I want to install a metal slide of my hicapa and was wondering if anyone can talk me through the steps of taking apart the innards of my gun so i don't screw it up. thanks for your help.

Just open up your manual and study it for awhile, then start working :P

Take your time with it, some parts are parts are easy to take out, and some your probably gonna go HUH....but take ur time and you'll get it eventually. Or take your gun to a local gunsmith, pay him some money and get the work done

the hicapa with a metal slide is awesome btw you'll love it

PM me or add me on MSN.

I've done it, there's a few things you should know and watch out for...

Tax: i read your thread and it sounded like the slide that you put on was a pain in the ass to install i was wondering if all slides for this gun are a pain to install or if it is PGC slides that are the problem?

Shooter's Design slides are pretty much hassle free to install.

My PGC slide was a simple fit. The only thing worth mentioning was that it fit AMAZINGLY tight to the frame. It took a good hour or two of working it in before it would cycle. I'm sure if I had sanded the slide or frame it would have gone easier but I didnt want to mess with it. Just as easy to lube it up and rack it for hours on end... talking about the gun that is...

I took my hicapa to a friend a few days ago and he noticed that the breech 'rails' quite often snag on the two little silver metal spring loaded dealies that are on the back
shaving the rails down so it is rounded prevented this snagging

[Anduril]

Oz, so you just racked your slide and lubed it until it cycled properly? cuz thats where I'm at right now, I'm thinking of getting some sand paper to sand it down, but I dont mind racking it for a few hours? lol but yah, the PGC slides are a really tight fit

[Matt_M]

I'm pretty sure Tru has a couple PGC slides in, i really don't want to go outside of the country to purchase on a slide because i don't want customs to rape my wallet. If you know anyone selling a shooter's design slide for the hicapa let me know.

if you tell me which one you want, i can bring it in for you.

What I was mentioning in the PM was the following:

- Field strip the gun,

- Pop the blowback chamber out of the gun (I don't recall if this requires removing a screw from the underside of the blowback chamber, but I know it doesn't require removing a screw from the rear sight, so don't bother doing that)

- Take out the blowback chamber
- Taking the blowback chamber out of the plastic slide requires you to flex the slide open where the blowback chamber will come out. Marui designed it with a 'lip' to hold the blowback chamber "up" inside the slide.

- take out the front sight, and the rear sight. It slides out to the side (I believe it only comes out in one direction...)

- take the blowback chamber and the rear sight and see how they 'fit' together while they're outside the gun. Notice the circular "notch" on the blowback chamber, and the cirular bump on the sight. They're a VERY tight fit. Keep this in mind

- Put the front sight in the new slide (so you don't forget)

- Slide the rear sight into the new slide (paying attention to whichever direction worked best coming out of the plastic slide)

- The blowback chamber should just slide up inside the new slide. (there's grooves for it, and you'll see where it's supposed to fit)

Might be a tight fit, require some tapping, or some working back and forth to clear out any excess metal. (shouldn't be too bad though)

- NOW: If you find that the blowback chamber WILL NOT QUITE SEAT FLUSH with the slide... You're not crazy! And it IS supposed to fit very nicely!

Don't leave it this way, or try too hard to put it on the gun now. Forcing things never works, and I got my slide stuck on my hi-capa so badly when I had it that I thought I destroyed the gun.

- Recall the notch/bump on the chamber/rear sight. If those two pieces are misaligned at all, it will cause the blowback chamber to not seat right at all.

My solution was to grind the bump off, but if you can sand it a bit, or re-align the parts so they fit, that is probably better.

After that, you're at the stage where you've got to rack the slide a bunch to get it to work smoothly.

I did this with a PGC slide, for anyone who's curious, and it was a bit frustrating, but once it was done and I worked the slide till it was smooth, it was an awesome addition to my gun. I also found that with a Tanio Koba piston cup and a recoil spring, the cyclic rate was really not noticeably affected. The Hi-Capa is an amazing gun.

hope all that helps.

without the circular nub on the breech, i find the rear sight gets a bit loose
not that its going to fall off, just rattles a bit when you shake the gun

To Andruril: Yup, I just drenched it in lube and tapped it on and off little by little until i could get it all the way on, then i just racked it over and over and over again, making sure that the slide went all the way back and all the way forward. I didnt put the guts in the slide until I had it decently broken in. It took a bit of sweat and could probably have been made easier by a bit of sanding but I was happy with the results. Just make sure to clean it all up after, your gun will be full of a sludgy grey mixture of lube and shavings.
