Went again with another bud that just bought a XDs .45 and he wanted to shoot mine to compare. I like the idea of the smaller .45 but it's just not for me. We swapped 4 different guns for about an hour total time, maybe went through 450-500+ rounds between us both. I know that we went through 200+ on my XDm, had some hydra-shok ammo I wanted to test, along with another 150+ rounds of my normal Federal stuff. Not sure how many rounds of .22 we went through, at least 100+ by my guess. His stuff, I think he picked up 50 rounds each of the .45 and for his .380 plus what he already had on hand, maybe another 60-70 rounds combined.
Both of us shot essentially the same, good with the SR-22, ok with the .380 ( I don't even know what make/model it was) and about the same with the XDs. He was impressed that the .40 shot much tighter groups, even single handed, either right or left. As we were walking out, he asked if I wanted to trade my XDm for his XDs. I just had to laugh a little, told him no way.
Man I do love my XDm, even more now.
