I really like my rock island, it's the same model
@cohunt posted about. It's been 100% reliable, is super accurate, and the configuration really helps keep the felt recoil down.
Say whatever you want about a double stack not being a true 1911,but in a caliber that has some recoil speed I'll take a double stack iver a single any day... The wider back strap spreads out the force and makes it much more comfortable to do a lot of practice with, and the grip shape and size fits my (glove size L) hands really well.
I had a single stack kimber 10mm for a while... Never could get it to feed reliably.. Tried different mags, sent it back to them twice... It was a nice gun when it worked, but my ria out shoots it pretty easily, cycles everything I've put through it, and feels better too. Only 6hing the kimber has that RIA doesn't is the name
