ACR - This is a hard one for me because I thought the rifle was amazing, ergonomics were really well thought out. A bit heavy but hey pistons are known to be so. But little aftermarket support and Bushmaster never producing caliber conversions really killed it for me. If they did rally behind the platform I'd probably buy it again. But after reading up on the ACR forum the ACR has become the neglected, bastard love child who is forced to live under the stairs. The SCAR has taken the limelight and really after shooting both I thought the ACR was a better fit for me at a more affordable price point. SO looks like I might go SCAR 16 when I win the lottery in Hawaii.
Sig 2022 or any Sig pistol that is not a 1911. This is nothing to do with craftsmanship because sig is one of the top companies in the firearms industry. It's totally operator error, I cannot for the life of me not actuate the slide lock, causing the slide to go home on the last round. I've tried every sort of safe manipulation to get my thumb away from the slide lock.
Beretta Px4 (40). First firearm I bought in Hawaii during the Newtown incident. I bought it because the LGS in the area were either sold out or marked up to a ridiculous price. I do like the platform but the 40 was too snappy for me which is why I won't get a G23. I'd probably buy the 9mm version for sure. Shot my buddies and it felt good and I did decent with it.
other than those sensitive points I've been pretty overall happy with my firearms I've purchased over the years.
Cheers,
