Regrding the magazines, the problem has been with Glock OEM 10 rounders for the G17 and G19, particularly with hollow point bullets. However, the Magpul 10 rounders have played to some pretty decent reviews recently; I'm personally experimenting with them as a "just in case" alternative, but I haven't actually used them so I can't offer a personal empirically based review yet.
Best, Jon
Those are all excellent reasons not to go with a G19, or any Glock, period. IMNSHO another reason would be if the shooter has a trigger finger too short to reach the trigger properly without causing the web of the shooting hand to fail to line up properly behind the grip, or if, like mine does, the trigger finger drags on the frame.
I say these things as someone who carried Glocks (23 and 30) during 1999-2003 and again during 2008-2019 (17, 19, and 34).
I recommend to the original poster that he try to find someone local to him who has the knowledge, willingness, and skills to guide him through this process.
I would add two things. One, try several things at a rental range, as you may find you shoot something better/prefer it. Two, don't forget used guns.
While polymer guns tend to be cheaper new, I have found deals on used metal guns in the four hundred dollar range, prepandemic (that has had an n effect on everything.) Examples, CZ 75 P01, CZ 75 PCR, several revolvers (LCR), few 92's.
Knowing only that, the trite answer is "get a Glock and be done with it". And that's "not wrong".
Manufacturer support is important. Warranty. Parts availability. Magazines -- how available are magazines? Rare and precious, or cheap enough to stock up? (Because you ought to have some extra.) How good is aftermarket support? Can you get a good holster? If it's an Every Day Carry item, it's going to be in that, and on your body, almost all the time, so that's important.
If you're just starting on this, you'll make mistakes. Join the club. Accept it, sell it off and move on.
Don't believe everything you read on the Internet.
If I were starting fresh with no spare parts, mags, holsters, etc, I would go with a CZ P07 AIWB and call it good.
When I hit 21 I owned two guns: Colt SAA 7.5" in .45 Colt and an 8 3/8th" Smith & Wesson 29-2 .44 mag. Both non-starters for CCW of course.
I swapped the 29 for a 1911 made during the Great War that had been fully customized. Loved it but couldn't carry it at work as it was too damn big. Loved the pistol and now I was out of choices. A .38? Too small. A 9mm? Who in their right mind would carry a Luger or a Walther P38? Since there was no such thing as a hollowpoint bigger ball is better ball, obviously.
Then I discovered the Charter Arms .44 Special Bulldog. Small cap, so so quality but it was a big bore and I could carry it 24/7. Appendix inside the waistband was my thing in early '75 and I've stayed with it. Moved on from the Bulldog as soon as I Detonics came out.
That was a while back now that I think on it.
