Free Time+Milling Machine=FUN!!! Now with video
Got bored at work so I tore apart my FNP-9 and tossed it in the mill. Added serrations on the front, pocketed out the top (to drop a half ounce of reciprocating mass) polished the barrel (just for looks) and made a stainless steel guide rod to replace the slightly worn aluminum one, and add back the half ounce to the non-reciprocating frame.

I've never so seen that done before, how does it shoot now?

Not sure, I haven't been to the range yet, but there's a ton of Glock guys running competition with super lightened slides, check out zev glockwerks slides, I didn't want to get too drastic so I modeled it sorta more after the Springfield XDm, it's got serrations pretty much all over it and just a small window on top. Theoretically, having a lighter slide and adding weight to the frame you are making the reciprocating mass lower and the non-reciprocating mass heavier, which, theoretically, will make the gun stay on target better for faster follow-up shots. THEORETICALLY lol. I just wanted to change things up a bit and keep it interesting, if it actually improves follow-up, it's just a cool bonus. Plus I like racking the slide by grabbing the whole thing from the top, so figured a few more serrations wouldn't hurt. I'll definitely add more after a trip to the range.

That looks awesome...

There are quite a few ways to get tricky with it..

Dang now I want that STI 2011... Been itching for a 1911 to customize for a long time.

Now I want the slide on that second Glock.

I hate you Josh

Well got to do a tiny but of function testing today, fired a single round, then 3, then a full mag dump as fast as I could. Worked as good as I could hope, zero malfunctions, stayed on the paper with entire magazine. Slide seems to cycle much faster, with less effect on point of aim upon reacquisition. I like it! Now the real decision comes into play, do I bead blast the freshly machined portions, to make them match the original, or do I paint all of the serration valleys with black paint to match the factory black filled engravings of the slide? Decisions, decisions... Also my next point of business is gonna be cut to fit grip tape I think...

sunofnun 08-13-2014 10:47 AM

Tough choice.. I think they could both look cool..

I'd bead/sand blast first.. if you don't like it.. cerakote?

DaveyG 08-13-2014 03:24 PM

But I'm a big huge fan of contrast... I had thought of polishing the flat sides of the slide so the grooves of the factory serrations would be matte, the grooves of the added serrations would be shiny, so it'd have a matte/polished contrast, but in afraid that would look too busy, as the factory lettering is black, and frame is obviously black, so I thought maybe black and matte contrast would be better, with the only polished parts being internal... Any pics of a black/matte/polished pistol out in googleland? (Off to search...)

Agreed, I never thought I'd be looking at a Glock and thinking it was really cool.

sunofnun 08-14-2014 08:22 AM

Ha ha..

Google image search custom glock slide... (I don't like them either.. but there are some dead sexy pistolas out there..)

OR..... custom XD Slide / Custom 1911 SLide etc

Yesterday's shooting fun with the modded pistol:

Did my tungsten carbide guide rod yesterday, just for kicks n giggles. I figure an extra ounce (or less) in the grip wouldn't be a bad thing. Pics to come this evening.

RK600 08-27-2014 02:37 PM

Interesting...I know tungsten-carbide is very strong and scracth resistant but it is also prone to breaks as it has almost no flex. Under stress, it will crack and fracture. Will that be an issue here? I'm not 100% familiar with the FN's but doesn't the slide ride on the guide rod?

DaveyG 08-27-2014 07:13 PM

Sorta. I'm not too worried about it though as the factory original piece is aluminum on the FNP, and the only spot that was showing any wear was the very front where it stepped up in diameter. I figure if the competition Glock guys can run carbide guide rods, why can't I? Lol and mine I used stainless ferrules on the ends, where the only impact points are. I'll try it out and worst case scenario I'll make another one outta stainless.
