Following some back issues, I now carry my LCR appendix style with no issues. In fact, I've come to prefer it. Use a kydex so don't perspire on it as badly. Suggestions for G19? When cooler weather rolls around I typically carry that.
I have (and use) a DeSantis INSIDE HEAT which is a thick, formed leather holster for a 19 or 26 and costs around $30. http://www.desantisholster.com/ In formed polymer (not a Kydex) is a BLADE TECH (can't remember the name) but also fits my 19 and 26 for around $35. Both are very good, inexpensive but perform at a higher level than their price would make you think. High quality.
Used a Fobus paddle-style for more than a decade with great ease for my G23(3).
Decided to add another holster when I picked up my G19(4), so I got an IMI Defense paddle-style. WOW. Closer to the torso, better paddle design and an all-one-piece design make it a real joy to wear everyday.
