What would be your "close second" choice?
I agree that the 19 is probably the best all-around package. Just that it's so close to the 17 that I'm wondering if something that's a little bit more different is worth a try.
The Glock 26/27 or Glock 17 would be my next choices and that would be dependent on my attire and mode of carry, but I primarily carry AIWB, but do at times hip carry, ankle carry or man bag carry. I have also carried a full size P226 and 1911's quite a bit.
I carry AIWB and can do well with the 19 and the 17. The 17 needs to ride a bit higher so the muzzle doesn't dig and the 34 is just too long. The 17's grip will print a bit more holster / carry / clothes dependent, so that is a consideration. So yes, the 19 is noticeably more concealable than the 17 again dependent without giving up too much.
I do however find that the 19's grip needs alteration more so than the 17 to fit my hand better. On the plus side is that I do my own customization work on the pistols and I have custom holsters made to fit my needs and the different pistols. I like my AIWB holsters to ride a bit higher, with slight cant to the primary side. I like it wedged or tucked, but not both, prefer the wedge. There are a few companies making these type of holsters commercially now and Frank Proctor released a model nearly identical to how I have mine custom made.
I like Glocks quite a bit and I know a lot of people were screaming for a single stack baby Glock, but I don't like it. I actually prefer the G26/27 and the larger circumference of the double stack small Glock. I am not a fan of the M&P and will not get into that discussion, however I do like the shootability of the Shield over the G43, but I don't prefer any pistol that small as a primary carry unless if a special circumstance dictates something that small. I am also a fan of the Sig Sauer P320 and would consider it in the carry configuration. I am not a fan of the VP9 but it is also a good sized option. There are other steel framed options out there also, like the 229, P07, etc..
This is my G19 and how I like to set it up. Many features have been adopted by Glock on the 17M and may trickle into other models. It took the necessity of meeting features for a contract to make these changes, but they are a long time coming and good improvements to the pistol that many of us have been doing aftermarket for years.
- Remove finger grooves and texture front strap only. 360 texture is too much for the love handles and stock texture on Gen4's are perfect.
- Undercut trigger guard.
- Radius sides of trigger guard, or basically dehorning sharper edges. This makes fingers fit even better on the smaller 19's grip. Greatly reduces Glock knuckle on all models.
- Memory cut underside of trigger guard and textured.
- Texture side flats.
- Change magazine release button.
- Change slide stop lever.
- Flared magwell with grip plug to enhance magazine feeding / insertion.
- Cut on bottom side of front strap to strip mags.
- Aftermarket sights.
- Cleaned up internals.
