I know many folks go for the ultra lightweight carry pieces but - I may be an exception. I actually choose weight!!
I also know many members here are full size 1911 carriers and so maybe they too have no prob with weight either.
I have shot with several of the lightweights and frankly - I hate em!! Even with 38 spl in a 642 - it feels ''odd'' to say least, as well as being punishing. My SP-101 was as light as I want go in a snub and for semi's well - if I wasn't carrying the SIG ST 226, I'd still be choosing heavy - 1911, CZ-75, etc.
IMO - if you can conceal it - go large and heavy. Bottom line is I reckon you have not only a more robust piece but - an eminently more controllable one too.
I am so used to the weight of the SIG on my hip - and it presents no discomfort to speak off at all. It is however solid, recoil-damping and pretty accurate.
I'll take heavy over super light - any day.
