Wild Romanian:
A couple of points off your email:
Controls on a pistol should really depend on how they work with you when drawing (in a real hurry) and shooting. Easily accessible controls do not assist in this if they do not help you shoot.
Hammer design: Easier to cock? I have a 1911 that has not been uncocked for a couple of years, loaded, unloaded, or firing. There is no reason to cock a 1911 as it should not be uncocked - at least with a round in the chamber!! (And if you didn't have one in the chamber you're in no hurry, or if the hammer isn't cocked, you need to rack the slide get to it!).
World Acceptance: I'm not calling people who choose the 9mm wussies; but the European police sensibilities are hurt by 45acp and shotguns - they see it as ultra barbaric (although seeing cops with MP5s does not scare them so much). The 45ACP puts the 1911 out of the question in Europe.
Grip size: Take the grips off your 1911. . . . THAT is the true grip size and it's tiny, try it that way. Okay, you want smaller? Install a pair of AFS Slimtech. Some double-stack guns claim sub-1911 grip size; but they're counting the oversize slabs in the mix. Of course, the Berretta is in its own league here - besides width is the trigger pull length - one has to pull the world's nastiest double-action trigger at that distance - it must be because I'm only 6 foot 5.
Slide release positoning wrt. grip: You're not supposed to be able to reach the slide release! If you have a gun where you can push the slide release with your right thumb take it back to the store - wrt. what I said before, choose the grips that let you get off 7/13 quality shots as easily as possible, not reach unnecessary buttons. I can still recall the horrors of my time with an extended slide release - oh, the humanity! Your controls that are in reach should let you draw, safety off (if necessary) and score accurate hits. A slide stop (yes, it's a stop, not a release, although we can use it as such if we like) that is within reach will get knocked on while firing - maybe not when we settle into our favorite target stance but in real life rolling in the dirt confusion. Want to drop the slide? Use that other hand that reached for the mag while it's settling into firing position, or your thumb. You don't want to be able to touch that thing while shooting! Yeah, right thumb MAY save you a nanosecond on the reload (unlikely with good technique as after ramming the mag home you have a left thumb right in position). I hypothesise that if a fight is going to require a reload, it's certainly going to require 7 well-placed without a premature slidelock!
That said, the Beretta has something for folk who want to accomplish the unnecessary (and intrusive!) in a real hurry, a big fat ambidextrous click-me-fast-and-look-cool-when-the-gunfight-is-over-in-Lethal-Weapon decocker. Now THAT is something cool to do with one's weak hand while wounded in a gunfight - maybe it needs a nice spur hammer to match
BTW - the mag catch is another thing I don't want accessible from a firing grip. Have a friend with a Kahr 40 that drops its mag while shooting (just far enough to not feed).
