There is a write up about the Sigpro on the Gunnery Network. I think the Web site is www.gunnery.net if that doesn't work, try a search.
I have owned both and I really like both of them (Glock 31/2340). They are both great pistols but I think that the Glock is a little easier to maintain. There are more aftermarket accessories for the Glock. Even though they are expensive, hi cap mags are still available for the Glock
I have the SP2340 in 357 Sig and a Glock 20 (10mm). I prefer the Glock's sites (because of my lousy eyes ) and its trigger pull. The ergonomics of the SP2340 are OK but again I prefer the finger grooves on the Glock. Everyone says that a full size Glock requires large hands to be comfortable but I have small hands and don't have any problems with it at all. The first time I fired the G20 I was getting excellent groups in the 9 and 10 ring at 25 feet. I can't say the same for the SP2340 which was shooting low and to the left with CCI Blazer 125Gr TMJ. I did better with 124Gr FMJ factory reloads but still did not match the G20. I would like to try a G31 or G32 to see how it compares to the SP2340 but the .357 Sig round is not that popular in my area and the indoor range/gun shop I practice at won't even stock one much less rent one.
