Re: TRG 42 bolt knob
I actually love the stock bakelite/plastic knob on my TRG-22. It doesn't look as nice as El Gordo's (which is a very cool design)... but I can cycle it very comfortably, there is no knurling to hang up and it won't snag on gloves. You can put a solid grip on it and it just slides in the fingers.
I think Sako did put a lot of thought into that knob and weight isn't the only plus... it's smoothness. That polished factory knob is the best 'feeling' bolt I've ever worked.
What's the saying: "Fast is slow, slow is smooth, smooth is fast?" I think the TRG smooth bolt knob was designed with that saying in mind.
That said... I still 'covet' El Greco's bolt knob design. That just looks great.
Cheers,
