I have a few USH’s: two in 12 ga and one in 20. My favorite 12 ga USH is one I bought off of here a few years ago. The trigger had some work, breaking around 2.5 lbs.
I recently went to film a video shooting the Twister slugs for my YOUTUBE channel and 4/5 shots had light primer strikes.
Then, last week, my son and I went hunting. We had a old mature doe show up. He cocked the hammer back, squeezed the trigger and nothing. It happened again. Needless to say she spooked off, but not before I instinctively drew my .500 SW and put one through her lungs.
When I got home, I compared the firing pin with my other one which I bought “new, old stock” and only has about 10 rounds through the it.
The firing pin is considerably shorter than the one in my new USH. Then I read about firing pin erosion in these guns due to some primers, especially the euro stuff. I personally got well over 1,000 slugs down the barrel since I’ve had it, with 90% of those being primed Fiocchi or Cheddite hulls.
I ordered a firing pin and new firing pin spring. My question is, how hard is it to replace the firing pin? Not a lot of info out there.
Any info y’all could give will get greatly appreciated. I’ve replaced trigger springs in every pump I own and did a trigger job on my Super Red Hawk. Hoping is along the same lines.
