Slick little slide - ShaloTek IC Sentinel RMSC Pistol Slide

I have never owned a compensated pistol or a fancy slick little slide like the Sentinel. However, I can say it definitely improved groups. I have a holosun 407k x2 on a custom steyr and this slide makes it shoot almost as well. The steyr has a lower bore axis, less mass and a better grip angle than a p320. I was about to toss my p320 until I was convinced to upgrade it. Between this slide, some trigger work and the Icarus Precision Socom module...it is a new favorite. I have only 2 complaints, the first being that I wanted the EDC but it wasn't available, that's my fault for not having patience. The second is the optic cut could use improvement. It definitely works, however, you'd be wise to add some green loctite (the kind used to lock in bearing races) to the slide if you don't want your sight to wander after a few hundred +p rounds. The screws stayed tight but the 407k on this slide pivoted sideways after a few hundred +p. I will end with this, I have fired 200rds of federal 115gr 9mm...standard stuff and it cycled flawlessly. So it can definitely work with standard 9mm ammo, don't let that deter you from getting it.
