So I just picked up a block 20 to carry while hunting this year. I took it out and put 200 rounds of American eagle 180 gr fmj and I was blown away by its accuracy.I am used yo shooting flocks and up until the 20, my 34 was the best having almost a 5.5 barrel. Both me andmy shooting buddy shot the 20 better than any of our pistols in fact. 3-4" groups at 15 yds! Is there a reason the 10 mm seems to be so accurate? This is my first experience and I'm very impressed.
