I wanted to post this in case it may help someone. I bought a used Gaucho .45 last year (a trade + $150 cash = $350) . It had the 'misfire' issue. Out of every 6 rounds, only 4-5 would fire. I did my research, & was preparing to send it to Taurus for them to repair, but I wanted to explore ALL my options. Fedex was going to cost me $69 to ship overnite (NC to Miami, FL), USPS wouldn't ship without a dealer, & I never made it to UPS, but I expect the price would be similar to Fedex. Dealers may have been able to ship it a little cheaper for me, so I wanted to find out ALL my options....especially since I've read varying results by owners who shipped theirs to Taurus. I went by a local gunshop/firing range (where I shoot) to discuss my situation (them shipping for me vs. possibly working on it). They had one of their gunsmiths check it out first. He fixed it for me. He told me that all he did was adjust/tighten the hammer spring. It cost me 1 hr. labor + 1 box ammo = $66 (about half ammo cost & half labor). He put one box of ammo thru it & I put another 40 rounds thru it with NO MISFIRES! I want to give props to 'On Target' Shooting Range & Gun Shop in Asheville, NC. They are great!!! I am very satisfied & happy with my decision. I really do like this gun a lot! Too bad Taurus didn't tweak their design, fix this issue, & continue to manufacter these bad boys.
