Posting this under competition as this seems the most likely place to find users of comps and ports. I'm going to start converting a long slide .40 to .357 Sig and want to either Magnaport, install a Carver Comp, or both. My research and understanding of such things suggests the .357 would be great for this since it's pushing a light bullet with high pressure. But since I have no experience with porting or comps I'm hoping you guys can lend your opinion. This gun is going to be for fun and my definition of a 'blaster'. 15 rounds of .357 Sig with low recoil and a Trijicon RMR sounds like a lot of fun to me! I'm already aware of the FPS change and increased noise, this is something I'm going to do and just want to get the most effective setup. What would you recommend? Porting? Comping? A combination of the two?
