I have handled them several times and have seen about every test done on the internet on the new 2.0 compact which is about identical to the Glock 19 in size. Ergo's are better IMO and I believe it will be every bit as reliable from tests that have been done on it. The 2.0 trigger is much improved over the 1.0 but the very best is to put the new Apex flat Trigger called the Flatty in it. There are night sights available for it with more on the way. The full size model is only 1/4" longer in the barrel and the grip is a little longer as well. Handle both of them and see which one feels better in your hand since the difference in size is minimal.
