Kinda reminds me of the "lipstick on a pig" analogy....

I await the results of this project.
Huh, I never thought turd polishing would be so interesting.

Yeah yeah, you're all freakin' comedians.....
Update; Removing the mag disconnect is a breeze and improves the trigger action a bit. More at 11:00

I'm enjoying the updates. It's good to get more first hand experience with this gun.

Worked on it some more last night. This pistol is stoopid simple. It's incredible how Hi-Point actually designed it. It boggles the mind. I can't begin to explain how simple the design is on this gun.
From what I can tell;
Lightening the trigger pull may be as simple as reducing the spring tension under the sear. I have an assortment of springs from Brownell, will be trying this out this afternoon.
The excessive trigger travel (take-up?) might easily be remedied by
#1 Adding a small stop on the top of the trigger
#2 Shaving off part of the top of the sear, therefore necessitating less trigger travel to fire.
General trigger action may be slicked up simply by polishing the contact points between the stamped-steel sear cam and trigger assembly, as well as polishing the sides where these two pieces rub against the frame side.
The magazine release; I don't like it, feels a bit chinzy. With mine, you have to ram the mag in hard to completely engage the mag. Easily remedied with a minute dremeling on the mag itself.
I'm telling you, this gun is a blast to #### with. The design is so simple, even this old brain understands the principal of operation within seconds.
Will post pics tonite, befores & afters

B the way, should I start a new thread? I seem to be very adept at hyjacking threads (it's a curse, I'm sorry) If the author of this thread wishes, I'll start a new thread.
Ok, so this is what I was mentioning earlier...
This the trigger transfer bar which actuates the sear cam
This is what it actuates, the sear;
The spring below the sear is quite high in tension. Changing it out using one with a lower tension would logically reduce trigger pull weight...
I started by polishing both of the sear cam sides as well as the contact point between the sear cam and the trigger transfer bar (the doohickey which actuates the sear cam). I also polished the respective contact point on the trigger transfer bar as well as the underside of this transfer bar (both rest and therefore rub against the shiny & smooth surface of the frame)
This is what it looks like reassembled;
I thought I'd overdone it with the Picasso thing. By Picasso, I mean that I re-radiused the sear cam contact area where it's actuated by the trigger transfer bar. As a result, the trigger creep was substantially reduced (80%) but the trigger pull was higher than before. And that's after swapping in a softer sear spring.
But after a 10-20 dry-fires, the trigger pull lightened up considerably. I'm going to go out and purchase a trigger weight scale so as to not pull #'s outta my butt anymore.
I'm also going to polish the contact sufaces on the sear where it holds back the firing pin. This may help reduce trigger pull even more. And remember now, I haven't actually tried it on the range. The reduced sear spring tenion may very well cause problems for me when actually firing it.
Remember now, I'm no gunsmith, not even a novice. If anyone has any suggestions or tips, I'm open to them. All except for putting lipstick on it LOLOL

Hey! Good post, Peter. I just got around to taking mine apart tonight. I figured not much going on, so why not?
I wanted to oil the hell out of this thing because I thought that the slide wasn't moving very freely when I went to shoot it the first time (7 FTF's in in 140 rounds). So I took out that pin that is exposed when the slide is racked and pulled this pig apart. Overall, it was fairly easy to pull apart, so that was nice. I just used an appropriate sized drill bit.
This is what it looks like when it's all pulled apart. I oiled the snot out of it as I have intentions of never taking this thing apart ever again. When I went to put it back together, I had springs shooting out everywhere and metal bits hitting the floor. I think I found everything.........at least I didn't have any spare parts leftover after it was all together again.

You must have did something wrong, because everyone knows the factories always throw in at least one extra piece.

LOLOL
I polished the bottom setion of the slide to make for a smoother slide operation. I think it helped. BTW, that freakin' paint is cooked on there something fierce!
