Umarex M92-A1 reassembly issue

[Berettaowner]

So I just got this gun it worked fine out the box but I wanted to polish it so I completely disassembled it polished everything and put it back together I thought the right way but I believe the valve knocker is not hitting the valve on the magazine because it won't shoot or I may get one or 2 shots off after taking it all apart n putting it back together again and again but I'm at my wits end in I'd like to avoid buying a new gun I'll include pictures if anyone knows or owns this gun and try to find any discrepancies that would be very much appreciated

Why?

I thought it would help 

I can add more picks and deconstruct further but I'm fairly certain the problem is in the hammer assembly

Upon further inspection I believe I may have found the issue there's a small knick in the hammer probably from when I was polishing with the dremel and mothers mag and aluminum polish I'm going to try and hammer the raised edge back down n smooth it out maybe add some grease to the spring that holds the little arm that comes out of hammer because that was out of place when I took it apart this time and the hammer has a bit of a springy noise to it so the grease should help with that if it doesn't work ill be in the market for a working hammer assembly

I did what I could went a little over board with the punch and hammer but I did get it flattened down and gave the whole thing a good clean but there is still material missing I'm hoping that the raised edge and the dirt was the problem but if this doesn't work I may try to do some precision work with some metal filler and sand paper but on the other hand I may just end up buying an identical gun for spare parts and an extra mag we shall see

Well I give up all the functions seem to work but it's just not hitting the valve button on the magazine or not hitting it hard enough I'll be back when I get a new gun

Sorry can't help.  I have a WE version which is different. ?

They are very finicky.  The parts need to work perfectly together for it to cycle properly.

Absolutely I feel the same way definitely going to be more careful with the next one. There's a few more things I may try but I've definitely spent to much time on this to be considered a sane or reasonable person but I've never claimed to either so meh
