I like using TiteGroup in my .40 S&W and in my 9mm.
I just did some test loads this week in .40 S&W using Precision Delta 180 gr. jacketed flat nose bullets. I shot them out of my Sig Sauer P226 Elite with a 4.4" barrel. These were fired outside when the air temperature = 36 deg F. Results were:
4.2 gr TiteGroup, 180 gr. JFN, OAL = 1.125, FPS = 844.9
4.7 gr TiteGroup, 180 gr. JFN, OAL = 1.125, FPS = 925.0
Earlier, I did some test loads with my Glock 23, using a KKM Precision barrel instead of the factory barrel. I used Rainier 180 gr. hollow point, flat based bullets. These were fired outside when the air temperature was approx. 65-70 deg F. Results:
3.8 gr. Titegroup, 180 gr. HPFB, OAL = 1.125, FPS = 856.0
4.2 gr. Titegroup, 180 gr. HPFB, OAL = 1.125, FPS = 891.7
4.5 gr. Titegroup, 180 gr. HPFB, OAL = 1.125, FPS = 933.6
YMMV, these were my results. Oddly enough, when my Sig was new, I tried using some 165 gr. bullets with 4.2 gr. of TiteGroup. This load would work well in my Gen 4 Glock 23, but would not cycle the action of the Sig reliably; I'd get a lot of stovepipes. Upping the load to 4.7 solved the problem, but now that the Sig is 'broken in' it seems to shoot everything well. Still feels like a heavy recoil spring though, but it works just fine!
