hey guys, long time no see. i used to mod on czshooters.com back in the day. now i'm looking for help with my Kadet kit
my Kadet rests in a 75B-SA .40s&w frame that was fine tuned by Matt Mink. The Kadet itsself has been modded by one of my favorite local gunsmiths to support a Gemtech Outback-II suppressor. I've had it for approximately 5-6 years and have fired thousands of rounds from it using all sorts of qualities of ammunition. it's been pretty reliable, even with cheapo stuff, until recently...
my Kadet recently started failing to fire. i'll shoot the first round from the magazine, then I find I have to re-cock the hammer and strike multiple times before the next rounds finally go off, sometimes not at all. I've removed the firing pin and spring and both appear normal to the naked eye. i was thinking maybe the spring has weakened from usage? initially i thought it was the firing pin channel clogged with years of gunk, but i cleared it out thoroughly and i'm still having problems with the gun firing reliably.
i didn't think it was the hammer spring because the 75 B-SA was originally meant to set off a 40cal round. figured it had more than enough strength to do the 22lr.
any advise would be great! want to get my gun back out on the range asap. it always draws attention when people hear (or dont hear!) my suppressor whisking rounds downrange.
