I've been wanting to get one in .40 cal and have read way too much on them. They seem to be pretty decent with most complaints being the poor front sight. I really wish Blueforce would make their metal sights again. I decided to build a 9mm AR15 SBR upper because it would be compact and I already have a registered lower. 9mm AR15s are much more expensive though. Mines going to be more than my Colt upper was if you add in the price for mag block. I still intend to get a Sub 2000 though since I have thousands of .40 around.
We do not rise to the level of our expectations. We fall to the level of our training.
