The Clark kit is a very well done kit, great support at the chamber, throated very good, and the comp is quite efficient. It took very little fitting to get it to drop in my Kimber and function proper for a 1911. It didn't fit my Ruger so well, so I keep it in my Kimber. It feeds flat meplat bullets like butter
My Kimber is outfitted with a Flat Firing Pin stop, 28 lb Mainspring, and 20 lb recoil spring. Mags have a +10% spring (Wilson 47D), but I'm only running Super-level pressure so slide velocity is not an issue, getting about 4-5 ft of ejection. I'm running a 275 grain Hunter's Supply at 1050 fps along with the Montana Bullet Works LFN GC (1100 fps), recoil is mild, so repeat shots are a pretty fast follow up. I run the speeds up anymore and time between shots gets longer, so I figure a compromise is in order.
