I know everyone loves Jewell triggers. I personally have had only one, on a Surgeon 7STW. I only shot factory ammo and never had any ammo problems. After 60 or so rounds the trigger died. I called Jewell. Guy who answered only spoke Spanish. I speak Spanish but wanted a second guy who spoke English in case conversation got complicated. I returned it to Jewell for repair. It had broken a lever inside. I waited a long time for return and finally called again. They had lost the trigger in the shop, finally found it, and were now going to work on it. A week or two later they called back for $75 payment for repair. They said the only way the lever could have broken was if I had blown a case, and the back pressure had broken the trigger lever, and it would cost me. No such thing had happened. Obviously no warranty for a faulty product. True story and I swear to it. I love Triggertech. Also very good experience with Timney and Shilen.
