Well, I thought it was time for an update, having owned this for almost half a year. Basically, see how much has changed. Included are photos, which are needed to illustrate some of my points.
Firstly, this has become my primary sidearm (out of my other 3), it's without a doubt the most reliable. As such, since Feb/March, it's seen use in 9 full days airsoft (as a sidearm), and about 2 days of general plinking and mucking around and finally 1 day of use as a primary weapon (pistol training). All in all, it's had roughly 500 rounds through it (as I only use 0.2g for pistols, and I know how many rounds each Co2 cartridge gives, it's easy to calculate that number)
Ok, onto the re-review.
Externally:
The paint flakes off easily. Now, this is both bad and good. For those of you who enjoy battle-worn gear, good. In almost no time you'll have chipped paint, scratches, the works. Your X-Five will look like it's been to hell and back! For those of you (like me) who want to customise the colour-scheme/have polished metal, again, this is good - it makes your job a lot easier.
The bad - not everyone wants this. Seriously, the mere action of holstering/drawing your X-Five can result in paint-loss. The area around the trigger and mag-release loses paint incredibly easy (see photos).
The paint isn't much of a problem for me but 'collectors' (or people who wish to re-sell) may wish to take this into account.
And now, for a problem I've never encountered before. The metal is actually pretty weak, at least it is on the slide. I've actually managed to get a nice visible dent into the top of the slide. The metal is pretty soft - so be careful with how you handle it. None of my KJWs have ever had this, really confused me.
Internally:
Initially (see P1), I wasn't terribly fond of the X-Five. The takedown and re-build was when I first got the pistol, a little tricky. However, over time (having taken it apart and rebuilt it for cleaning) does become easier. However - my point remains, the recoil-spring and guide-rod design is (when compared to KJW's SIG-Sauers) quite frankly, crap. The only thing that holds the recoil rod in place in the slide is the spring - no pegs or slots. This means you have to be very careful when putting the slide back on the frame - it's a lose fit, and you have to carefully balance the slide to stop the recoil-rod from slipping out of place.
That's more of an annoyance than serious issue. Which leads me to this -
There are 3 small screw which hold the gas-piston thing into the slide. 1 at the front, 2 at the back. I've lost one of them. One of the rear screws was ripped in half, and fell out. Anyone else have this? It may be sensible to thread-lock the screws. Or, I could have received the 1 and only dodgy screw. It still works though, but I will be taking it to a mech to see if they have any spare screws.
Clearing the chamber. This is a fairly simple thing on all GBBs. Remove mag, pull slide, round falls out of chamber - congrats, you got a safe gun. Not on the X-Five. For some reason, no-matter how many times you rack the slide, any rounds in the barrel will not come out. This isn't just mine, Dave at Patrol Base confirmed he had seen this issue as well. The solution? 1) - put the mag back in and fire off every round until only Co2 is left, 2) remove magazine, find a long thin object and manually push the round out or 3) - take the gun apart and clear the barrel.
Performance
Without a doubt, the most reliable GBB I own. To put it into context - a fully gassed up KJW P229 magazine at 19 degrees C, can shoot off about 1 and a half magazines worth (26-28 rounds). The X-Five, in 19 deg.C can fire upto 55 shots per cartridge. I've left a Co2 cartridge in an X-Five mag for 2 months, come back and found it working perfectly. FPS drops over the usage of a cartridge.
FPS - this is quite odd. It varies depending which magazine I use. I have 2 magazines which refuse to fire over 320 FPS. However, my third mag starts shooting at 380 FPS, but then gradually drops down to a more reasonable 290.
FPS drops over time. ALWAYS CHRONO! Also, make sure your game site allows Co2 pistols, as some do not.
General comments
I'm not really a fan of the safety and trigger system - I'm more used to SIG style double-action (DA) triggers and de-cockers than the X-Five's thumb-rest safety and single-action (SA) trigger. This however is personal preference, 1911-users will probably like it.
The safety - it's supposed to be ambidextrous, but I can only work it with my right-thumb. Not sure if that's a user or gun error there. Again, I'm more used to DA-de-cockers and prefer them, but it's not a problem.
The iron-sights on the slide are... acceptable. The rear-sights are missing the "dots" one uses to aim (the front has one). This can make target acquisition diffficult in low-light areas.
So, to recap. ( TL;DR )
Almost half a year later and after a lot of abuse, my X-Five is still running strong. It's incredibly reliable, it's incredibly cost-effective to run (£0.50 for a Co2 cartridge, which can pump out a lot of rounds).
There are some design and manufacture issues - the recoil-spring and guide-rod design is awful, the paint flakes off like a someone with a serious dandruff problem, and it's possible to dent the slide - but on the whole, those are only minor issues.
It fires and cycles beautifully, ergonomically it's a delight (imagine if a P226 and a 1911 had a love-child). It requires very little maintenance and cleaning.
Look after it, and it'll work. It's going to take an awful lot to prize this out of my hands and get me using something else.
