It eats WWB JHPs, PDX1s and Hornady ammo just fine.
The Skeeves on the Remington seem to be a little sharper than the other brands. All it did was make it a little harder to load in the mag but it fed and fired them just fine. I just avoid it in that gun now for that reason.
I have become very fond of Comp-Tac holsters. I would recomend picking one up for your P220.
Other than that mine has gone well over 1.5k rnds with not even the first hint of a hiccup.
Happy shooting, you will love it!
Oh and PS. That tube of grease that comes with it, you may want to look into picking up some of that stuff. It really does work wonders.
Recommend the Comp-Tac holsters. Still have one for a Sig 229. Great holster. Their dual mag carriers in Kydex are excellent. Both of the individual carriers are tension adjustable.
You may have to hunt around to find the appropriate .45 load that works the best in the pistol. That's the fun of having it.
It gets worse. After you shoot your Sig YOU won't be talking to your Colt. Have both. Haven't shot the Colt in years. Very nice pistols. Mine needed nothing.
My 220s have never exhibited any issues regarding ammo choice. I usually use Winchester (white box for range, Ranger or PDX-1 for carry), but I've also used Remington, S&B, and Herter at the range when the local Meijer is out of Winchester.
