I use TiteGroup for both the 9mm and the 45 ACP. I use 5gr. of TG in the 45 with a 200 or 230 bullet with perfect results. With the 9mm, I load 4.8 with the 115 and 4.4 with the 124 gr. bullet. Ideally, one would start low and work up until the pistol in question functions reliably and go with that. TG is just about all I use for auto rounds except for the 10mm. Bob!
