predictive text can go die
There's a few ok areas regarding the topology, but looking at the back of that bullet cylinder, i have to avert my eyes, also, there's way more loops on the grip than needed to hold that form, some triangles and a massive pole, as well as the unevenness of the poly sizes, mainly due to you having so many loops for the finger arches, its not a bad attempt but there's definitely plenty of room for improvement , I'd start off with what my homie CBR suggested, and see how you go from there :D
