Re: WTB: Commercial mauser trigger with side safety
Both Timney and Bold make adjustable triggers w/ side safety to fit the Mausers. Last I checked, Midway and Brownell's had the Timneys, and Boyd's Stocks carries the Bolds. I've used both on Mauser builds, and don't really see any big advantage to the Timney for the extra $$.
Good luck with your build!
