hop bucking looks like a TM VSR/Pistol type. Glock 18C upgrade barrels have been reported to work. On a stock VP9 If you're finding it shooting low and under-hopping take apart the hop unit, wrap two or three snug wraps of Teflon tape over the hop area of the bucking and reassemble. it adds that much needed gap filling adjustment. I tried this with .25 gram bb's and the trajectory is nice, straight and on target with that oh so nice hop up climb and float now present with adjustment to spare. Problems reassembling? engage the slide catch rearward and press in the inner barrel back inside the outer barrel. This is for the tactical version (Gray) and it works every time.
