Yeah, The Walther is for me... Glad nobody is shying me away here..
The Sig Mosquito would purely be for the wife and to help her acclimate to firearms. Right now she's only get a Ruger 10/22 that she hasn't even shot yet (the joys of Christmas presents, a wife that hates cold weather, and a solid Wisconsin winter).
My shop normally carries CCI ammo... and I have a thing of it somewhere. I shoot cheap Skorpion ammo from the 10/22, but if I know the Mosquito is finicky, no issue getting the right ammo for it once some comes in.... no bid deal.
