The 10mm has been my mainstay since 1990, this started with the S&W1006...I still shoot it and use it at times to remain proficent with it and and all of them in the 10xx series. Why is because I like to maintain the workings for each.
However I mostly carry and train the most with the Glock 29, double stack 10+1, smaller package, still reliable but if it is stolen, lost are have to be given up should I need it to defend myself or family, it won't be one of my S&W 3rd gen's!
At the present I'm reviewing some of the smaller 9mm options.
