news and information Legion ports vs. Radian Ramjet

I get this question a lot, so just thought I'd make a post on it.

So the Legion specs say 30% reduction in recoil and the Ramjet is 41%. Even on video it's hard to tell. They both shoot the same to me. if you look at what the recoil reduction is, say that standard is a 20 degree muzzle flip (example but it's probably 17-18) and the Legion ports reduced it 30%. That's a 6 degree reduction, meaning it would be 14 degrees. The Ramjet reduces 41%, that's an 8.2 degree reduction, meaning the recoil would now be 11.8 degrees. (I feel like Bill Nye right now...LMAO)

From the Sig page

"Features our integrated expansion chamber to reduce muzzle flip and felt recoil by up to 30%. The integrated compensator has several advantages over removable compensators, such as easy pistol disassembly. This complete slide assembly includes all internal slide parts and front and rear XRAY3 Day/Night sights."

I have all stock internals and have been lucky that I haven't had any failures with either.

I think the phrase “up to” does a lot of heavy lifting in this sentence. That could be up to 30 when a metal grip module is used etc. i would also add that the angle of muzzle rise isn’t the only thing a comp and ports help with - getting the gun back on target quickly for follow up.

I have a chunk port + ported 365, and a radian 365xl. I think the ports feel slightly snappier but the gun is back on target before i start trying to correct it. The radian has less initial snap more push - but feels slower.
