19 Upgrade Guide
Shing Yan L. (aka Guts80)

bare bones reliability upgrade for your KSC Glock 19? Here goes:

Metal slide + metal outer barrel
-real steel mag catch (will require some filing) OR a metal
mag catch (G&G’s alloy mag catch or Guarder’s steel mag

don’t need to get an upgraded recoil spring guide because the
OEM part is already metal :D (However if you DO want to get
a higher tension recoil spring…it usually comes with a metal
recoil spring guide too).

tell you the truth, the stock recoil spring is fine for the
metal slide + metal outer barrel (speaking from experience here…I’ve
installed the metal slide and outer barrel while keeping the
OEM recoil spring + guide on about 5 KSC G19s’ with no problems).
However it will be tad bit sluggish compared to a plastic slide
and outer barrel.

want a little more out of your gun now?…add these parts on.

piston head (yeah..it’s the PDI piston head for the 17/18C)
-Enhanced hammer spring

piston head as I’ve mentioned before gives a better seal thus
giving your more power/recoil. It also saves gas by creating
a more efficient system (slightly). However it also takes up
a bit more precious volume in the loading muzzle. But for what
it’s worth, it’s a good trade.

higher tension hammer spring is good to have if you play in
hot weather + use green gas. This will give the hammer the proper
amount of force to actuate the valve on the mag properly. It
will also give you a significantly stronger blow back and a
slight increase in FPS (installed a 150% Hidakaya hammer spring
on my G19. 40 FPS increase I’m estimating). You MIGHT need to
get a stiffer recoil spring to compensate for the stronger recoil,
but that’s really up to personal preference. Oh and btw, the
hammer spring is a bitch to install (check out a guide
). You should also be aware that it takes more power
(and in turn…gas) to cock the hammer again, thus gas efficency
will also go down.

you want the full blown upgrade? Add these too

enhanced touch-breech
-Firefly Rocket valve
-Hi-flow valve
-KM KSC Glock 17/18C tight bore

enhanced touch breech is just a more solid and robust version
of the OEM part. Personally speaking, I don’t think it’s really
needed, but if you want the utmost durability then get it by
all means.
The rocket valve, again, makes the system more efficient so
one will notice an increase in power and recoil (slightly).
However I’ve had heard reports that it’s a total b!tch to install;
can’t deny or confirm this.

hi-flow valve, hence its name, gives you an increase in gas
flow, upping the power and recoil (it’s installed on the mag,
so if you want the same power from all of your mags, you’ll
need to buy one for each mag…can be quite expensive). One
thing you will notice for sure is that gas mileage drops down
due to an increased use of gas per shot. Some have said that
the difference between the hi-flow valve and OEM valve are quite
significant, while others have said that the difference is almost
negligible. I’ve personally opted not to get one due to the
gas mileage issue (gas is expensive enough for me ><).

tight bore gives you tighter groupings, increased range, and
a slightly higher muzzle velocity. However the inner barrel
will protrude from the Glock 19 barrel a tad bit. To properly
hide the inner barrel, you’ll need to get the threaded Glock
19 barrel (I believe guarder makes them…but good luck trying
to find one to purchase online). On a personal note, I would
not really recommend tight bore barrel’s for pistols considering
A). How short the barrels are B). Pistols are meant for short
distance engagement…not a sniper platform C). Higher tolerance
results in more frequent jams (HAVE to use high quality bb’s),
and a little dirt or grime will result in a jam. Something you
DO NOT want in a skirmish condition.

for the accessories.

rail mount (and of course the optics that you mount on top :P)
-laser or flashlight (Yah know..m3’s, G&P Lasers etc.)
-Hogue grip
-fiber optic sights
-real steel Glock sights (I have a real deal adjustable rear sight
on my Glock 19…going to get a real deal front sight too very soon)
-real deal extended mag catch (can go under the more preliminary
upgrade…if you do decide to get a real mag catch instead of metal
-real deal extended slide catch (some dremling and filing required)
-real deal butt plate (makes the gun look more “authentic”)
-Glock plug (designed for the real Glocks, it plugs the hole at
the back of the grip…if I recall correctly it’ll require some
modification for it to fit properly)
-the “RIS mount” as found on the G23F.

the KSC G34 comes with an adjustable rear sight, extended slide
catch, and extended mag catch. If you don’t want to fit real
deal parts on your Glock 19, you can always try procuring these

think that basically covers it up for non-custom upgrades. :)

For the KSC Glock 17/18C and 34. The loading ramp (part no.10)
is plastic (as opposed to the metal OEM loading ramp in the
G19 and above models). My advice is to get this part along with
the metal slide + metal outer barrel.

recoil spring guide is also plastic (…the G19 has a metal
one…), so if you want increased durability you can A). Get
ONLY the spring guide. OR B). Get an enhanced recoil spring
that comes with a metal spring guide (more common than only
getting a spring guide it seems)
