Hi Mas, My ccw is a g23 and now and then g27. Figure 40 is a good all around round. If you were to recommend a slightly better rd for certain conditions such as climate due to heavier clothing, or maybe conditions lm not thinking of, would you go with 10mm or .357sig? I ask about those two because I can get (I believe anyway) those caliber barrels for my current pistols. I know you prefer .45 for cold climates and I do have a Sig 220 but it seldom goes with me. Probably go with Lone Wolf barrel because it will be easy to distinguish from the black glock barrel. Thanks for your input. Your recommendations are highly regarded!
