no big deal
I own 3 686s with the internal lock. Do I use them? No. Do I mind the little whole in the frame? no. Will I not buy another Smith & Wesson? Yes. Just because a gun has a lock does not mean it will fail just at the exact moment you need it, hell any gun could fail at the exact moment you need it. No tool is 100% fool proof and not break. The internal lock just does not matter one way or the other. I have shoot hot load through mine rapid fire and all I got was a sore hand and shoulder.
Finch, I don't like guns. Reese, Me either but if someone has to have guns I'd rather it be me. (Person of Interest).
