My favorite is a gen 4 27. It's as accurate as my 23, it'll put a Federal 180gr HST out of the barrel at a chronographed 1003fps (Federal lists that round at 1010fps). I carry it tight to my side with the 9 round mag when I really want to be concealed but my spare mag is a 13 rounder with a grip sleeve that make it feel like my 23. I also have a 15 round mag and sleeve to replicate the capacity of the 22 (which I sold. You can always make the little gun big but you can't make the big one little.) I can carry the 27 on my ankle in a Galco Ankle Glove and I forget it's there. It is so versatile, accurate and hard hitting it would be the last gun to be sold before my gen 4 19.Because of it's conceal-ability. My EDC has been a Sig Equinox for quite some time. Recently on two separate occasions. When I un holstered my Sig 239 Equinox at the range. The gun went click instead of boom! I promptly dispatched it in exchange for a G27. And then a G43. Both are easily concealed. They must sprinkle crack on Glocks because I want more. I'm not kidding, like now! If you were going to buy a full size Glock, what would it be? I'm typically a .40 person but I'm thinking G34. Thoughts?
Don't necessarily overlook a real power house, the G29 (10mm.) I'd heard so much about the mighty, nasty 10 that the first time I pulled the trigger I expected to have both wrists broken and my skull split from the muzzle jump. But, wth??!!. My first thought was, "My 23 kicks harder than this." I liken the recoil to a mix of the smack of the 40 and the push of the .45. It's very manageable and will soon become my EDC. Why hit something with a 180 gr bullet travelling at 1,000fps out of a .40 when you can send the same weight bullet out at 1175fps (actual chrono reading.) And the 10 loves 200 gr bullets for hunting. A 200 gr Hornady XTP moving at 1150fps has more muzzle energy than the vaunted 125 gr Federal .357 mag. And I guarantee it's much easier to shoot. You can also use the full sized (G20) mags with a sleeve for 15+1 rounds.)
I love 10mm and Glocks, but never got along with the G29/30 size guns. It's somehow both too small and too big at the same time. It gets the wider, heavier slide ala the G20/G21, so it weighs much more than a G23/G19/G32, and has the short grip of the G26/27/33.
So for my 10mm itch, it's only G20 or (even better) G40.
Dang, I miss my G20.
I also found my G30 gen 4 to be a great gun. It was more accurate than my 21 so I sold the 21. I'm just kinda into 10mm right now. But you can't go wrong with a .45. It has been saying, "Stay away from me and my family/country for 115 years now."I'll echo that sentiment. I sold my G20 a while back and as with just about every gun sold, I regret selling it now. But, I do still have a G21 and recently bought a G30 to go along with my G27/G23 combo. It's funny how two people can see the same thing differently. For me, I think the G30 is near the perfect carry gun. 10+1 rounds of .45 in a concealable package that is really soft shooting. I like the heavier slide because it dampens the recoil somewhat. I shot my nephew's G30S a while back and thought it felt harsh for a .45. The G30sf is a sweetheart by comparison.
But yeah, I do miss the G20sf now.
