I think the X -Cal or X-Trim either one would work, the X-Cal has a longer sight radius. should have no problems under teh 2.5" mark. Depending on bullet selection.
CZ makes a SP01 Tac 2, which does not have the heavier dust cover, but still isn't as light as the Grand Powers. If you go that route, check the test target before you buy, some are ok on accuracy, some are phenomenal. The cool part is they come with a test target. I must say there is one on gun broker Easy pay right now that I've almost bought twice.. if ONLY it ha the light rail. lol
