for all practical purposes, nowadays, without getting into extended mags, the 1911 45ACP is 8+1. for Hawaii, the Glock 21 is 10+1. the HK45 with standard mag is 10+1 for the world. Gotta admit, a good 1911 is a beautiful piece of craftsmanship, bordering on art, but also, the economy USGI mil-spec 1911 sure leaves a lot to be desired, the as-issued 1911A1 horrible front sight, and you have to go to a real gun smith machinist to have a dove-tail installed. just my 2 cents.
to improve a Glock trigger (above all, without compromising safety!), is rather straight-forward: pre-travel, over-travel, springs out the wazoo, connectors, triggers ala carte or complete drop-in, and judicious polishing of sliding surfaces. The Glock 17/19 have sort of become the "small block Chevy" of the gun world, with infinite aftermarket improvements and hot-rod add-ons, totally cloned. Even red dots (RMR) have become simple bolt-ons for Glocks. To improve a 1911 trigger, in my mind, best left to a qualified gun smith that's got the jigs, the angles, and the range of polishing stones.
in Hawaii, with 10rd mag limits, I don't see the point for a Glock 17 (unless you're in the LEO upper caste, unlike us bottom feeder civilians), or unless you really want that 0.47" extra barrel length. Sorta like the Colt Commander gives up 0.75" barrel length at 4.25", but still 8+1. The G19 makes more sense for Hawaii, you're still giving up 5 rds capacity compared to the free states, vs 7 rds for the G17, and you still get a full hand grip, and a legitimate (for 9mm) barrel length. The Glock 26 with the Pearce grip extension (Hawaii legal +0) fills the hand nicely, but the abbreviated rear bottom of the grip leaves the bottom of the palm wrap-around a little lacking, and with only maybe 2" of rifled barrel, probably similar to a Chiefs Special but with 10+1 rds. In my mind, the G26 is a nice package also, but certainly not a micro-gun.
Just off-the-top of my head, miscellaneous observations and ramblings. not to be taken as gospel, YMMV.
