I ran into a few issues with my brand new rhino and was able to fix them. Im hoping this write up will help someone else if they are having similar issues.
****I am NOT a professional gunsmith, Im an auto mechanic, that being said i have improved every trigger on every firearm i have owned with just a little bit of work and having attention to detail. I have even repaired dangerous attempts at trigger work that came on my brothers semi auto shotgun ***NEGATIVE SEAR ENGAGEMENT IS VERY BAD*** it liked to sometimes go off when dropping the bolt.
I picked up a Rhino a few weeks ago. It came with the DA sear kit so as soon as i test fired it i went home and installed the kit. After loading up with snap caps i was surprised that it didnt function. In DA the sear would not release and in SA the DA sear was catching the hammer and decocking the hammer. I pulled it back apart and and ran through the actions with the main spring disconnected and found the DA sear was too long and wasnt releasing. Simple fix, i got out my fine files and hones and polished the sear back so it would release.
While enjoying my victory over the DA sear i noticed the SA sear only operated by flexing the sear which looked like an accidental discharge waiting to happen.
Here is how the trigger works(see pic 1) the pin(blue dot) interacts with the lower sear tab(blue circle) and the sear moves up and lets the hammer fall. On my pistol the sear was blocked from dropping down to block the hammer by the upper tab being too tall(blue circle pic 2) which fully compressed the sear spring allowing for no visible movement. I polished back the upper sear tab(blue circle pic 2) to allow the sear to drop deeper onto the hammer surface. I did not want to mess with the sear faces(blue circle pic 3) because they are usually surface hardened and i didnt want to mess it up. I have at least quadrupled the sear face contact making me fell a lot better knowing the sear is physically in the way of the hammer now. I can actually see the sear move un and down when squeezing the trigger. There is still no noticeable trigger creep leaving the amazingly light and crisp break in SA.
