LIKES:
I've been shooting my P220 in competition since early August without cleaning it. No hiccups.
Nice accuracy--more than I can reliably use, in fact.
The only time I've ever had an issue that stopped the gun was when a trigger return spring broke.
SIG/Sauer will supposedly sell you a "Gun Pack" of the most commonly-broken parts so you can keep 'em on hand. I haven't gotten one yet.
Mine was cheap; it was made in "West Germany" in 1989 and I assume it was a police trade-in at some point.
I like the trigger OK. But then, I didn't learn on a 1911 with short travel; maybe if I had . . . . honestly, I don't even notice the transition in competition, and I figure if ever have to shoot for blood the tension will be even higher. I just see the sights and press the trigger, and the shots hit. Or I rush, or I don't see the picture, and I miss.
DISLIKES:
The P-Series has a pathological, co-dependent love affair with rust. I finally Dura-Coated mine. We'll see how that holds up.
Only one of my (factory) magazines drops free. I have to yank the others out.
I didn't like the grips either, so I replaced them, first with Hogue rubber and now with walnut.
The aforementioned high bore axis, which is certainly no worse than you average hair dryer.
I'm starting to think mine doesn't fit my hand all that well since handling the single-stack 1911 clone ParaUSA had me using at Blackwater. It's beginning to seem to me that I've been shifting my hand around to the point that my wrist was breaking a little. Whether that's a matter of fit or simply something I need to continue to train out of remains to be seen.
