First impressions.....Wow! Why didn't get get an H&K sooner? I was very pleased with it and had 0 issues with the 150rds I put through. Recoil was verrrry minimal for a .40 caliber.
The only thing I need to work on his getting used to is all the trigger pull.
I used Remington 180grn UMC since those were much cheaper than WWB. Only difference I saw in that was increased muzzle flash and it made my gun extra dirty.
