I tried the striker-fired guns but they didn't have the heft I was comfortable holding. The S&W Gen3 models in 9mm and .40 caliber felt best and I started working my way through different models and variants. I had to buy them online because none were available locally.
I settled on the double-action-only S&W model 3953 and 4053 as carrying options because the Gen3s are reliable and accurate, fit my hand, concealed IWB well, and I could rely on my past practice skills in a critical life-threatening moment.
