pretty sure that is a 94 style handguard not a 89 that fits it. you could put it on with a spacer or just use a wide forearm like from a 53 on it. don't put a vert grip on it unless it is nfa good.Maybe I shouldn't try to take it off...lol. I wanted to see if I could slip my SP89 handguard onto the pistol without the flash hider. I don't think it will, but was bored and thought I would try.
