Probably more than a little accurate. They were both manufactured initially somewhat concurrently; I suspect that SIGARMS was trying to cover their LEO bases by having both a metal- and polymer-framed DA/SA, and the Sigpro (at that time in both 2340 {/40 and .357 SIG} and 2009 (9mm} incarnations) was less expensive and came with 2 different backstraps to provide for greater individual fit potential.
The Sigpro, be it in either earlier or current P2022 configuration is an interesting, and high-quality gun. SIG never really marketed it aggressively or effectively, so they tended to fly under the radar. Unless I develop some sort of a compelling need for a DA/SA in .40 (as I have the 9mm DA/SA niche pretty effectively covered), it's unlikely one will migrate into my vault in the near future, though.
More than a few years back I seem to recall gunwriter Peter Jordan penning a well-written article comparing the Sigpro against the P229, and in his opinion the Sigpro came out ahead.
The Sigpro does combine characteristics of the metal-frame classic P-Series and P210 captured barrel movement nicely. OEM magazines have always been MecGars, which is nice. Before morphing into the P2022, there was a subtle ergonomic modification performed on either the decocking lever or the slide release, I forget which (and the original set-up wasn't bad, either).
In my opinion, they might be even better served in today's market by offering 3 sizes of replaceable backstrap, instead of the 1-2 currently offered.
Best, Jon
