to be inserted all the way. it goes in about half way to 3 quarters.

ive had two of these grips and its the same for both:

was wondering about the other three i mentioned because i thinking about making another build.

yeah. I heard that the AS grips are uber tight.

The Prime ones support those mags just fine. I have one of the Micro pocket ones installed on a 4.3. Bothe silver and black mags work on it, no prob.
the dimensions they use for the magazine catch however is different. It can only fit the mag catches that the kit comes with. Using other magcatches is a no go. They are simply too small....

These grips come out of the same factory, IIRC. But they have different dimensions to tell them apart.

thanks e-luder.

i was planning on black gun with silver controls. so i guess this grip is a no go. wanted my own custom silver mag catch.
