The thing is even though I tried a J-frame and hated it, I still want one, and I don't know why...
Is it stupid to want to buy a gun that I didn't enjoy shooting and shot terribly? If I did get a J-frame it would be for pocket carry, which is the only carry method that works for me with my clothes and South Florida weather.
Carried a Colt LWT Commander for years, but last summer, purchased an early run, S&W M640-1. Earlier this year, I acquired a NIB scandium alloy M&P340.
The Commander doesn't get out of the house much, anymore.
Wearing jeans, the M640-1 gets carried OWB, in an Andrews Custom Leather, tension hold, "Saddle Style". Really nice holster, that conceals - & presents, exceptionally well.
The M&P340 (worth every penny, BTW) has become my primary EDC. Pocket carry in a DeSantis Nemesis: baggy shorts, or Vertx lightweight tactical khakis - for normal business casual, is a piece of cake. It's easy to forget you're packing, no noticeable printing, & best of all, it's ALWAYS there. After years of dealing w/ a full size auto loader (left at home half the time), I'm REALLY loving the whole "drop it in my pocket, & go" thing.
Surprisingly, although J frames are a... "bit of a challenge" to fire accurately (had to re-learn my D/A technique), I have found that they point faster, & more naturally then any other handgun I own - bar none.
I have found that Hogue Centennial Tamer grips, make a world of ergonomic difference, for a gun that gets shot a lot, & carried OWB - like my M640-1. Although do-able for me, they add a bit too much bulk for dedicated pocket carry.
My M340 wears a Hogue Bantam. Not quite as ergonomic, but great for maximum concealment.
Best of luck w/ your decision!
