I absolutely love the P210, p226 and the 232sl. My p225 (single stack 9mm) is also very nice, notable for it's very comfortable grip, not sure why i don't shoot it all that often. Might have to get it out of the safe.
All but the p225 have been further optimized by Bruce Gray (grayguns.com) such that their actions are absolutely wonderful. I wish i had Bruce Gray work on the 225, unfortunately i had the trigger job done by another well established smith and while it is perfectly fine, it pales in comparison to the Grayguns triggers. The 232sl is really sleek and pretty. A bit snappy as a 380 but surprisingly accurate and returns to a natural point of aim very quickly.
All are wonderfully accurate and reliable.
The p210 is pretty cool, shoots great, looks really pretty to my eye and the grip and overall feel is near perfect. Trigger action is kind of neat, it pivots at the top rather than pulling straight back like a 1911. The break is lovely but i think Bruce may have helped that as well.
Thought i'd love the A2 grips on the p226, they felt great at first but i found i shot the p226 better with the standard grips...I guess that's the thing about grips, the fit is as i should have expected, very individual. Ultimately the proof is in the pudding.
Congratulations by the way. Lovely collections. Wish we could get some of these models here in Ca. It's quite disappointing. Thankfully there are lots of p226s and p220s available.
I have a friend who has a first generation Mastershop X6 and its glorious. His has an aluminum frame and steel slide. Grip is a little generous (kind of reminds me of a 2011) but shoots so accurately with awesome sights.
