I just shot the Kamloops F-Class match this past weekend, and there are predominately single stage triggers in most of the top end guys rigs. A few of us run 2-stages, and the BixnAndy 2-stage is amazing. I don’t feel I give anything up running a 2-stage, with almost all the top end trigger makers nowadays, it’s more personal preference then one make is better then others. I’ve used Jewels and Triggertechs the last couple years as well, and they were very good too. All good choices.
(P.S. Kamloops match this weekend was a fantastic experience, extremely well run and super friendly group who run it, would recommend anyone, from beginner to pro, to come to a shoot there). We drove 9 hours from Edmonton and was definitely worth our time. Will be back for Westerns and year end match there too. Same goes for the Calgary F Class matches. No excuse to not come and try it. You’ll be hooked after one match though, be warned!
