Dear Mark,
I solved issue flowing you instruction.
Thank you so much

.
I have several questions (I hope this could be interested for other forum members, too):
1. To buy spare part:
As I twice "grinding" the original sear, first time after ~3300 BBs, and second time (yesterday) after ~500 BBs, it could be concluded the material is to "soft" for the application.
I would like you opinion about the next options in order to have
longer period without the (similar) issues:
a) I could order spare part from:
https://www.kyairsoft.com/shop?search=%23X-43
but as it is original part from WE I am suspicions it is the same quality (soft) and the issues will repeat soon.
B) Second option is to order aftermarket CNC steel part (but for TM):
http://www.wiitech.com.hk/product-detail.shtml?product_id=356&path=17_128
Does it be fit for WE XDM?
c) Or it is better option: Full hammer assembly (as you propose):
https://www.kyairsoft.com/shop/product/we-xdm-complete-hammer-set-46840?search=We+xdm
2. How to maintenance / oil pistol:
How often and what lube to use?
How to clean pistol barrel?
My apology for the several questions but I would like to hear your opinion.
Best Regards,
P.
Hi mate glad my video helped you fix the gun.
No need to say sorry for the questions that's part of what the forum is here for and we are happy to help if we can..
As for the enhanced TM steel sear, apparently they are compatible BUT I have not tried one myself so I would NOT tell you to buy one, because I don't know first hand if they are compatible, without some fettling..
Personally for the price they cost and for how long they last, unless you want to risk it and see if the cnc tm version fits, I would just buy the original replacement part, they are cheap and last quite a long time, I'm not going to lie though, because I have a lot if guns and shoot all the shooting sports/hobbies some of my guns last longer as I don't put as many rounds through them..
Unless your willing to risk the TM CNC Steel part not fitting without modification, buy the standard WE part, I do not want yo recommend you something I have not tried myself..
As for maintenance and lube etc, everyone is different on this, but I will tell you what I do with that gun and a few of my others..
Unfortunately I had all these types on videos on my YouTube channel but I now have to upload everything again to dailymotion which is going yo take time, a month or two I'm sure.. But I'm sure I can talk you through it for now..
Clean the gun after every skirmish, that way the gun is clean and ready for next time, cleaning will not do harm, if your not skirmishing and using the gun in none dusty environments, do it every 500 rounds or so, there's no correct number of rounds, just do it when you think the gun needs it, a good sign it does is a dirty inner barrel or sticking nozzle or slow down in cycle speed..
Field strip the gun, clean the inner barrel, with a push through rod, and cleaning patch, either remove your inner barrel from your hop up unit, or turn your hop right down making sure the cleaning match does not contact the hop nub, or at least its not pressing hard on it which can damage it, as you know how to take your gun apart I recommend you fully remove the inner barrel from the hopup chamber/unit, and clean it that way, just get a airsoft push through cleaning rod, attach a cleaning patch, there are a few brands, I use Bisley, but you can even cut up a cotton t-shirt into cleaning patch if you want, although proper cleaning patches do a very slightly better job. Twist and push the cleaning rod and patch through the barrel your see when it's clean
Clean the loading nozzle from dust, and then put one drop of pure silicone oil, or synthetic oil such as light murder oil, or even pellgun oil on to the blowback unit loading nozzles piston head, one tiny drop will do, if your using green gas that's going yo be lunging your gun anyway. (some brands contain more oil/lube then others)
Then clean the slide rails and frame rail, remove old grease oil and dirt, For guns with metal frame rails and metal slides I personally use Abbey LT2 moly based gun grease, or tetra gun grease, but mainly Abbey LT2 gun grease, get a very small amount or your finger or stick etc and rub a tiny amount onto the frame rails, do not over grease it as too much grease is as bad as no grease, you just want to put on a very thin layer, just so it look shiny.
Do the same with the slide rail also..
If you want yo clean your internals also there's no harm in doing it, just do not over grease or oil them, in fact I would not even bother with grease or oil on the internals of that gun if your using green gas..
This is just what I would do mate. I will do a full maintenance video on this gun as well as all others I own if I've not done the video already in my collection, but like I say I'm on huge catch up, basically two years of work catch up, so it will be months before I can start doing new videos, but I'll push this video to the top of the list, So I Hope it helps in the meantime.
