Why are you making users haul empty laptops back and forth?

Nope, not much more than with jacketed. I'm not sure where the myth of "don't shoot lead in Glocks" started, but it's very persistent. With any reloading (or shooting), it's obviously important to make sure fouling doesn't reach dangerous levels. But in the average IDPA match I shoot about 125-150 rounds with no noticeable leading. The barrel gets a bit dirty from the lube on the lead bullets, but I run a Boresnake through it at the end of the match as it's like new again.

Nearly all my recipes are for Missouri Lead Bullets, only loads I shoot jacketed are full power .357 Magnum loads.

And .38, and .357, and .44....

I use Missouri Bullet Company's 9mm/125gr Smallball in my Glock 19 with a charge of 4.2gr Alliant Bullseye powder. Works really well for me with minimal leading.

Shooting jacketed would bring the prices up some, but lead bullets work well enough for me and the load should just meet IDPA power factor requirements (Though I haven't chronographed it).

Cost per 1000 rounds
Primers $30
Powder $10-ish (7000gr per lb, so I get ~1500 rounds per bottle)
Brass - Free range pickups
Bullets $60

Total $100 / 1000 and a Saturday spent by the reloading bench.
$100 / 1000 = $0.10 / round = $5 / 50.

Any questions, let me know. I'm not an expert by any means, but I can maybe save you a little bit of time :-)

to the world little one.

Still kinda here.

Why not retrofit every home with sprinklers?

Are you saying councilman, that it's acceptable for people who can't afford new homes to be burned alive?

Hmm, except that "Congress shall have Power To ... provide for the common Defence ... of the United States", you could easily argue that assisting with training and equipping the people is part of governments responsibility as a well regulated Militia, is necessary to the security of a free State.

See Civilian Marksmanship Program for instance.

Silly, just blur the terrorist bases and let the problem solve itself.

Yeah, longer sight picture would be the biggest benefit with the extended slide.

Not to push the issue, but a 4-6" revolver with .38 target loads is comparable to a 9mm in recoil, my wife has a couple revolvers and much prefers them to pistols. Partly because she doesn't get hit by flying brass. Have your wife look at someone doing the hot-brass-down-the-cleavage-dance-videos and see how she feels about that prospect :-)

But if revolvers aren't your thing, you might want to look at a Government sized 1911 in 9mm. It's a heavier gun so less recoil, longer slide with a 5" barrel, the best trigger of any pistol, external safeties. To me that sounds very much like what you're looking for.

In the end of course it may come down to what you want to get, not what fulfills certain requirements. Glocks are fine guns that go bang every time. The wife owns a Taurus revolver, and I wouldn't mind getting one. But I wouldn't get a Taurus semi-auto, there are better ones out there for not much more money. Of the choices you've listed, I'd get the Glock 17L. 17L rather than 34 simply because the 17 is an extremely popular gun and you shouldn't have any problem finding parts for it.
