I like 9mm Hydrashocks in a sig but a 9x18 Makarov does nicely in a CZ-82 a lot like .40 cal- got one, a Springfield...it stays in the safe.. but I admit, I'm happy with a .45 and two extra mags
but if I have my .44 mag covered....that's when I'm happiest because I don't miss and I'm good to 200 yds no problemo and just one hit...and bad guys fall down, go boom. plus I'm fast with it....got enough muscle memory I just pull and shoot.
or did you mean like Insurance-insurance? wouldn't buy that..... always figured better to be judged by 12 than carried by 6 (or one if I get cremated)
