If the Glock and M&P don't quite work for you, try a SA XDm. Very ergonomic and interchangeable backstraps to fit the pistol to your hand. Mine is in .45 ACP and it is a tackdriver. I have a Powder River Precision trigger kit in mine that makes the trigger almost as good as a really good 1911 trigger. There are match kits and then there is the carry kit which is more suitable for defense applications. All XDms have a reputation for superb accuracy. Mine is a tackdriver. 14 rounds of .45 ACP firepower.
