In terms of ammo cost for a larger round, again i'm all ears to suggestions, what would be the best bang for the buck in terms of defense/accuracy/price?
I heard that the mosquito has a problem, that is peaky with cheap ammo, to obtain reliability feed them with the best ammo, otherwise is prone to FTE and FTF... I had shot the S&W 22A, the Ruger MKIII and the Browning Buckmark... all 3 are good choices but as personal taste I do preffer the Buckmark, the Ruger is good too, but is some pain to disarm and clean.
About your second caliber, I still suggest that buy the 9mm.... because 9mm is cheap to practice but with decent stoping power for self defense, 9mm it's not only cheaper, it's also easier to find (more popular) than .40S&W... If budget is in your mind, stay with the 9mm.
