I bought a X-5 Competition in early Feb. 2014. Loved it! So, I purchased a X-6 L1 in April, 2014. Really, really loved its trigger.
I ordered a SIG p210 Legend Super Target shortly after getting the X-5. Spent a year waiting for delivery, was promised at least three firm delivery dates. They never shipped me one and finally admitted in late Jan. 2015; they had the export problem.
So, I immediately ordered a X-5 L1. It was delivered in Feb. 2015 with two black 10 round mags labelled
SIG SAUER P226 9mm. Those mags never worked in the L1. I found out the mags with the silver base plates were not available, anywhere. Finally, bought mags with black base plates that work perfectly. Unfortunately, I had gotten rid of the X-5 Competition before discovering the mag issue.
Actually, I could tell no difference in shooting the Competition and the L1. The adjustable triggers of the X-5 L1 and X-6 L1 are great allowing me to get really light trigger pull; and, the triggers are unbelievably smooth.
I've had good experience with SIG guns, both US made and German made models. However, their business practices are another story. Putting me off for a year on the p210 Legend was bad enough, but selling me the X-5 L1 with mags that won't work was too much for me.
