the thing is, after i replace the nozzle with a new one (the one above), it still wont chamber BB correctly AND it breaks and have the exact same hole just after 1 magz of tries.
what have caused this? i use guarder power up gas which shoots kinda hard but i think its just straight up propane. i dont think it is caused by the pressure being to hard.
this also happens with my first nozzle AFTER i tried using long hi cap (50bb) magz. i dont know whether this is a coincidence or not, but my friend's hi capa with SD nozzle also cannot

Well, if you have that hole formed on the side, then you'll lose pressure, and of course the slide will cycle weakly. If it doesn't cycle with enough power, then the slide won't be able to travel back far enough to chamber the next round. The piece that use to cover that hole is also responsible for guiding the nozzle, so without that part there, the nozzle would no longer be guided properly, which further explains why the nozzle is moving out of place and riding over the following round. All of the problems would stem from that missing piece and the resulting hole.
As for how that hole formed... beats me. Any number of things could have caused that. See how it contacts the blowback unit when you install it, and look for anything strange or out of place in the action that might cause that type of damage.
Because a new nozzle is also having this problem, I would also look at the blowback unit to see if there's any damage to it, and check fitment with your slide to see how it interacts. What brand slide and blowback unit are you using? What piston head are you using?

I just noticed though they have 2 kinds of SV hammer listed on the site:
AR1324(one I ordered): http://www.prog4.com/db/product-show.asp?refno=AR1324
AR1608: http://www.prog4.com/db/product-show.asp?refno=AR1608
Note the latter is labeled for TM 1911, and uses a 1911 sear. I think they may have sent the latter in error. But This will be the first instance that there is a difference between the hammer...as I've used the 1911/Hi-Capa hammer interchangeably.... |
They are the exact same hammer. The only difference between the two kits, is the sear. Technically, that hammer is actually only for Hi-Capa anyways, as installing the half-cock nub will not allow it to function properly in a 1911. The location of the hole is different between the two systems.
