I rarely carry my 4 686 Plus, but do carry my 2.5 model. A new 2.5 barrel would cost $140, and I would have Dave Olhasso install it (price not known). Based on Lucky Gunners testing, the 2 and 4 revolvers give similar results in ballistic gel. I know thats not the ultimate test, but its something: https://www.luckygunner.com/labs/rev...llistics-test/ Any thoughts would be greatly appreciated.
