Thank you for taking the time to answer my question. Consensus related to self defense calibers, what was I thinking! LOL
From what you are saying I may just go with a 357 Sig (my first choice). I was interested in loading the 40 S&W with 135 grain Nosler JHP in an attempt to duplicate the Double Tap load, but as the 135 grain projectile did not even get a mention perhaps I better stick with my first choice!
The 357 Sig was my first choice, but cheaper component prices, along with availability and a slightly less involved reloading process had me looking at the 40 S&W. I certainly am not interested in a 180 grain load, but I might be able to convince myself to go with the 155.
Thank you again for your time!
