I have a confession to make. This might cost me some followers, but here goes. I like Hi-Points. There, I said it. I especially like 3D printed Lo-Points because they're dirt cheap to put together from a Hi-Point parts kit. I have a whopping $50 in this gun(and $20 of that was the magazine, and $10 was shipping). Also, in a bit of irony, of all the 3D printed pistols I've made, this one has the nicest trigger by far.
I decided to dress up my Lo-Point a bit, because I can. It is purely a cosmetic dress-up piece for an already printed frame. My frame
is a Freeman1337 V2, it may fit original Hi-Point frames too, but I
can't confirm since I don't have one to test. It fits my frame with my
C9 parts kit, but YMMV. The inside of the "barrel" is sized for 3/4"
copper plumbing tube(available at any hardware store). It may be fine
without the copper tube installed, but the muzzle blast will probably
erode the plastic fairly quickly. You may need to file the magwell to
get drop free mags. The handguard piece gets glued to the bottom of the
magwell and the nose piece attaches to the Pic rail on the frame with
6-32 screws so that the nose is still removable(I've heard rumors of people who actually clean their Hi-Points and it needs to be removable to get the slide off the frame).
