No comp. The P220 is a classic and the P245 is a failed attempt right up there with the SigPro series. Most gun makers makes oooppsss guns - look at Glock's 36. GT has tons of mixed reviews.
The P245 is like shooting a brick. Try some hard hitting 185 grain +P Golden Sabres and you'll buy a P220!
The P220 is a dream. The P220/P226 are my fav sized Sigs.
The P245 just really never caught on but then again why?
Sig chops the crap out of a P220 and wants bucks for it.
Four years, 15 gun shops and ranges, weekly shooting, seen a hundred P220s and only one P245. Speaks volumes.
P220 - no doubt.
