[Kos-Mos]

1) Make and Model
KJW KP-05 Hi Capa

2) Purchase Date
July 09

3) Cost
$250 (surplus IG)

4) New/Used
New

5) Mechanical Problems
-BBU failure. The left side guide bent inwards and broke the nozzle, rocket valve and bent the rocket valve spring. (Waiting for new parts from Illusion next week).
-Frame screw treads stripped. The left side screw holding the grip in place stripped the hole in the frame. The treads are still somewhat present, but not enough to support the pressure from the hammer spring. Fix: I have re-treaded in standard size the hole and used a stainless screw from an RC car. Also modified the other side that showed some signs of fatigue.
-Upgraded recoil springs are not compatible with this pistol. You will need to change the spring guide bushing (you can use a TM stock unit or after market one), because upgraded springs are a tad bit larger in diameter and do not fit properly in the hole.
-Safety spring/pin is too hard to place the gun in safety. I filled the safety selector to make the notch smoother and changed the spring for a lighter spring (softer).
-Stock magazine fill valve stopped holding gas after about 10 fills. Changed for a new valve and all good now.

6) Aesthetic Problems
None

7)Round fired between failures
-5000

8) Changes to Internals or Externals
-Hammer spring (Guarder 150%)
-Polished the slide and frame. The slide is still the same as when I did it. The frame oxidized and is now a dull grey.
-Modified the hammer to remove de-cocking position.
-Painted the clear grip with Krylon FB. The pain is still holding VERY well. It is almost impossible to tell that the grip was not black to start with.
-Filed the hammer and BBU to prevent the hammer from grabbing the rear of the unit and block the slide from returning to battery (preventive mod)

9) Resale Date And Value
None yet.

Personal notes:
All in all, a good alternative to a TM pistol, with the metal slide and TK grip. Tolerances between the parts is not that great, but about as good as a TM pistol.
TM 4.3 magasines will not lock the slide when empty. I don't know if the mags I got (used) have been modified for that purpose, but the stock KJW mag does catch properly.
