my brother had it before me (he coulf f&% up a wet dream) he gave it to me saying that it wasn't fireing right. i think that he cut some out of the front spring the ends ar mared up and same on the rear spring. Hens weekening the spring and then bend and snap. this aint the first firearm that he mest up. he fubar'd a cetme that i now have, TLC and $200 and shes good as new. I like the s-20 so I want to fix it.
