I ordered a few Superstruts for my new P226X Legion SAO and P226 Elite.
I installed both and was quite surprised to see that the Legion SAO is using what looks like a copy of the Superstrut. It certainly isn't as nice, it looks stamped compared to how nicely made the Superstrut is. Anybody else notice this?

I also noticed this back when the P226 XFIVE Classic and STAS were released by Newington. The real standout feature of Burke's design (that Newington's version copies) is that extra half-moon cut that provides clearance for the bolt of the safety lever on SAO P220-series.
