Congratulations!
Neat little guns. I'm a fan of the 329s (4" was my all day every day carry gun for the better part of a decade - still my backup bow hunting elk).
I managed to pickup OPs twin a while back. Haven't shot it much. Did some chrono work and shot some 25 yd plates but never put it on paper. Slipped it in the back pocket of my carharts on a couple of walks - comfortable for an hour and a half or so (as long as I go any more).
Here are some chrono results - the 2 1/2" backpacker is a bit faster velocity wise vs. my 2 3/4" M69 (diff is really meaningless, but interesting).
