Just returned from my local indoor range after shooting $30 worth of 10mm (one box!)through my new P220 SAO Elite.
One thing is for sure....you certainly aren't shooting a 9MM! Recoil is pretty stout and snappy, but the pistol soaked it up and the excellent G10 grips give you an excellent purchase on the pistol. Given that you are shooting such a powerful round the P220 actually shot fairly softly once I became accustomed to it.
Accuracy wise I did fairly well. Took me a bit longer than usual to get the sights dialed in. Very nice sight picture, by the way! Shooting from a rest, head shots on a 'bad guy' target at about 20 yards was fairly easy, but not as tight as with my P226RX SAO in 9mm. I think I have concluded that my PELT equipped P320s and SAO P226's, a Legion and the above mentioned RX have me spoiled. The trigger on the new P220 is pretty good, but a fair amount heavier than the others. I am sure it will smooth out with time, and I may also install a lighter mainspring, which I have done with the P226s, in the future.
Had three failures, but I believe they were all my fault. The first time the fresh round was trapped between the slide and barrel, the other two the empty ejected but the new round failed to feed. I am almost positive that upon recoil I dumped the mag
!! I had done that once before with my P226 Legion. Being conscious of my grip should take care of that in the future. One other observation: this thing slings brass!! There was a small area with several empties to my left and about 18 feet behind me where they bounced off the divider and hit a cabinet! Also, as I have seen in a few Youtube videos you can see where the empties are hitting the slide just above the extractor.
All in all I am happy with the new P220. Not sure I will ever shoot it as well as my SAO P226's but I am sure I can get proficient with it.
