Hey nine i just bought the same gun 3 weeks ago ( identical )
First thing i did that u should do is take out the magazine pin so it can hold
4 + 1
the next thing i did to mine was put on a ecotech hologram sight and a
" meat grinder " style muzzle break
with the holo sight its way accurate with slugs and with the muzzle break it looks bad a$$ and reduces muzzle rize by atleast 30%
